【摘要】 |
|
Drought is a major environmental factor that limits the yield of rice dramatically. Upland rice is now regarded as a promising rice cultivar in water saving agriculture. Two varieties of upland rice Zhonghan 3 and IR29 were used to compare the physiological and proteomic responses to hyper-osmotic stress induced by 15% polyethyleneglycol (PEG) at the reproductive stage. Osmotic stress affected the growth development and caused the loss of production especially the grain yield. IR29 was more tolerant to PEG than Zhonghan 3 as shown by less yield loss under osmotic stress conditions. Comparative proteomic analysis of the panicle suggested that the up-regulation of glycolysis related proteins and defense proteins may contribute to the better osmotic tolerance in IR29. |
