Polyphasic taxonomy of Aspergillus section Fumigati and its teleomorph Neosartorya.

The taxonomy of Aspergillus section Fumigati with its teleomorph genus Neosartorya is revised. The species concept is based on phenotypic (morphology and extrolite profiles) and molecular (beta-tubulin and calmodulin gene sequences) characters in a polyphasic approach. Four new taxa are proposed: N. australensis N. ferenczii, N. papuaensis and N. warcupii. All newly described and accepted species are illustrated. The section consists of 33 taxa: 10 strictly anamorphic Aspergillus species and 23 Neosartorya species. Four other Neosartorya species described previously were not available for this monograph, and consequently are relegated to the category of doubtful species.

INTRODUCTION

Aspergillus section Fumigati includes species characterised by uniseriate aspergilli, columnar conidial heads in shades of green and flask shaped vesicles (Raper & Fennell 1965). Teleomorphic species belonging to the “Aspergillus fischeri series” of the A. fumigatus group (Raper & Fennell 1965) were placed in the genus Neosartorya (family Trichocomaceae) by Malloch & Cain (1972). Section Fumigati includes more than 20 Neosartorya species and 10 anamorphic species (Pitt et al. 2000; Samson 2000; Horie ; Hong et al. 2005, 2006, 2007).

Aspergillus fumigatus Fresenius is an ubiquitous filamentous fungus in the environment, and also an important human pathogen (Raper & Fennell 1965). Several Neosartorya species have been described as causal agents of human diseases including invasive aspergillosis, osteomyelitis, endocarditis and mycotic keratitis (Coriglione ; Summerbell ; Padhye ; Lonial ; Jarv ; Balajee et al. 2005, 2006). All of the Neosartorya species produce heat-resistant ascospores that are frequently encountered in different food products (Gomez ; Samson 1989; Tournas 1994). The several mycotoxins produced by these species may cause serious health hazard (Fujimoto ; Frisvad & Samson 1990; Larsen ). Some species also have valuable properties for mankind; e.g. N. fischeri strains produce fiscalins which effectively inhibit the binding of substance P to the human neurokinin receptor (Wong ), while A. fumigatus strains produce pyripyropenes, potent inhibitors of acyl-CoA:cholesterol acyltransferase (Tomoda ), the immunosuppressant restrictocins (Müllbacher & Eichner 1984), ribotoxins (Lin et al. 1995) and fumagillin that has amebicidal activity (McCowen ). Neosartorya spinosa can be used for the complete enzymatic recovery of ferulic acid from corn residues (Shin ).

Here we present an overview of the species belonging to Aspergillus section Fumigati based on analysis of macro- and micromorphology, extrolite profiles and β-tubulin, calmodulin, ITS and actin gene sequences of the isolates. We also describe four new homothallic Neosartorya species found in soil samples in Australia and Papua New Guinea using this polyphasic approach and list synonymies.

Morphology and physiology

The strains (Table 1) were grown for 7 d as 3-point inoculations on Czapek agar, Czapek yeast autolysate agar (CYA), oat meal agar (OA) and malt extract agar (MEA) plates at 25 °C, and on CYA at 37 °C. For Neosartorya species Hay infusion agar and SNA agar have also been used for inducing the anamorphs (medium compositions in Samson ). In some species e.g. N. tatenoi the anamorph could only be produced when growing the cultures at 30 or 37 °C on MEA + 40 % sucrose.

Analysis for extrolites

Extrolites were analysed using the HPLC-diode array detection method of Frisvad & Thrane (1987, 1993) as modified by Smedsgaard (1997). Extrolites were analyzed from cultures grown on CYA, OA and YES agar using three agar plugs (Smedsgaard 1997).

Isolation and analysis of nucleic acids

Isolates used for the molecular studies were grown on 2 mL of malt peptone broth [10 % (v/v) malt extract (Brix 10) and 0.1 % (w/v) bacto peptone (Difco)], in 15 mL tubes. The cultures were incubated at 25 °C for 7 d. DNA was extracted from the cells using the Masterpure™ yeast DNA purification kit (Epicentre Biotechnol.) following the instructions of the manufacturer. Fragments containing the ITS region were amplified using primers ITS1 and ITS4 as described (White ). Amplification of partial β-tubulin gene was performed using the primers Bt2a and Bt2b and methods of Glass & Donaldson (1995). Amplifications of the partial calmodulin and actin genes were as described (Hong et al. 2005, 2007). Sequencing reactions were performed with the Big Dye Terminator Cycle Sequencing Ready Reaction Kit and carried out for both strands. All the sequencing reactions were purified by gel filtration through Sephadex G-50 (Amersham Pharmacia Biotech, Piscataway, NJ) equilibrated in double-distilled water and analyzed on the ABI PRISM 310 Genetic Analyzer (Applied Biosystems). The complementary sequences were corrected with the MT Navigator software (Applied Biosystems). Unique ITS, β-tubulin, actin and calmodulin sequences were deposited in GenBank (http://www.ncbi.nlm.nih.gov) with accession numbers DQ534140, DQ534141 and EU20279-EU220287.

