Multigene phylogenetic analyses of the Thelonectria coronata and T. veuillotiana species complexes

Mostrar todas las versiones(3)

Thelonectria is a recently established genus of common and ubiquitous fungi on woody hosts, previously placed in the genus Neonectria. Thelonectria coronata and T. veuillotiana occur sympatrically in tropical, subtropical and temperate regions. Previous taxonomic studies including T. coronata and T....

Chaverri, P. 2012 Thelonectria is a recently established genus of common and ubiquitous fungi on woody hosts, previously placed in the genus Neonectria. Thelonectria coronata and T. veuillotiana occur sympatrically in tropical, subtropical and temperate regions. Previous taxonomic studies including T. coronata and T. veuillotiana suggested these fungi could represent species complexes; however, the morphological features used to define species exhibited few differences useful for testing this hypothesis. To assess the status of T. coronata and T. veuillotiana, phylogenetic analyses of six genomic regions were combined with a morphological examination of specimens. A multigene phylogeny reconstructed with maximum parsimony, maximum likelihood and Bayesian approaches identified five phylogenetic groups in T. coronata and six in T. veuillotiana. As is common for cryptic species, unequivocal diagnostic morphological characters could not be identified; however, average values of morphological traits correspond to the phylogenetic groups. An increased number of nonsynonymous/ synonymous substitutions in the b-tubulin gene and a decreased or absent production of conidia were detected within the T. coronata complex, possibly indicating the homothallic nature of these isolates. T. coronata and T. veuillotiana and related species are described and illustrated here; a dichotomous key to all species is provided. © 2012 by The Mycological Society of America. Fil:Capdet, M.
