Update of the Xylella spp. host plant database - systematic literature search up to 31 December 2020.

Following a request from the European Commission, EFSA was asked to create and regularly update a database of host plant species of Xylella spp. Complying with an extension of the previous mandate, which now covers the period 2021-2026, the current version of Xylella spp. host plant database updates the previous release dated April 2020. Informative data have been extracted from 86 recent publications retrieved through an extensive literature search. This report is related to the fourth version of the database published in Zenodo in the EFSA Knowledge Junction community, covering articles selected from: a systematic literature review conducted up to 31 December 2020, Europhyt outbreak notifications up to 18 March 2021 and communications from research groups and national authorities. Forty-three new host plant species of X. fastidiosa, identified through the data extracted from the selected publications, have been added to the database. Those plant species were reported as naturally or artificially infected by subsp. fastidiosa, multiplex, pauca or unknown (i.e. not reported in the publication) subspecies of X. fastidiosa. New information on the tolerant/resistant response of plant species or varieties to X. fastidiosa infection is also reported. No additional data were retrieved for X. taiwanensis. This new version of the database includes no update on the number of Sequence Types (STs) identified so far, which remains unchanged. 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 385 plant species, 179 genera and 67 families. Such numbers rise to 638 plant species, 289 genera and 87 families if considered regardless of the detection method applied. The database will be issued twice per year, with the aim to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp.

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, 2018) 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 further updated in April 2020 (EFSA, 2020). Raw data and interactive reports were published in Zenodo1 in the EFSA Knowledge Junction community and in Microstrategy2 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 2020 (EFSA, 2020). 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 20 January 2021. As the scope of the search was to retrieve references published after June 2019, the selected time span was from 1 July 2019 up to 31 December 2020. The search strings and the number of retrieved references are shown in Table 2.

The collected records were downloaded and imported into an EndNote X9 library (Clarivate Analytics). Duplicates, references already included in the update published in 2020 (EFSA, 2020) and data set links were removed using EndNote X9 and the remaining references were uploaded on DistillerSR online3 together with the full texts in portable document format (pdf).

Thirteen additional documents containing relevant information were obtained from research groups, communications of national authorities and Europhyt outbreak notifications4 (accessed on 18 March 2021).

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 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 4 (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:

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).

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).

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).

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).

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 20 January 2021 on Web of Science and Scopus platforms and 873 references were collected. Duplicates were removed and 281 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, 162 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 119 references were subjected to the second step of the screening process, i.e. the full text screening. Seventy‐three references, in which Xylella spp. is studied is association to a host plant (i.e. in vivo), were selected. Data extraction of two selected references was postponed to the next update of the database foreseen in November 2021. Thirteen additional references retrieved from research groups, communications of national authorities and Europhyt outbreak notifications4 and containing informative data were included in the data extraction. Totally, 86 references (listed in Appendix E) were included in this fourth update of the database and from which informative data listed in Table 5 were extracted.

Update of records already included in the database

Two records already included in the previous versions of the database have been updated following expert personal communication to EFSA. The sample of Rosa sp. (RecordID 8094) reported in the reference RefID3207 was finally identified as Rosa × floribunda and the results of the analysis were unconfirmed/dubious. Unconfirmed records are included in the data extraction but excluded from the data analysis. In the same reference, the sample identified as Cistus sp. (RecordID8020) was further identified as Cistus monspeliensis. Both records were updated accordingly, and an explanatory comment was added to the database.

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 385 (179 genera and 67 families) 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 638 plant species (289 genera and 87 families) of category E (i.e. all positives plant species reported, regardless of the detection methods).

