However, little is known about the population structure of this organism in Guangxi Zhuang Autonomous Region, South China. Here, pathotypic and DNA fingerprint analyses were conducted to characterize the isolates of <jats:italic>Xoo<\/jats:italic> collected from rice leaves in five districts of the region from 2013 to 2016. Their pathogenicity was tested by leaf clipping, and the DNA fingerprints were analyzed by repetitive sequence\u2010based polymerase chain reaction and endogenous insertion sequence element\u2010based polymerase chain reaction assays using the repetitive extragenic palindromic sequence and enterobacterial repetitive intergenic consensus primers, respectively. Pathogenicity assays of 70 representative isolates were conducted using a series of near\u2010isogenic lines and two new pathotypes were identified. All the pathotypes were found to be incompatible with <jats:italic>xa5<\/jats:italic> and <jats:italic>Xa7<\/jats:italic>. One pathotype was virulent to <jats:italic>Xa14, Xa21<\/jats:italic>, and <jats:italic>Xa23<\/jats:italic>, whereas another virulent to <jats:italic>Xa21<\/jats:italic> and <jats:italic>Xa23<\/jats:italic>, but incompatible with <jats:italic>Xa14<\/jats:italic>. A dendrogram generated for the data sets obtained from DNA fingerprinting suggested the prevalence of high genetic diversity of <jats:italic>Xoo<\/jats:italic> throughout Guangxi, and no association between the molecular haplotypes and pathotypes was identified.<\/jats:p>","DOI":"10.1002\/jobm.201900354","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T07:29:02Z","timestamp":1569223742000},"page":"1082-1091","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Virulence
