- Abstract
The expression of malate dehydrogenase, superoxide dismutase and polygalacturonase-inhibiting protein was investigated in common bean plants inoculated with Xanthomonas hortorum pv. pelargonii as a non-host pathogen and X. axonopodis pv. phaseoli as a host pathogen. In comparison with inoculated plants with a host pathogen, more expression of malate dehydrogenase and superoxide dismutase was observed in treatments of non-host pathogen. The maximum expression of the genes was recorded 48 h post inoculation. Malate dehydrogenase and superoxide dismutase play crucial roles in incompatible plant-pathogen interaction. No significant difference was detected in expression of polygalacturonase-inhibiting protein in inoculated plants with host or non-host pathogen compared to control in any time points. In the absence of polygalacturonase that acts as an elicitor, polygalacturonase-inhibiting protein are not expressed.
