High-Quality Genome Resource of the Pathogen of Botryosphaeria dothidea Causing Kiwifruit Soft Rot

Abstract

Kiwifruit soft rot caused by the fungal pathogen Botryosphaeria dothidea is a serious disease in kiwifruit-growing regions worldwide. In this study, we reported the high-quality genome sequence of the highly virulent B. dothidea strain PTZ1 using PacBio Sequel techniques. In total, 100.87 million clean reads with mean read length of 9,871 bp were obtained. De novo assembly resulted in 28 contigs with a total size of 44.45 Mb. The GC content of the genome was 54.59%. Furthermore, genes related to specific virulence of the strain were identified, including 259 fungal cytochrome P450s, 550 carbohydrate-active enzymes, 860 secretory proteins, and 1,182 pathogen–host interactions related proteins. The genome is a useful resource to serve as a reference to facilitate the analysis of B. dothidea isolates and comparative genomic studies of the necrotroph pathogens.
