A Salt Overly Sensitive Pathway Member from Brassica juncea BjSOS3 Can Functionally Complement ΔAtsos3 in Arabidopsis.

ABSTRACT:

Background

Salt Overly Sensitive (SOS) pathway is a well-known pathway in arabidopsis, essential for maintenance of ion homeostasis and thus conferring salt stress tolerance. In arabidopsis, the Ca2+ activated SOS3 interacts with SOS2 which further activates SOS1, a Na+/H+ antiporter, responsible for removing toxic sodium ions from the cells. In the present study, we have shown that these three components of SOS pathway, BjSOS1, BjSOS2 and BjSOS3 genes exhibit differential expression pattern in response to salinity and ABA stress in contrasting cultivars of Brassica. It is also noticed that constitutive expression of all the three SOS genes is higher in the tolerant cultivar B. juncea as compared to the sensitive B. nigra. In silico interaction of BjSOS2 and BjSOS3 has been reporte
