Expression profiling and transcriptional regulation of the SRS transcription factor gene family of common bean (Phaseolus vulgaris) in symbiosis with Rhizobium etli.

ABSTRACT: The SRS/STY transcription factors from the model legumes: Lotus japonicus and Medicago truncatula, are part of regulatory networks that play relevant roles for nodule development during the N-fixing symbiosis with rhizobia. In this work we analyzed the participation of the PvSRS transcription factors from common bean (Phaseolus vulgaris), a most important legume crop, in the symbiosis with Rhizobium etli. Our phylogenetic analysis of SRS TFs across five plant species, including four legumes and Arabidopsis thaliana, identified clades that group SRS proteins that are highly expressed in legume nodules and in Arabidopsis roots. A qRT-PCR expression analysis of the 10 PvSRS in root/nodule of inoculated plants, revealed that all the PvSRS genes are expressed at different stages of the symbiosi
