A full-length cDNA of a new serine/threonine (Ser/Thr) protein kinase gene, designated as BnSOS2 (GenBank Acc. No.AY310413), was cloned from Brassica napus by rapid amplification of cDNA ends (RACE). The fulllength cDNA of BnSOS2 was 1779 bp and contained a 1539-bp open reading frame encoding a protein of 512 amino acids. Homology analysis shows that BnSOS2 strongly resembles other Ser/Thr protein kinase genes, and that its putative protein belongs to a typical Ser/Thr kinase family. Northern blot analysis reveals that BnSOS2 is salt-inducible. Our results indicate that BnSOS2 is a new member of the plant SOS2 gene family, which may play an important role in salt tolerance of plants.
