The osmolyte-producing endophyte Streptomyces albidoflavus OsiLf-2 induces drought and salt tolerance in rice via a multi-level mechanism
文献摘要：
Drought and salinity are major environmental stresses that impair crop growth and productivity world-wide.Improving drought and salt tolerance of crops with microbial mutualists is an effective and envi-ronmentally sound strategy to meet the demands of the ever-growing world population.In the present study,we found that the Streptomyces albidoflavus OsiLf-2,a moderately salt-tolerant endophytic actino-mycete,produced abundant osmolytes,including proline,polysaccharides,and ectoine.Inoculation with OsiLf-2 increased the osmotic-adjustment ability of the rice host by increasing the proline content(by 250.3％and 49.4％)and soluble sugar(by 20.9％and 49.4％)in rice under drought and salt conditions,rel-ative to the uninoculated control.OsiLf-2 increased stress responses in the rice host at the physiological and biochemical levels(photosynthesis efficiency,osmolytes and antioxidant content),and the gene level(osmolytes synthesis,stress-responsive and ion-transport related genes),raising rice yields under both greenhouse and saline-alkaline soil conditions.The use of endophytic actinomycetes offers a promising biotechnological approach to developing stress-tolerant plants.
