Whole-Genome Sequence of Colletotrichum brevisporum Causing Anthracnose on Papaya (Carica papaya)

Abstract

Colletotrichum spp. are the causal agents of papaya anthracnose, which seriously affects the quality and economic value of papaya fruits. Among them, Colletotrichum brevisporum is a new and important causal pathogen of anthracnose in papaya. The infection mechanisms of C. brevisporum are still unclear, and the genome sequence of C. brevisporum has not been released. In order to systemically explore the interaction between papaya and C. brevisporum, we sequenced the whole genome of the C. brevisporum strain C1, which was isolated from an infected papaya fruit in Guangdong Province, China. The assembly consists of 18 scaffolds with a genome size of 62.66 Mb. Furthermore, we identified genes that may be associated with pathogenicity, such as carbohydrate-active enzymes, secreted proteins, and secondary metabolite gene clusters. This genome resource will provide a valuable resource for future studies on the pathogenesis of C. brevisporum and comparative genomic analyses of the Colletotrichum genus.
