Morphology, Phylogeny and Pathogenicity of Colletotrichum menglaense sp. nov., Isolated from Air in China

Abstract

A new species, Colletotrichum menglaense, isolated from air in Mengla, Xishuangbanna, Yunnan Province, China, was characterized and described combining morphological characteristics and multigene phylogenetic analysis. Morphologically, it is characterized by oblong, sometimes slightly constricted, micro-guttulate conidia and simple obovoid to ellipsoidal appressoria. Phylogenetic analysis of the ITS, ACT, CHS, and GAPDH sequences showed that C. menglaense belongs to the C. gloeosporioides complex. The pathogenicity of C. menglaense on fruits of several crop plants, including strawberry, orange, grape, tomato, and blueberry, was tested and confirmed by the re-isolation of C. menglaense.

Novel Pathogen–Plant Host Interaction: Colletotrichum jiangxiense and Fraxinus americana L. (White Ash) in a Sentinel Garden in China

“…Various genetic loci, especially within species complexes, have been employed to obtain comprehensive molecular information for species differentiation [25]. Additional loci, including ACT, CAL, CHS-1, GAPDH, and TUB2 genes, have been used for the Colletotrichum species complex [26,27]. In this study, we utilized a multi-locus phylogenetic approach based on those sequences mentioned above, coupled with the morphological characteristics.…”

Endophytic Colletotrichum Species from Aquatic Plants in Southwest China

“…The genus Colletotrichum was established by Corda (1831) with C. lineola as the type species and is the sole genus in the family Glomerellaceae (Glomerellales, Sordariomycetes, Ascomycota) [30][31][32][33][34]. Colletotrichum species are globally distributed and are important plant and human pathogens [35][36][37][38][39][40], endophytes [41][42][43][44], and saprobes [43,45,46]. However, the taxonomy of Colletotrichum species has proven to be challenging.…”
