Four commercial sugarcane varieties differing in their maturity were studied for the protein profiles under control (50% ASM), moisture stress of 40% ASM (mild stress) and 30 % ASM (severe stress). Both qualitative and quantitative differences were observed. Total soluble proteins content in leaves significantly increased at both 40% ASM levels (21.05 and 27.19%) and 30% (27.15 and 43.44%) as compared to 50% ASM level at 60 and 90 DAP, respectively. Severe stress of 30% ASM levels caused formation of new protein band of MW 18.56, 13.46, 31.6 and 36.6 kDa in leaves of variety Co 0238. In CoJ 64, one new polypeptide band of MW 38.5 kDa appeared and two polypeptide bands of MW 13.6 and 18.56 kDa disappeared. Variety CoS 767 showed the presence of four new band of 13.46, 15.6, 18.56 and 38.2 kDa. Likewise in variety CoH 128 two new polypeptide bands of MW 25.2 and 26.8 kDa appeared and 4 band of MW 13.46, 15.6, 18.17 and 54.6 kDa disappeared at 30% and 40% ASM levels. Appearance of new polypeptide(s) or their disappearance might be related to the genotypic stress tolerance or sensitivity.
