Abstarct: Aerobic mextabolisms, including photosynthesis and respiration, used to be considered as the
sole sources of reactive oxygen species (ROS) generation.It is known for quite some time that
plants actively produce these molecules, which may control many different physiological
processes such as abiotic and biotic stress response, and systemic signaling. Common
bacterial blight of bean caused by Xanthomonas axonopodis pv. phaseoli (Xap); is a sever
and devastating disease in both temperate and tropical production zones. It causes yield losses
by about 40%. Cellular responses of bean to Xap baxsed on transcxript analysis of enzymes
involved in both ROS production and scavenging were analyzed. Inoculated leaves with Xap
were used to study the transcxript changes of the genes via RT-PCR. NADPH Oxidase and
APX inclined significantly at 12 h post inoculation (hpi) followed by a sharp increase at 24
hpi. SOD and MDHAR was continuously rocketed. In contrast, CAT exxpression showed an
enhancement at 12 hpi and a decrease at later stage .
