Abstract

Comparison of adenylate kinase activities in rice seedlings (Oryza sativa L. cv. Yamahoushi) that had been grown in the absence or presence of NaCl indicated that NaCI apparently stimulated enzyme activities in roots of this salt-sensitive japonica rice cultivar. Such stimulation of enzyme activities is not limited to a specific portion of root tissues. Furthermore, NaCl-induced adenylate kinase activation was confirmed in the indica rice cultivar IR 28 susceptible to salinity-stress, but not in the NaCl-tolerant indica cultivar Nona Bokra. Thus in salt sensitive rice plants, adenylate kinase may play some role in the adenylate homeostatis at the early stages of rice seedling growth subjected to salt-stress.