Data analysis

Sequence alignments were performed using CLUSTAL-X (Thompson ) and improved manually. The neighbour-joining (NJ) method was used for the phylogenetic analysis. For NJ analysis, the data were first analysed using the Tamura-Nei distance calculation with gamma-distributed substitution rates (Tamura & Nei 1993), which were then used to construct the NJ tree with MEGA v. 3.1 (Kumar ). A bootstrap analysis was performed with 1 000 replications to determine the support for each clade,.

PAUP v. 4.0 b10 software was used for parsimony analysis (Swofford 2002). Alignment gaps were treated as a fifth character state and all characters were unordered and of equal weight. Maximum parsimony analysis was performed for all data sets using the heuristic search option with random addition order (100 reps) and tree bisection-reconnection (TBR) branch-swapping algorithm. Branches of zero length were collapsed and all multiple, equally parsimonious trees were saved. The robustness of the trees obtained was evaluated by 1 000 bootstrap replications (Hillis & Bull 1993). Sequences from an A. clavatus isolate were used as outgroups in these experiments.

RESULTS AND DISCUSSION

Phylogenetic analysis

We examined the phylogenetic relatedness of species belonging to Aspergillus section Fumigati using sequence analysis of partial β-tubulin, calmodulin and actin genes including sequences of all known species. ITS sequences were determined from the new species and the species most closely related to them in the β-tubulin tree. The partial β-tubulin gene alignment included 453 characters. Among the polymorphic sites, 102 were found to be phylogenetically informative. The Neighbour-joining tree based on partial β-tubulin genes sequences is shown in Fig. 1. The topology of the tree is the same as one of the 419 maximum parsimony trees constructed by the PAUP programME (length: 465 steps, consistency index: 0.6710, retention index: 0.6467). The calmodulin data set included 549 characters with 85 parsimony informative characters. The Neighbour-joining tree shown in Fig. 2 has the same topology as one of the 9 maximum parsimony trees (tree length: 323, consistency index: 0.7585, retention index: 0.6422). The actin data set included 390 characters with 104 parsimony informative characters. The Neighbour joining tree shown in Fig. 3 has the same topology as one of the 312 maximum parsimony trees (tree length: 397, consistency index: 0.6675, retention index: 0.7130). The ITS data set included 501 characters with 26 parsimony informative characters. The Neighbour joining tree shown in Fig. 4 has the same topology as one of the 57 maximum parsimony trees (tree length: 77, consistency index: 0.7532, retention index: 0.7765).

The four Neosartorya isolates representing new species were found to be different from all known species of Aspergillus section Fumigati based on either their β-tubulin, calmodulin or actin gene sequences. However, one of them (NRRL 4179) had identical ITS sequences with N. denticulata (Fig. 4). This isolate was found to be closely related to a clade including N. fennelliae and N. denticulata on all other trees.

Possible synonymies of some species described previously have also been examined during this study. Based on multilocus sequence analyses Hong et al. (2007) discussed the synonymy of N. botucatensis, N. paulistensis and N. takaki with N. spinosa (Raper & Fennell) Kozak. (1972). N. spinosa and the synonyms have roughly circular arrangements of projections on the ascospore convex walls. N. spinosa produces echinulate ascospores with spines ranging from < 0.5 μm up to 5(-7) μm long with verruculose and small triangular projections or sometimes with circularly arranged projections.

N. otanii Takada, Y. Horie & Abliz (2001) was described on the basis of its rapid growth on Czapek and malt extract agars, lenticular ascospores with two widely separated equatorial crests, tuberculate or lobate-reticulate convex surface, and globose to broadly ellipsoidal conidia with a microtuberculate wall. The morphology of N. otanii resembles N. fennelliae, although Takada et al. (2001) reported small differences of the ascospore ornamentation, which was not confirmed in our SEM studies. The β-tubulin gene sequences of N. otanii (GenBank accession numbers AB201363 and AB201362) were identical with N. fennelliae (KACC 42228) (Fig. 5A). These N. fennelliae isolates produced ascospores after mating with the N. fennelliae type strains (data not shown). N. otanii is probably synonymous with N. fennelliae, but mating experiments with N. fennelliae and N. otanii are needed for its confirmation. These experiments could not be carried out because the ex type cultures of N. otanii were not available.

Neighbour-joining trees based on β-tubulin, calmodulin and actin sequence data of Neosartorya spp. showing the relationship of N. primulina, N. quadricincta, N. tatenoi and N. delicata.

Neosartorya primulina Udagawa, Toyaz. & Tsub. (1993) was characterised by its restricted growth on Czapek agar, chalky-buff ascomata, and lenticular ascospores with a very irregular ornamentation composed of several narrow crests and verrucose hemispheres. The ascospore ornamentation and anamorph morphology resembles those of N. quadricincta. Furthermore, the ex type culture (CBS 253.94) of N. primulina showed nearly identical sequences with strains of N. quadricincta for β-tubulin, calmodulin and actin genes (Fig. 5B). N. primulina is reduced to synonymy with N. quadricincta.

