説明
<jats:title>Abstract</jats:title><jats:p>Species of the fungal genus <jats:italic>Colletotrichum</jats:italic> are among the most devastating pathogens of agricultural crops in the world. Based on DNA sequence data (ITS, <jats:italic>GAPDH</jats:italic>, <jats:italic>CHS-1</jats:italic>, <jats:italic>ACT</jats:italic>, <jats:italic>TUB2</jats:italic>) and morphology, we revealed <jats:italic>Colletotrichum</jats:italic> isolates infecting the oil crop <jats:italic>Perilla frutescens</jats:italic>, commonly known as shiso, to represent a previously unknown species of the <jats:italic>C. destructivum</jats:italic> species complex and described it as <jats:italic>C. shisoi</jats:italic>. We found that <jats:italic>C. shisoi</jats:italic> appears to be able to adopt a hemibiotrophic lifestyle, characterised by the formation of biotrophic hyphae followed by severe necrotic lesions on <jats:italic>P. frutescens</jats:italic>, but is less virulent on <jats:italic>Arabidopsis</jats:italic>, compared to its close relative <jats:italic>C. higginsianum</jats:italic> which also belongs to the <jats:italic>C. destructivum</jats:italic> species complex. The genome of <jats:italic>C. shisoi</jats:italic> was sequenced, annotated and its predicted proteome compared with four other <jats:italic>Colletotrichum</jats:italic> species. The predicted proteomes of <jats:italic>C. shisoi</jats:italic> and <jats:italic>C. higginsianum</jats:italic>, share many candidate effectors, which are small, secreted proteins that may contribute to infection. Interestingly, <jats:italic>C. destructivum</jats:italic> species complex-specific secreted proteins showed evidence of increased diversifying selection which may be related to their host specificities.</jats:p>
