abstract the ability to monitor particular microorganism in an environment is a difficult task. many genes permit the differentiation of strains by conferring production of unique phenotypes such as bioluminescence [marine bacterial luciferase (luxab)]. therefore, lux-ab gene was cloned into two endemic plant pathogens pseudomonas syringae and ralostonia solanacearum by electrotransformation. l...

Infection of host plants by Pseudomonas solanacerum results in wilting, which is thought to be due largely to the occlusion of xylem vessels by the P. solanacearum extracellular polysaccharide (EPS) that primarily consists of N-acetylgalactosamine (GalNAc). By means of Tn3 mutagenesis, we identified a 6.5-kb gene cluster that contains five complementation units required for EPS production and v...

Bacterial wilt disease caused by Ralstonia solanacearum (Smith) Yabuuchi is one of the most important bacterial diseases in world. This study aimed to test some chemical compounds such as bactericides that were applied control under artificial inoculation conditions and their effects on yield potatoes greenhouse conditions.In vitro, tested (Cefalexin, Gentamycin, Copper sulphate) inhibit growth...
