Original Article


A new species of Trichoderma, Trichoderma guizhouense, isolated from soil in Guizhou Province, is described based on morphology and phylogenetic analyses. This species exhibits characteristic Trichoderma morphology but is distinct from related species based on characters of phialides and conidia. Two DNA markers, the translation elongation factor 1 alpha (tef1) and RNA polymerase II subunit b (rpb2) were used for phylogenetic analyses. The correlation between morphological and molecular-based clustering demonstrated two studied isolates are a new species.

Supplement Fig. 1Topology showing the single most parsimonious tree, inferred by combined ITS and tef1 sequences. Sequences from the two genes were combined with a total of 1093 aligned characters. Among them, 230 characters were parsimony-informative. Tree length of 892 steps, consistency index = 0.6177, retention index = 0.5290, Rescaled consistency index = 0.3268, Homoplasy index = 0.3823. Bootstrap values smaller than 50 % are not shown. Thickened branches indicate Bayesian posterior probabilities ≥95 %. The tree was rooted to Trichoderma oblongisporum (JPEG 1733 kb)
