Molecular cloning and characterization of salt overly sensitive gene promoter from Brassica juncea (BjSOS2)

Salt Overly Sensitive (SOS) pathway comprising SOS1, SOS2 and SOS3 genes has been recognized as the key mechanism controlling ion homeostasis under salinity stress. SOS2 component of this pathway encodes a serine/threonine protein kinase that together with SOS3 activates downstream Na+/H+ antiporter SOS1, reestablishing cellular ion homeostasis under salinity stress. In the present study, we have found that the transcript levels of BjSOS2 are...
