Abstract

MADS-box genes are known to play important roles in diverse aspects of growth/devolopment and stress response in several plant species. However, no study has yet examined about MADS-box genes in P. vulgaris. In this study, a total of 79 PvMADS genes were identified and classified as type I and type II according to the phylogenetic analysis. While both type I and type II PvMADS classes were found to contain the MADS domain, the K domain was found to be present only in type II PvMADS proteins, in agreement with the literature. All chromosomes of the common bean were discovered to contain PvMADS genes and 17 paralogous gene pairs were identified. Only two of them were tandemly duplicated gene pairs (PvMADS-19/PvMADS-23 and PvMADS-20/PvMADS-24), and the remaining 15 paralogous gene pairs were segmentally duplicated genes. These duplications were found to play an important role in the expansion of type II PvMADS genes. Moreover, the RNAseq and RT-qPCR analyses showed the importance of PvMADS genes in response to drought stress in P. vulgaris.
