Abstract

A collection of fungal isolates obtained from crop plants, specifically grapevine and blueberry, in Peru were characterised through morphological and DNA sequence analyses of the nuclear ribosomal internal transcribed spacer (ITS), beta-tubulin () and translation elongation factor 1-alpha (α) regions. Isolates produced monomorphic and dimorphic conidiophores typical of members of the genus . Single- and multi-locus gene phylogenies confirmed the isolates as representing members of the genus , more closely related to species in the subgenus . In phylogenetic analyses the isolates grouped in two separate clades, one corresponding to the species and the other one distinct from all known species of the genus . These isolates are recognized as representing a novel species species for which the name is proposed.

摘要

从秘鲁的农作物,特别是葡萄藤和蓝莓中获得的一组真菌分离株,通过对核糖体核糖体内转录间隔区(ITS)、β-微管蛋白()和翻译延伸因子1-α(α)区域进行形态学和DNA序列分析来进行表征。分离株产生了该属成员典型的单态和双态分生孢子梗。单基因座和多基因座系统发育分析证实这些分离株代表该属的成员,与亚属中的物种关系更密切。在系统发育分析中,分离株分为两个独立的分支,一个对应于物种,另一个与该属所有已知物种不同。这些分离株被认为代表一个新物种,为此提出了名称。
