Update of the Xylella spp. host plant database - systematic literature search up to 31 December 2021.

This Scientific report provides an update of the Xylella spp. host plant database, aiming to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp. Upon a mandate of the European Commission, EFSA created and regularly updated a database of host plant species of Xylella spp. The current mandate covers the period 2021-2026. This report is related to the sixth version of the database published in Zenodo in the EFSA Knowledge Junction community, covering literature published from 1 July 2021 up to 31 December 2021, and recent Europhyt outbreak notifications. Informative data have been extracted from 29 selected publications. Eleven new host plants were identified and added to the database: six plant species naturally infected by subsp. multiplex of X. fastidiosa in the EU (France, Italy and Portugal) and five plant species artificially infected by different X. fastidiosa subspecies (multiplex, pauca, fastidiosa and sandyi). No additional data were retrieved for X. taiwanensis. New information on the tolerant/resistant response of plant species to X. fastidiosa infection were added, while no new STs have been identified worldwide compared to the previous update published in January 2022. The overall number of Xylella spp. host plants determined with at least two different detection methods or positive with one method (between: sequencing, pure culture isolation) reaches now 412 plant species, 190 genera and 68 families. Such numbers rise to 664 plant species, 299 genera and 88 families if considered regardless of the detection methods applied.

Introduction

Background and Terms of Reference as provided by the requestor

In the context of Article 31 of Regulation (EC) No 178/2002, EFSA was asked by the European Commission DG SANTE to provide technical assistance in the field of plant health as regards the regulated harmful organism Xylella fastidiosa, as per letter to EFSA’s Director dated 30 June 2016 (Reference ARES(2016)3126989).

EFSA was requested to further specify and update the host plants database of X. fastidiosa available in 2016 (EFSA, 2016) taking into account the different X. fastidiosa subspecies and strains (with particular reference to the European isolates), with the inclusion of information on non‐susceptible plants and varieties and negative results of diagnostic tests when available. EFSA was requested to maintain and update this database periodically and to make new releases available on the EFSA website, together with a Scientific Report. The database should focus on plants confirmed to be infected by at least two detection methods in field conditions or via vector transmission under experimental conditions. Such request was for the period 2016–2020.

This mandate was extended by the European Commission DG SANTE for the period 2021–2026, with the aim to continue the update of that database. EFSA is requested to deliver two updates per year of the database.

Interpretation of the Terms of Reference

EFSA delivered in September 2018 a renovated database of host plants of Xylella spp., taking into account both species of the genus Xylella (X. fastidiosa and X. taiwanensis) (EFSA, 2018), which was last updated January 2022 (EFSA, 2022). Raw data and interactive reports were published in Zenodo in the EFSA Knowledge Junction community and in Microstrategy platform, together with a Scientific Report.

As per terms of reference (ToR), EFSA was requested to maintain and update the Xylella spp. host plant database for the period 2021–2026, and to publish new releases online together with a report twice per year. This Scientific Report provides a new update on the database of host plants of Xylella spp. published in January 2022 (EFSA, 2022). An extensive literature search was conducted to retrieve recent publications on the topic and new informative data on host plant species of Xylella spp. were collected. Such report provides information on the literature review and a detailed view on the currently known host plants of Xylella spp.

Data and methodologies

The methodologies developed for the Xylella spp. host plant database published in 2018 (EFSA, 2018) were applied in this report.

The process was divided in the following steps:

Extensive literature search to identify relevant references.

Selection of studies based on title, abstract and full text.

Data extraction of relevant information.

Data analysis and reporting.

Extensive literature search

The review question ‘Which plant species can host Xylella / Xylella associated disease?’ was broken down into key stages using the P/O conceptual model described in the EFSA systematic review guidance (EFSA, 2010):

Population of interest (P)

The population of interest is that of plant species, worldwide.

Outcome (condition of interest) (O)

The outcome (condition of interest) is that of Xylella spp. infection.

Two main elements were considered for the extensive literature search: the sources of information (Table 1) to be consulted and the search strategy (Table 2).

Information sources

The search strategy was run in all databases listed in Table 1 via the Web of Science (Clarivate Analytics) and Scopus platforms with no language or document type restriction.

Search terms

The syntax of the search string, developed for the Xylella spp. host plants database published in 2018 (EFSA, 2018), was adapted and run into each platform databases listed in Table 1 on 27 January 2022. As the scope of the search was to retrieve references published after June 2021, the selected time span was from 1 July 2021 up to 31 December 2021. The search strings and the number of retrieved references are shown in Table 2.

The collected references were downloaded and imported into an EndNote X9 library (Clarivate Analytics). Duplicates and references already included in the update published in January 2022 (EFSA, 2022) were removed using EndNote X9 and the remaining references were uploaded on DistillerSR online together with the full texts in portable document format (pdf).

