Whole-Genome Sequencing and Comparative Genome Analysis of Fusarium solani-melongenae Causing Fusarium Root and Stem Rot in Sweetpotatoes.

ABSTRACT: Sweetpotato (Ipomoea batatas) is the eighth most important crop globally. However, the production and quality of sweetpotatoes are threatened by Fusarium diseases that are prevalent around the world. In this study, a Fusarium species that causes root and stem rot in sweetpotatoes was studied. The pathogenic fungus CRI 24-3 was isolated and sequenced using third- and next-generation sequencing techniques and a 49.6 Mb chromosome-level draft genome containing 15,374 putative coding genes were obtained. Molecular phylogenetic analysis showed that CRI 24-3 was an F. solani-melongenae strain within clade 3 of the F. solani species complex (FSSC). CRI 24-3 showed a relatively high number of virulence factors, such as carbohydrate-active enzymes (CAZymes), pathogen-host interaction (PHI) proteins
