AP2/EREBP Pathway Plays an Important Role in Chaling Wild Rice Tolerance to Cold Stress

Cold stress is the main factor limiting rice production and distribution. Chaling wild can survive in cold winters. AP2/EREBP a known transcription family associated with abiotic stress. We identified members of rice, maize, Arabidopsis, conducted collinearity analysis gene analysis. used Affymetrix array technology to analyze expression genes cultivated cultivar Pei’ai64S, which sensitive cold. According GeneChip results, levels were different from those Pei’ai64S; increase rate 36 was higher than that Pei’ai64S. Meanwhile, MYC elements for Os01g49830, Os03g08470, Os03g64260 had promoter sequences, resulting high these under low-temperature conditions. Furthermore, we analyzed upstream downstream studied conservation genes. found factors more conserved, indicating may be important regulating pathway significantly increased recombinant inbred lines Nipponbare crossing These results suggest signaling plays an role tolerance