Nine Europhyt outbreak notifications (accessed on 7 March 2022), two XF‐ACTORS Project deliverables (D2.3 and D7.4) and one official communication notified by the Istituto per la Protezione sostenibile delle Piante ‐ CNR, Bari (Italy) were also included.

Study selection

The collected references were screened for relevance in two steps:

Title and abstract screening.

Full‐text screening of the references that passed the first step.

Inclusion/exclusion criteria were applied in each step and two reviewers worked in parallel screening the references.

The first step required the reviewers to answer two questions, listed in Table 3, considering only title and abstract of the references. The aim of this step was to select only references presenting original research data on Xylella or Xylella‐associated disease.

Table 3

Inclusion/exclusion criteria for title and abstract screening

Question text	Type of answer	Answer text	Exclusion criteria
Is Xylella/a Xylella‐associated disease/a Xylella synonym the topic of the study?	Only one of the possible alternative answers can be selected	Yes	Included
		No	Excluded
Is it a primary research study?	Only one of the possible alternative answers can be selected	Yes	Included
		No	Excluded

The references that passed the first step were submitted to the full‐text screening. This second step required the reviewers to answer four questions (Table 4): three of them are descriptive (neutral) whereas the fourth has an inclusion/exclusion role.

Data extraction

Informative data listed in Table 5 were extracted from the selected references. For each reference, the first reviewer performed the data extraction whereas the second reviewer conducted the quality check of the extracted data. Data extraction from each reference can generate one or several records. A record is defined as a unique combination of data related to a detection event, and it corresponds to a single Excel row of the files published in Zenodo (see Section 2.4.1).

Data warehouse

A harmonised data model has been established to collect data on Xylella spp. host plants. The aim was to establish a harmonised data flow for the collection and the collation of an extensive literature review generated data in the plant health domain. Data are stored in EFSA Scientific Data Warehouse (S‐DWH), after that an ETL (Extract, Transform, Load) procedure is applied in order to harmonise and calculated the statistics.

Data management

The collected data have been submitted to the EFSA Data Collection Framework (DCF). DCF is the upfront system in the EFSA pipeline of data collection tools and allows a first step of harmonisation against the EFSA controlled reference terminology (aka EFSA catalogues). Data have been then included in the S‐DWH by means of a standardised Extract Transform Load (ETL) procedure and they have been further analysed and managed to generate needed statistics.

Data are available as interactive reports on the Microstrategy platform at the following link: https://www.efsa.europa.eu/en/microstrategy/xylella

Raw data and related metadata are published in Zenodo in the EFSA Knowledge Junction community, this report refers to Version 6 (https://doi.org/10.5281/zenodo.1339343).

Data reporting

Data reporting was designed to distinguish the Xylella spp. host plant species, based on the number and type of detection methods applied for each finding. Different combinations of detection methods were considered:

A. Plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation).

B. The same as point A, but also including microscopy: plant species positive with at least two detection methods (among: microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation).

C. Plant species positive with at least one detection method (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation).

D. Plant species positive with at least one detection method including microscopy (microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation).

E. All positives plant species reported, regardless of the detection methods (positive records but without the detection method specified, symptom observations, microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing, pure culture isolation).

Results

Results of the literature review

The extensive literature search was conducted on 27 January 2022 on Web of Science and Scopus platforms and 163 references were collected. Duplicates and references already included in EFSA (2022) were removed and 100 references were uploaded in DistillerSR and screened for relevance. Results of the screening process are shown in Figure 1.

Figure 1

Flow diagram of the screening process

In the first step, i.e. title and abstract screening, 70 references were excluded either because they do not focus on Xylella or Xylella‐associated diseases and/or they are not primary research studies. The selected 30 references were subjected to the second step of the screening process, i.e. the full‐text screening. Seventeen references, in which Xylella spp. is studied is association to a host plant, were selected. Nine Europhyt outbreak notifications containing informative data were also included in the data extraction. Data were also collected from XF‐ACTORS Project deliverables D2.3 ‘Host range of relevant Xylella fastidiosa strains and isolates harbouring novel STs’ , D7.4 ‘Identification of plant species that can serve as alternative crops in the EU contaminated areas’6 and from official communication notified by the Istituto per la Protezione sostenibile delle Piante ‐ CNR, Bari (Italy). Totally, 29 references (listed in Appendix E) were included in this update of the database and from which informative data listed in Table 5 were extracted.

