Physiological Responses of Common Bean Genotypes to Drought Stress

Drought compromises edible vegetable production worldwide, including common bean (Phaseolus vulgaris L.) an economically important crop that is highly dependent on optimum rainfall or abundant irrigation. In the present study, phenotypic data of 26 Bulgarian mutant lines and cultivars subjected to drought stress has been summarized, reaction was evaluated by chlorophyll fluorescence proteomics approaches. Several basic photosynthetic parameters were examined during treatment evaluate response, showed different responses. Subsequently, a relationship found between productivity performance with expression ribulose-1,5-bisphosphate carboxylase through comparative 2D-gel based electrophoresis; accumulation well-known stress-related proteins markers dehydrins small heat shock established as well. These findings support further selection tolerant for sustainable agriculture.