Neosartorya delicata H.Z. Kong (1997) was described based on its ellipsoid or nearly clavate vesicles, and ascospores with conspicuous spines, joining one spine to another by fairly prominent ridges and reticulate ornamentation, the ridges spreading to the equatorial crests. This species has identical ascospore morphology with N. tatenoi (Fig. 36), and both taxa were clustered into a clade in three gene trees (99.6 % in β-tubulin, 98.5 % in calmodulin and 97.3 % in actin gene sequences) (Fig. 5B). Therefore, we consider N. delicata as a synonym of N. tatenoi.

Neosartorya nishimurae (Takada ), N. indohii, N. tsurutae (Horie ), N. takakii (Horie ) and N. sublevispora (Someya ) ex-type cultures were not available for this monograph of Aspergillus section Fumigati, and because we could not study them, they are listed as doubtful species.

Morphology and extrolite production

The atypical N. glabra isolate NRRL 4179 (Raper & Fennell 1965) produced asperfuran, aszonalenin, fumigaclavine, viridicatumtoxin, and fumigatins, extrolites common in N. fennelliae, but none of the extrolites produced by N. glabra. However, in contrast with the heterothallic N. fennelliae, this isolate is homothallic. It is closely related to N. denticulata based on phylogenetic analysis of sequence data, although their ascospore ornamentations are strikingly different (Figs. 21, 23). Ascospore ornamentation of NRRL 4179 is similar to that of the heterothallic N. fennelliae (Fig. 22) with equatorial crests much narrower, while N. denticulata has denticulate ascospores without equatorial crests. Isolate NRRL 4179 exhibited 72 % nuclear DNA relatedness to N. fennelliae and only 60 % relatedness to N. glabra isolates (Peterson 1992). This isolate also yielded different mtDNA and SmaI-digested repetitive DNA patterns from those of all the other Neosartorya strains examined (Rinyu ). Hybridisation experiments were also carried out with Neurospora crassa mating type genes (the A idiomorph with about 6 kb flanking sequences, or the a idiomorph flanked by about 2 kb genomic DNA on either side) to the EcoRI digested DNA of several teleomorphic and asexual Aspergillus strains. Hybridisation to a 1.9 kb band was observed for both mating-type strains of N. fennelliae and isolate NRRL 4179 (Rinyu ). Based on these observations, isolate NRRL 4179 seems to be closely related to N. fennelliae strains. These results are in agreement with those found using carbon source utilisation tests and isoenzyme analysis of these strains (Varga ).

Strain NRRL 35723 was isolated from soil in Australia, and produced compounds structurally related to wortmannin, aszonalenin, chromanols, tryptoquivalins and tryptoquivalons. This isolate was markedly different from all other known Neosartorya species in secreting a bluish pigment after 7 d incubation on MEA and CYA plates. The microtuberculate ascospore ornamentation of this isolate is similar to those of N. laciniosa, N. glabra and N. galapagensis (Hong ). However, it grew more slowly on CYA than these species, and phylogenetic data also indicate that this isolate represents a new species.

CBS 112.55 was isolated from garden soil in Adelaide, Australia, and produced compounds similar to wortmannin and aszonalenin and some unique metabolites, while CBS 841.96 was isolated from Podocarpus bark in Papua New Guinea, and produced a compound related to wortmannins and some unique compounds the structures of which have not yet been elucidated (Table 2). The ascospore ornamentations of these isolates were microtuberculate, similarly to those of N. glabra and N. galapagensis. However, both isolates produced cream-coloured colonies on CYA in contrast with N. glabra which produces greyish green colonies. In phylogenetic analysis they were unrelated to any other Neosartorya species, justifying their treatment as new species. We propose four new homothallic and monotypic Neosartorya species; N. ferenczii (NRRL 4179), N. warcupii (NRRL 35723), N. australensis (CBS 112.55) and N. papuensis (CBS 841.96).

Identification

Traditionally the identification of members of section Fumigati were done using the colony patterns and the morphology of the conidiogenous structures, conidia, ascomata and ascsopores. Ascospore ornamentation has been studied by Scanning electron microscopy, but our studies have shown that different species have similar ascospore shape and surface structure. Several species such A. fumigatus, A. novofumigatus, fumigatiaffinis, A. fumisynnematus and A. lentulus show strong morphological resemblance and in the lightmicroscope these species can be difficult to be separated. The anamorphs of Neosartorya udagawae and N. fennelliae also show a similar morphology. Therefore we recommend that for a correct species identification, sequence analysis should be carried out. Our experience with sequencing the calmodin and β-tubulin gen revealed good species delimitation and recognition. All sequences of the ex type cultures of section Fumigati are available from specialised databases and also from GenBank.