Update of records already included in the database

Scientific names of plant species, genera and families are reported, as far as possible, accordingly to the taxonomy of the EPPO Global Database (EPPO, 2022) that is constantly being updated. Therefore, changes of scientific names of plant species, genera and families in the Xylella spp. host plant database are related to the update of the taxonomy in the EPPO Global Database. In line with this, the plant species Osteospermum ecklonis (EPPO code ‘OSPEK’) and O. fruticosum (EPPO code ‘OSPFR’) have been renamed Dimorphotheca ecklonis and D. fruticosa, respectively.

Records referring to Europhyt outbreak notifications, that may contain incomplete data, are updated whenever additional information (e.g. further identification of the plant species, X. fastidiosa subspecies, ST, etc.) become available. This is the case of the plant species Nerium oleander, previously reported infected in Mallorca (ES) by undetermined X. fastidiosa subspecies, afterwards identified ad subsp. multiplex ST81 (recordID 9724).

Few records with no indication of the plant species (recordID 2891, 6643, 7113, 7114, 8171 and 11148) were deleted from the database. Records (recordID from 10914 to 10925) referring to plant species reported in Table 3 of the publication Gorris et al. (2021) (refID 3835) were also deleted as erroneously interpreted infected by X. fastidiosa in the previous published version of this database (EFSA, 2022).

Host plant species of Xylella spp.

The updated numbers of host plant species, genera and families (according to the different categories reported in Section 2.4.2) are reported in Figure 2 and Table 6. The number of plant species raised to 412 according to category A [i.e. plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation)] to 664 plant species of category E (i.e. all positives plant species reported, regardless of the detection methods).

Compared to the previous update of the database published in January 2022 (EFSA, 2022), 11 plant species and 7 genera were identified as new hosts of X. fastidiosa. Those plant species and genera were not previously reported in the database. Details of those new hosts of X. fastidiosa are summarised in Table 7.

All the six new plant species found to be naturally infected were identified in the EU (France, Italy and Portugal) and were infected by subspecies multiplex. Artificial infection has been successful in five new species. Jasminum azoricum was artificially infected, successfully, by the subspecies pauca, either by needle inoculation or transmission via the vector Philaenus spumarius.

Within the XF‐ACTORS project, the susceptibility of Pyrus communis (to subspecies fastidiosa, multiplex, pauca and sandyi), Malus domestica (to subspecies multiplex, pauca and sandyi), Quercus petraea (to subspecies fastidiosa, multiplex and pauca) and Salix alba (to subspecies fastidiosa, multiplex and pauca) has been proved in artificial infections by needle inoculation. Although in these experiments conducted under greenhouse conditions, the pathogen was detected at some distance from the inoculation point (e.g. 40 cm, as reported in the case of Pyrus communis and Malus domestica), further studies will need to prove whether these new hosts are likely to sustain infection under natural conditions.

The overall number of host plant species infected naturally, artificially and in unspecified conditions by the different X. fastidiosa subspecies and according to the different categories are reported in Tables 8, 9 and 10. The plant species behind the numbers shown in those tables are listed in.

Appendicies A, B and C. In those appendices, the full lists of plant species infected by the different X. fastidiosa subspecies naturally, artificially and in not specified conditions according to the five categories are shown.

The highest number of plant species naturally infected is recorded for X. fastidiosa subsp. multiplex (203 according to category A, up to 210 for category E), followed by subsp. pauca and subsp. fastidiosa. In artificial infection, 40 plant species (category A, and 79 for category E) were successfully infected by X. fastidiosa subsp. fastidiosa. Twenty plant species were artificially infected by subsp. pauca and 19 by subsp. multiplex (category A), up to 33 and 32 for category E (for pauca and multiplex, respectively).

No new host plants were reported for the pathogen species Xylella taiwanensis that so far was recorded only in Pyrus pyrifolia plants.

X. fastidiosa Sequence Types and host plants association

The full list of plant species infected by the different X. fastidiosa sequence types (ST) in natural, artificial and not specified conditions is reported in Appendix D. For each plant species, the number of records reporting infection by that specific ST is counted. For natural infection, it is also reported the country where the plant species have been identified, whereas for artificial and not specified infection only, the total number of records is present in the appendix.

Totally, 2,179 records reporting information on 249 plant species infected by 87 different STs have been reported in the database. Most of the records (1,585) refer to natural infections that were reported in North, Central and South America (United States of America, Mexico, Honduras, Costa Rica, Ecuador, Brazil and Argentina), Europe (Portugal, Spain, France and Italy). The highest number of records for artificial infections belongs to STs of subsp. pauca (246 records). While ST1 (subsp. fastidiosa) still remains the most used ST in artificial infections, now with 171 records, ST53 (subsp. pauca) is the most reported genotype in natural infections (456).

