克雷伯氏菌对作物耐盐性的提高及促生效果
Enhancement of crop salt tolerance and growth promotion by Klebsiella spp.
摘要
Abstract
Global salinized soil seriously threatens the sustainable development of agriculture.Microbial remediation technology,as a cost-effective bioremediation method,has become one of the research hotspots worldwide.This article sum-marizes the salt tolerance and growth promoting properties of Klebsiella spp.as rhizosphere bacteria,reviews the research progress in enhancing crop salt tolerance and growth-promoting effects,and clarifies that Klebsiella spp.can significantly improve the salt tolerance of crops such as rice,wheat,and cotton through synergistically regulating antioxidant enzyme ac-tivities,accumulating osmotic adjustment substances,maintaining ion balance,and modulating signal transduction path-ways.Meanwhile,through nutritional transformation effects such as nitrogen fixation,phosphate solubilization,and potassi-um release,as well as by regulating auxin synthesis and reducing ethylene(ET)synthesis,it effectively improves seed germination,biomass accumulation,and yield forma-tion of various crops under salt stress.Furthermore,this paper points out that the application of Klebsiella in current agricultural production still faces many challenges,including poor environmental adaptability of strains,insufficient genetic stability,and potential ecological risks.In the future,it is necessary to combine multi-omics technologies to decipher the mechanisms of microbial interactions,mine and engineer efficient functional genes and engineered strains,and directionally develop novel microbial fertilizers,thereby promoting their industrial application in the biological improvement and remediation of saline-alkali land.关键词
