摘要:
全球盐渍化土壤严重威胁农业可持续发展,微生物改良技术作为一种经济有效的土壤修复方法,成为全球研究热点之一。本文总结了克雷伯氏菌(Klebsiella spp.)作为植物根际细菌的耐盐和促生特性；回顾了其提高作物耐盐性和促生效果的研究进展。阐明了克雷伯氏菌可通过协同调控抗氧化酶活性、积累渗透调节物质、维持离子平衡及调控信号转导途径,显著提升水稻、小麦、棉花等作物的耐盐性；同时通过固氮、溶磷、解钾等营养转化作用,以及调控生长素合成与降低乙烯(ET)合成等方式,有效改善盐胁迫下多种作物的种子萌发、生物量积累及产量形成；指出当前农业生产中克雷伯氏菌的应用仍面临诸多挑战,包括菌株的环境适应性差、遗传稳定性不足,以及潜在生态风险等；未来需结合多组学技术解析菌群互作机制,挖掘并改造高效功能基因与工程菌株,定向研发新型微生物肥料,从而推动其在盐碱地生物改良与修复领域的产业化应用。
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 summarizes 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 activities, accumulating osmotic adjustment substances, maintaining ion balance, and modulating signal transduction pathways. Meanwhile, through nutritional transformation effects such as nitrogen fixation, phosphate solubilization, and potassium release, as well as by regulating auxin synthesis and reducing ethylene (ET) synthesis, it effectively improves seed germination, biomass accumulation, and yield formation 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.