Compared to the previous version of the database (EFSA, 2022), no new STs have been identified worldwide. ST87 belonging to subsp. multiplex and identified in 2018 in Tuscany (Italy) hence remains the last sequence type identified so far, and therefore included in our database.

Tolerant and resistant response of plant species

Information on tolerant and resistant response of plant species to X. fastidiosa infection have also been reported in the database. The list of plant genera and species for which tolerant and resistant response have been identified is reported in Table 11. Seventy‐seven additional records that include this information have been inserted in the database compared to the previous version (EFSA, 2022). Information on tolerant/resistant status is now reported for 72 plant species with a total number of 708 records.

The most studied genera are Vitis, Citrus and Prunus (417, 175 and 58 records, respectively), confirming the important economic value of these crop plant species. Almost all of the new records added to this update are related to several accessions of the plant species Vitis arizonica, V. berlandieri, V. candicans, V. girdiana, V. monticola and V. riparia (72 records), while new information on tolerant and resistant responses have continued to be made available with reference to Leccino, Nocellara messinese, Frantoio and FS‐17® cultivars of Olea europaea (five records), which now gathers 30 records.

To the aim of this study, different tolerant/resistant response to X. fastidiosa infection has been grouped into 11 categories, as reported in Table 12. Those categories include the plant response/s for which the authors of the publication considered that plant as tolerant/resistant to X. fastidiosa infection. One hundred and twenty‐nine publications, which match 708 records, for the most part (442) reporting artificial infections, return information on tolerance and resistance outcome to X. fastidiosa infection. In 43 publications, the authors consider the plant tolerant or resistant, but without adding further details, whereas in 23 publications (and 242 records), the plant is designated tolerant or resistant based on a lower bacterial population it harbours. In 235 cases, this finding comes from artificial infections. The lack of infection and the lack or reduction of symptoms (78 records in each case) are the two most reported tolerant/resistant outcomes in natural infections.

Conclusions

Following a request from the European Commission, EFSA was asked to create, maintain and regularly update a database of host plant species of Xylella spp. This Scientific Report summarises the most interesting information reported in the new version of the database (Version 6).

An extensive literature search was performed including all scientific papers published up to 31 December 2021, as well as additional Europhyt outbreak notifications (last accessed on 7 March 2022), two deliverables released by the Horizon 2020 XF‐ACTORS Project and an official notification from the Institute for Sustainable Plant Protection – CNR, Bari (Italy).

By these searches, 29 publications were selected and informative data were extracted.

Eleven host plant species and seven genera were identified as new hosts of X. fastidiosa. Those plant species and genera were not previously reported as hosts of X. fastidiosa. Six plant species were identified in the EU (France, Italy and Portugal) as new natural hosts of subspecies multiplex. The X. fastidiosa subspecies pauca was first described as being able to infect, in artificial trials, Jasminum azoricum, a species hitherto never included among susceptible hosts. Two plant species (Salix alba and Quercus petraea) were artificially infected by subspecies fastidiosa, multiplex and pauca, whereas Pyrus communis also proved susceptible by artificial infection to a fourth subspecies (i.e. sandyi). Malus domestica was artificially infected by subspecies multiplex, pauca and sandyi.

It is worth noting that, in the case of Pyrus communis, Malus domestica, Salix alba and Quercus petraea, the identification of artificial infections, with different X. fastidiosa subspecies, is the result of a series of greenhouse trials under controlled and forced conditions, which were conducted as part of the XF‐ACTORS project. The actual infectious potential of the pathogen in these hosts will need to be verified with additional trials, or once identified under natural conditions.

Compared to the previous version of the database (EFSA, 2022), no new STs have been identified worldwide and no new data were retrieved for X. taiwanensis that, up to now, still remains reported only in Pyrus pyrifolia plants.

The overall number of Xylella spp. host plants reaches now 412 plant species, 190 genera and 68 families for category A [i.e. plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR‐based methods, sequencing and pure culture isolation) or positive with one method (between: sequencing, pure culture isolation)], till 664 plant species, 299 genera and 88 families for category E (i.e. all positives plant species reported, regardless of the detection methods).

Information on tolerant/resistant status were reported for 72 plant species in 124 publications, with a total number of 708 records. The most studied and reported plant taxa are still the economically important genera Citrus, Prunus and Vitis. The latter also collects almost all of the newly acquired information on resistance or tolerance responses to infection (72 records out of 77 new additions).

A further update of the EFSA database on Xylella spp. host plants is planned for the end of 2022 with the aim to provide useful information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp.

Data are available as interactive reports on the Microstrategy platform at the following link: https://www.efsa.europa.eu/en/microstrategy/xylella

Raw data and related metadata are published in Zenodo in the EFSA Knowledge Junction community, this report refers to Version 6 (https://doi.org/10.5281/zenodo.1339343).
