Genome Sequence Resource for Colletotrichum gloeosporioides, an Important Pathogenic Fungus Causing Anthracnose of Dioscorea alata

Anthracnose disease is one of the most important diseases of Dioscorea alata and many other food yams, which is caused by Colletotrichum gloeosporioides fungus from the Glomerellaceae family of the Sordariomycetes class. In the present study, a C. gloeosporioides starin named CgDa01 was isolated from D. alata, and its genome was sequenced based on Oxford Nanopore technology (ONT) and the Illumina sequencing platform. The high-quality genome of CgDa01 was assembled with a 62.78 Mb genome size and 15,845 predicted protein-coding genes. The proteins of predicted genes were annotated using multiple public databases, including the nonredundant protein database, the InterProScan databases, and Kyoto Encyclopedia of Genes and Genomes. Among the annotated protein-coding genes, 55 were predicted as potential virulence genes by the fungal virulence factor database. The C. gloeosporioides CgDa01 genome assembly described in this study can serve as a resource for better understanding the pathogenic mechanism of C. gloeosporioides on yam hosts.
