Complete Genome Resource of a Hypervirulent Xanthomonas oryzae pv. oryzae Strain YNCX Isolated from Yunnan Plateau Japonica Rice

Abstract

Xanthomonas oryzae pv. oryzae (Xoo), the causal agent of bacterial leaf blight (BLB), is one of the most destructive bacterial pathogens in rice production worldwide. Although several complete genome sequences of Xoo strains have been released in public databases, they are mainly isolated from low-altitude indica rice cultivating areas. Here, a hypervirulent strain, YNCX, isolated from the high-altitude japonica rice-growing region in Yunnan Plateau, was used to extract genomic DNA for PacBio sequencing and Illumina sequencing. After assembly, a high-quality complete genome consisting of a circular chromosome and six plasmids was generated. The genome sequence of YNCX provides a valuable resource for high-altitude races and enables the identification of new virulence TALE effectors, contributing to a better understanding of rice-Xoo interactions.
