Diaporthe nobilis, a new record on Camellia sinensis in Guizhou Province, China

[摘要] One Diaporthe strain was isolated from diseased leaves of Camellia sinensis in Guizhou Province. It is characterized by the production of two types conidia (a, b-conidia). Morphologically the species is very similar to Phomopsis laurella (syn. Diaporthe nobilis) in producing cylindrical or ellipsoidal a-conidia with two oil drops. Phylogenetic analysis of combined ITS, β-tubulin and tef1 sequence data shows that these strains are placed in D. eres species complex. Critical examination of the phenotypic characters indicated that this strain represents Diaporthe nobilis, a new record in Camellia sinensis.
