So far, little has been achieved in characterizing gene products that may impart resistance against various abiotic stresses. We have analyzed various proteins in rice that are specifically modulated to respond to salinity (NaCl), high and low temperatures, and drought, by using one- and two-dimensional protein gel electrophoresis coupled to highly resolutive silver staining and radiolabeling. By subjecting proteins to various stresses and to abscisic acid, we have been able to distinguish polypeptides that accumulate in response to a specific stress stimulus from those that accumulate in response to a number of different stress stimuli. Data on the expression pattern of three high-molecular weight (110, 104, and 90 kDa) stress proteins of rice are presented in this paper. Further, we compare 104- and 90-kDa stress proteins in salt-sensitive (Basmati 370) and salt-tolerant (CSR10 and CSR19) rice cultivars
