  • Cassava bacterial blight（ CBB） is a destructive disease of cassava（ Manihot esculenta） and is caused by Xanthomonas axonopodis pv manihotis,Xam. This disease had invoked a serious damage to cassava industry in other countries. The pathogen of the CBB was isolated from the infected leaves collected from cassava varieties SC8 and SC5 in Qiongzhong County,Hainan,and then purified for morphological observation,pathogenecity assay and biochemical assay. This pathogen was also identified by using 16 S r DNA gene sequence analysis. The results showed that the isolated pathogen was Xanthomonas axonopodis.

Abstract: Cassava bacterial blight（ CBB） is a destructive disease of cassava（ Manihot esculenta） and is caused by Xanthomonas axonopodis pv manihotis,Xam. This disease had invoked a serious damage to cassava industry in other countries. The pathogen of the CBB was isolated from the infected leaves collected from cassava varieties SC8 and SC5 in Qiongzhong County,Hainan,and then purified for morphological observation,pathogenecity assay and biochemical assay. This pathogen was also identified by using 16 S r DNA gene sequence analysis. The results showed that the isolated pathogen was Xanthomonas axonopodis.
