Proteomics Study in Rice Responses and Tolerance to Salt Stress

Abstract Rice (Oryza sativa) growth and productivity is severely affected by salinity. Under salt stress, the dynamic regulation of proteins in different functional groups plays a major role in different signaling pathways. Differentially expressed proteins in rice roots and shoots serve as marker groups for salt tolerance in rice. Rice roots function as the primary site for salinity perception, transmitting salt signals to the shoots for proper salt response and adaptation of the entire plant. A comprehensive understanding of the mechanisms protecting rice during salt stress through the help of proteomics will aid in the development of salt tolerant cultivars.
