Résumé
Abiotic stresses like drought and salinity are one of the most limiting factors for stable crop production worldwide. In recent years, molecular-based applications are being applied to solve these problems. In this regard, the molecular mechanisms of transcription factors have gained attention and gene expression studies have become indispensable to understand the underlying molecular and morphological (such as RWC) mechanisms. Salicylic acid (SA) acts as an endogenous signaling molecule that induces abiotic stress tolerance in plants. Transcription factors (TF) have important roles in regulating a variety of biological processes like salicylic acid dependent resistance of plants to stress. In this study, the expression levels of YABBY and DOF genes in the 2 different beans (Phaseolus vulgaris L.) variety (Yakutiye-98, Zülbiye) were investigated under drought stress conditions and also the effects of salicylic acid application on the plants under drought stress have been studied at gene expression level. Relative water content (RWC) and other morphological variations, as well as the changes observed in expression levels of the transcription factors in comparison with salicylic acid application under drought stress, showed the effect of stress and hormone application and also revealed the importance of the transcription factors. The current study gives information about the expression patterns of the transcription factors YABBY and DOF in common bean. Exposed to drought stress and the effect of salicylic acid on this pattern. The study will shed light to the future studies about the mechanisms of transcription factors and related future studies about common bean.
