Abstract

The research work was aimed at finding electrophoretic polymorphic bands that can be used as genetic markers to select tomato accessions with heat stress tolerance. An electrophoresis analysis of peroxidases, catalases, superoxide dismutases and total proteins of control samples and those treated at 40oC for 90 minutes was performed in four accessions with different heat tolerance degrees: Nagcarlang, L-103, Campbell-28 and HC 3880. Isoenzymatic patterns of peroxidases and catalases were not affected by heat stress; however, electrophoretic bands of superoxide dismutase isoenzymes showed a reduced activity compared to the control at the heat susceptible accessions Campbell-28 and HC 3880. Also a new band of 100 kDa was observed in all heat stressed genotypes.
