Two Diaporthe species isolated from fruit of Citrus sinensis in China were identified based on morphology and multilocus phylogeny of ITS, tef1, and tub2 gene sequences. The results showed that the two species corresponded to Diaporthe taoicola and D. siamensis, with distinct morphological characteristics and pathogenicity to fruit of C. sinensis.
Two Diaporthe species isolated from fruit of Citrus sinensis in China were characterized based on morphology and multilocus phylogeny of ITS, tef1, and tub2 gene sequences. The phylogeny indicated that the two species match Diaporthe taoicola and D. siamensis. A critical examination of phenotypic characteristics confirmed the phylogenetic results. Diaporthe taoicola was morphologically characterized by producing Alpha conidia with tapering toward both ends. Meanwhile, D. siamensis produced cylindrical or ellipsoidal Alpha conidia with two oil drops. Pathogenicity tests revealed that both species were pathogenic to fruit of C. sinensis. To our knowledge, the two species were firstly reported on Citrus sinensis in China.