Thirty‐nine new host plant species were naturally infected and identified both in the EU (France, Italy, Portugal, Spain) and outside the EU (Costa Rica and United States). Only four new host plants were identified through artificial infections. The X. fastidiosa subspecies multiplex was identified in 24 new host plant species naturally infected in the EU. Six new host plants were infected by X. fastidiosa subsp. fastidiosa: three in artificial infections and three naturally infected (in Costa Rica, Spain and the United States). The X. fastidiosa subsp. pauca was identified in two new host plant species (one natural infected in Spain and one artificially infected), while in 12 new host plants, the X. fastidiosa subspecies was not reported (i.e. unknown).

Apart from one new host genus naturally infected in Costa Rica, and one artificially infected, the remaining 12 hew host genera were all identified as naturally infected in the EU (France, Portugal and Spain). The two new host families were reported in Portugal.

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 Appendices 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 (179 according to category A, up to 185 for category E), followed by subsp. pauca and subsp. fastidiosa. Eighty‐nine plant species were artificially infected with X. fastidiosa subsp. unknown (i.e. not reported) according to category A, raising to 216 for category E. Xylella fastidiosa subsp. fastidiosa was able to infect 39 plant species (category A, and 73 for category E) in experimental conditions.

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, 1,711 records reporting information on 231 plant species infected by 87 different STs have been reported in the database. Most of the records (1,273) 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 belong to STs of subsp. pauca (186 records), whereas ST1 (subsp. fastidiosa) still remains the most studied ST, now with 154 records.

Compared to the previous version of the database (EFSA, 2020), 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, although the number of species (26) and records (54) where this ST is reported has risen considerably since the last update.

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. Hundred and thirty‐five additional records have been inserted in the database compared to the previous version (EFSA, 2020), most of them belonging to the genus Vitis. Information on tolerant/resistant status have been reported on 70 plant species with a total number of 622 records, but the most studied genera are Vitis, Citrus and Prunus (342, 175 and 54 records, respectively), reflecting the important economic value of these crop plant species. Research on tolerance and resistance is also gaining increasing interest with reference to the Olea genus (23 records), due to several recent studies carried out in the Apulian outbreak on olive cultivar responses to X. fastidiosa strain De Donno infection.

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 nineteen publications, reported in 622 records, for the most part (367) due to artificial infections, return information on tolerance and resistance outcome to X. fastidiosa infection. In 42 publications, the authors consider the plant tolerant or resistant, but without adding further details, whereas in 22 publications (and 163 records in artificial infection), the plant is designated tolerant or resistant based on a lower bacterial population it harbours. With more than 70 records, the lack of infection and lack or reduction of symptoms are the two most reported tolerant/resistant outcomes in natural infection.

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 4).

An extensive literature search was performed including all scientific papers published up to 31 December 2020, as well as additional documents obtained from research groups, communications of national authorities and Europhyt outbreak notifications (last accessed on 18 March 2020).

By these searches, 86 publications were selected and informative data were extracted.

Forty‐three new host plant species, 14 new genera and 2 new families were identified as new hosts of X. fastidiosa. Those plant species, genera and families were not previously present in the database. Thirty‐nine of those new host plant species were naturally infected and identified both in the EU (France, Italy, Portugal, Spain) and outside the EU (Costa Rica and the United States). X. fastidiosa subspecies infecting the new host plants were fastidiosa, multiplex, pauca or not identified (unknown/not reported in the study). Compared to the previous version of the database (EFSA, 2020), no new STs have been identified worldwide and no new data were retrieved for X. taiwanensis that up to now has been reported only in Pyrus pyrifolia plants.

The overall number of Xylella spp. host plants reaches now 385 plant species, 179 genera and 67 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 638 plant species, 289 genera and 87 families for category E (i.e. all positives plant species reported, regardless of the detection methods).

Information on tolerant/resistant status were reported for 70 plant species in 119 publications, with a total number of 622 records. The economically important Vitis, Citrus and Prunus genera are still the most studied and reported plant taxa.

From 2021 onwards, the EFSA database on Xylella spp. host plants will be updated twice per year 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 4 (https://doi.org/10.5281/zenodo.1339343).
