Functional analysis and expressional regulation of wxoE and wxoF in lipopolysaccharide (lps) biosynthesis gene cluster I of Xanthomonas oryzae pv. oryzae

► wxoE and wxoF genes of X. oryzae pv. oryzae are required for pathogenecity. ► The genes effect in LPS O-antigen and EPS biosynthesis. ► WxoE has activity cystachionine lysase. ► WxoF is located in membrane and is homologous to methyltransferases. ► The lps genes involving wxoE and wxoF in cluster I are cotranslated in an operon.
