摘要： Colletotrichum fructicola, one of the dominant pathogens isolated from the main tea region in China, causes leaf spot in mature leaves of tea plants, affecting their growth and yield. Here, we present the draft whole-genome sequence of the C. fructicola strain SX-6 previously used for morphological and transcriptomic analyses. The assembly consists of 510 contigs with an estimated genome size of 56.8 Mb. A total of 15,243 predicted protein-coding genes in the SX-6 genome were annotated using NR, Swiss-Prot, KEGG, KOG, TCDB, GO, PHI, DFVF, P450, SignalP and CAZy databases. We identified 833 carbohydrate-active enzymes, 1803 secreted proteins, 79 secondary metabolite gene clusters and 576 fungal virulence factors that may be involved in the pathogenicity of this fungus. Comparative genome analyses with 25 Colletotrichum species revealed their evolutionary relationships via a constructed phylogenetic tree and identified four gene families whose genes were significantly more abundant in strain SX-6. The resulting assembly will provide a valuable resource for further research on the gene functions of C. fructicola.
