- Abstract
In 2014, Pestalotiopsis was divided into three genera based on molecular phylogenetic and morphological analyses, but the study did not include Pestalotiopsis longiseta and Pseudopestalotiopsis theae (syn. Pestalotiopsis theae), which had been identified as the pathogens causing gray blight of tea in Japan. In the present study, we thus reanalyzed 13 isolates of Pestalotiopsis sensu lato from tea leaves that we collected from Shizuoka Prefecture and 11 strains from nine districts in Japan that had been deposited in NARO Genebank, Japan as P. longiseta, causal agents of gray blight of tea based on morphology and phylogenetic analysis of the internal transcribed spacer region of ribosomal DNA and β-tubulin and translation elongation factor 1-α gene regions. All isolates were found to belong to the genus Neopestalotiopsis, and the pathogenic isolates were closely genetically related to N. asiatica, N. australis, N. chrysea, N. clavispora, N. ellipsospora, or N. samarangensis. However, the conidial morphology resembled or partially overlapped with those of P. longiseta. We were unable to identify the isolates and strains at species level due to taxonomic confusion and repudiate the reports of P. longiseta and P. theae as pathogens of gray blight disease. We confirmed the pathogenicity of 17 isolates and strains (all 13 Shizuoka isolates and four strains from NARO Genebank) and propose to add Neopestalotiopsis spp. as a pathogen of gray blight.
