Abstract As one of the major non–biological stresses, soil salinity negatively affects agricultural productivity, microbial communities, and agricultural economics in impacted areas and is a significant agrarian problem worldwide that has expanded in the last few decades. The use of glycophytes (salt–sensitive plants) is the primary limitation to such an agricultural approach. However, halophytes, which are proficient at obtaining essential micro/macronutrients from exceedingly saline environments and thrive under conditions in which salinity–sensitive crops are either unproductive or inefficient, are prime candidates for utilization in these circumstances. In addition, the bacterial microbiome associated with the roots of halophytic plants is a useful resource for the isolation of salt–tolerant bacteria with multiple plant growth–promoting characteristics, such as the production of different phytohormones, dissolution of insoluble inorganic phosphates, siderophore production, molecular nitrogen fixation, the activity of 1–aminocyclopropane–1–carboxylic acid (ACC) deaminase enzyme, and pathogen suppression, which enhance salinity tolerance of these plants as well as glycophytes and thereby stimulate the growth of plants under salinity–induced stress. The most dominant among reported halotolerant bacterial genera in most of the halophytic plants are Halomonas, Bacillus, Streptomyces, Oceanobacillus, and Pseudomonas. Here, it is shown that a wide range of halotolerant bacteria with a variety of plant growth-promoting characteristics may provide an important resource for augmenting crop tolerance to salinity and thereby boosting saline soil–based agriculture.

耐盐植物促生长菌：缓解植物盐分胁迫的前景

摘要 作为主要的非生物胁迫之一，土壤盐分对受影响地区的农业生产力、微生物群落和农业经济产生负面影响，并且是世界范围内一个在过去几十年中扩大的重大农业问题。糖生植物（对盐分敏感的植物）的使用是这种农业方法的主要限制。然而，盐生植物擅长从极度盐碱化的环境中获取必需的微量/宏量营养素，并在盐分敏感作物不生产或效率低下的条件下茁壮成长，是在这些情况下利用的主要候选者。此外，与盐生植物根部相关的细菌微生物群是分离具有多种植物生长促进特性的耐盐细菌的有用资源，例如不同植物激素的产生、不溶性无机磷酸盐的溶解、铁载体的产生、分子固氮、1-氨基环丙烷-1-羧酸（ACC）脱氨酶的活性和病原体抑制，可增强这些植物和糖生植物的耐盐性，从而刺激植物在盐胁迫下的生长。在大多数盐生植物中报道的耐盐细菌属中最主要的是盐单胞菌属、芽孢杆菌属、链霉菌属、海洋杆菌属和假单胞菌属。这里，
