促进植物生长的微生物（根际细菌和菌根真菌）为提高作物产量提供了一种可持续的替代方案，沿着改善了不同环境中的土壤健康。本研究的目的是阐明与接种AM真菌和PGPR沿着与有机肥和由此产生的改善植物生长在自然发生的盐胁迫下的固有根际微生物群落发生的变化。结果表明，在温室和田间试验中，在盐胁迫土壤条件下，施用生物接种剂（Dietzia natronolimnaea STR 1和Glomus intraradices（Gi））以及沿着有机肥料（蚯蚓粪）改善了罗勒CIM-Saumya植物的生长。通过末端限制性片段长度多态性（TRFLP）分析的RoundSpherical微生物（细菌和真菌）群落结构表明了微生物接种对土著微生物群落结构的积极影响。一个显着的影响，联合接种的细菌群落中观察到的相比，任何一个生物接种剂的单一应用程序，然而，这种效果并没有在真菌群落结构迭代。(C)© 2016 Elsevier B.

Plant growth promoting microorganisms (rhizospheric bacteria and mycorrhizal fungi) provide a sustainable alternative to enhanced crop production along with improved soil health in varying environments. The present study was aimed to elucidate the alteration occurring in innate rhizospheric microbial communities associated with inoculation of AM fungi and PGPR along with organic manure and the resulting improved plant growth under naturally occurring salt stress. The results demonstrate improved growth of Ocimum basilicum CIM-Saumya plants applied with bio-inoculants (Dietzia natronolimnaea STR1 and Glomus intraradices (Gi)) along with organic manure (vermicompost) under salt stressed soil conditions in both glasshouse and field trials. Rhizospheric microbial (bacteria and fungi) community structure as analyzed through terminal restriction fragment length polymorphism (TRFLP) demonstrated a positive effect of microbial inoculation on the indigenous microbial community structure. A notable impact of combined inoculations on the bacterial community was observed in comparison to single applications of either of the bio-inoculants; however, this effect was not iterated in fungal community structure.
