PROTEIN PROFILE OF CLUSTERBEAN [CYAMOPSIS TETRAGONOLOBA (L.)TAUB.] GENOTYPE UNDER SALINITY STRESS

Abstract

Clusterbean [Cyamopsis tetragonoloba (L.) Taub.] genotype HG-884 seeds were grown under chloride dominated salinity levels (0, 4, 8, 12, 16dSm-1 ). Radicle and plumule proteins profile was analyzed by SDSPAGE. In SDS-PAGE the protein profile of radicle of HG-884 genotype showed the de novo synthesis of three, (79.45, 72.46 and 29.86 kDa) one (59.58 kDa) and one (7.50 kDa) protein bands at 4, 8 and 12 dSm-1 level of salinity respectively observed and at 16 dSm-1 level protein bands remain the same as 12 dSm-1 level. In plumule the de novo synthesis of three (92.28, 79.45 and 60.96 kDa) one (15.30 kDa) and one (7.50 kDa) protein bands at 4, 8 and 12 dSm-1 salinity level respectively was observed and at 16 dSm-1 level proteins bands remains the same as 12 dSm-1 level.
