| 英文摘要 | alginate oligosaccharides (aos) prepared from degradation of alginate is a potent plant elicitor. hydroponic experiments were carried out to investigate the mechanism of aos on improving triticum aestivum l resistant ability to drought stress. drought model was simulated by exposing the roots of wheat to polyethylene glycol-6000 (peg-6000) solution (150 g l-1) for 4 days and the growth of wheat treated with peg was significantly decreased. however, after aos application, seedling and root length, fresh weight and relative water content of wheat were increased by 18%, 26%, 43% and 33% under dehydration status compared with that of peg group, respectively. moreover, the antioxidative enzymes activities were obviously enhanced and malondialdehyde (mda) content was reduced by 37.9% in samples treated by aos. additionally, the drought resistant related genes involved in aba signal pathway, such as late embryogenesis abundant protein 1 gene (lea1), psba gene, sucrose non-fermenting 1-related protein kinase 2 gene (snrk2) and pyrroline-5-carboxylate synthetase gene (p5cs) were up-regulated by aos. our results suggested that aos might regulate aba-dependent signal pathway to enhance drought stress resistance of wheat during growth period.
