Abstract
As sessile plants have developed adaptive strategies to cope with environmental stress. The understanding of plants responses to their external environment is of importance with respect to basic research. It is also an attractive target for improving the performance of crop plants under stress conditions. This investigation showed that PRF1 expression in watermelon calli exposed to salinity was reduced, in contrast, the PRF1 expression was increased by zinc. Calli fresh weight exposed to 150 mM NaCl and 800 mM ZnSO4 . 7H2O were decreased by 69% and 76%, respectively. Peroxidase activity was increased in salinity and zinc stressed calli. At 150 mM NaCl-stressed calli had a peroxidase activity 2.3 times higher than unstressed calli.
