Salinity is one of the most important abiotic stress factors affecting wheat production. Salt in soil a major environmental stressor that can affect bacterial community rhizosphere wheat. The bacteria plant's promote growth and tolerance, which vary by variety location. Nevertheless, harbors some diverse microbial communities, while selectively recruits according to needs plants complex harmonic regulation. composition diversity under normal saline conditions were assessed comparing with using 16S rRNA gene amplicon sequencing, highlighting number operational taxonomic units (OTUs). Taxonomic analyzes showed was predominantly characteristically composed phyla Proteobacteria, Actinobacteria, Bacteroidetes, Firmicutes, Verrucomicrobia, Fibrobacteres, representing usual profile for Idiomarinaceae, Rheinheimera, Halomonas, Pseudomonas (a strain Proteobacteria), together Gracilibacillus Firmicutes Bacilli), recognized as signatures microbiome conditions. This observed even unchanged type genotype. These patterns occurred despite same genotype, salinity being only variable. collective action these not improves nutrient availability but also induces systemic resistance plants. synergistic effect plant salt supports development salt-tolerant varieties. could improve our understanding plant-microbe interactions support microbiome-based solutions stress.
