Genome Sequence Resource for Colletotrichum viniferum, the Cause of Grapevine Ripe Rot in China

Abstract

Grape ripe rot is an important disease that has seriously damaged the yield and quality of grape worldwide. The disease is caused by Colletotrichum viniferum, a hemibiotrophic fungus that belongs to the Glomerellaceae family of Sordariomycetes class. Here, this work presents the genome of C. viniferum stain CvYL2a from grape based on Illumina HiSeq 2500 and PacBio RS II. The high-quality genome consists of 70 contigs with a 73.41 Mb genome size and encodes 14,668 protein-coding genes. These genes were annotated using Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, EuKaryotic Orthologous Groups, Non-redundant Protein, and Swiss-Prot database. In addition, we identified a series of genes involved in pathogenicity including 909 carbohydrate-active enzymes, 67 secondary metabolite gene clusters, and 307 Cytochrome P450 enzymes. This genome sequence provides a valuable reference for the research on grape-C. viniferum interactions, the pathogenesis of C. viniferum, and comparative genome analyses.
