Identification of cassava bacterial blight-causing Xanthomonas axonopodis pv. manihotis based on rpoD and gyrB genes

Abstract

Cassava (Manihot escalenta Crantz) is one of the most important crops in Vietnam for providing food, starch sources, and raw materials for the production of bio-ethanol and other purposes. Cassava bacterial blight (CBB) disease, caused by Xanthonomas axonopodis pv. manihotis (.Xam), is one of the most important factors affecting cassava production in Vietnam. This is the first confirmed identification of the causal pathogen of CBB disease in Vietnam using molecular tools, and this method is a reliable tool for the detection and identification of other plant bacterial pathogens.
