Reclassification of Xanthomonas isolates causing bacterial leaf spot of Euphorbia pulcherrima

Abstract

Bacterial leaf spot of Euphorbia pulcherrima has been reported in many countries. Characterization by polyphasic approaches indicated that the isolates from India, USA and New Zealand could be distinguished based on rep-PCR profiles and gyrB phylogenies, while the Chinese isolates should be ascribed to Xanthomonas axonopodis pv. poinsettiicola. © The Korean Society of Plant Pathology.
