ABSTRACT

The changes in protein profile of extract of Ulva reticulata grown fruit of Cyamopsis tetragonoloba was analysed using Sodium Dodecyl Sulphate Poly Acrylamide Gel Electrophoresis (SDS-PAGE). Seaweed extract (Seaweed Extract) treatment was found to stimulate the synthesis of polypeptides 125, 122, 120, 35.3, 7.9 and 6.8 KDa of high and low molecular weight which were not found in control. In control, the polypeptides visualized were 107, 92, 88, 77, 75, 54, 48, 35.6 and 35.4 KDa. Though some differences were observed both in treated and control plants, polypeptides of 92, 88 and 75 KDa were expressed both in treated and control plants with variation in intensity. These results indicate that SWE application as foliar spray increased protein level in fruits by stimulating the synthesis of more polypeptides.
