摘要：

Xanthomonas oryzae pv. oryzae is the causative agent of bacterial blight of rice and causes severe harvest loss and challenges to a stable food supply globally. In this study, a hypervirulent strain, LN4, compatible in rice varieties carrying Xa3, Xa4, xa13, and xa25 resistance genes, was used to generate DNA for nanopore sequencing. After assembly, the genome comprises a single chromosome of 5,012,583 bp, consisting of a total of 6,700 predicted coding sequences. Seventeen transcription activator-like effectors (TALEs) were encoded in the genome, of which two (Tal7 and Tal6c) were major TALEs. The approach and genome data provide information for the discovery of new virulence effectors and understanding of the virulence mechanism of TALEs in rice.
