Pigeonpea (Cajanus cajan) is an important legume crop in semi-arid regions with multiple uses. The microbial diversity within its root nodules Indian soils remains poorly explored. We investigated the bacterial of pigeonpea across different genotypes and soil types to identify factors driving their assembly. Using a metagenomic approach high-throughput sequencing 16S rRNA gene, we analyzed nodule microbiomes three (Asha, Durga, Mannem Konda Kandi) grown (Alfisol, Vertisol, Inceptisol) wild (C. scarabaeoides) native soil. Our results indicated that harbor diverse rhizobial non-rhizobial endophytes host genotype, position, type, other edaphic influence significant variation community structure. core microbiome was dominated by Proteobacteria Bacteroidetes. Bradyrhizobium Ensifer were predominant among taxa, genera such as Pseudomonas, Chitinophaga, Limnobacter also abundant. Edaphic factors, particularly pH, nutrient availability, had stronger on composition than genotype. Although bulk exhibited higher diversity, less but more specialized, indicating host-mediated selection. A comparison cultivated revealed distinct differences, Bradyrhizobium, while community. These findings demonstrate properties play critical role genetics shaping microbiome, emphasizing importance environmental conditions symbiotic interactions. differences between suggest domestication has altered recruitment strategies. This study provides foundational insights into assembly nodules, implications for improving productivity through targeted management. Future research should explore functional roles these communities optimize use sustainable agriculture.

The increasing intensity of environmental stresses presents significant challenges to modern agriculture. assorted group all stress-related genes and mechanisms carried out by various soil-inhabiting microorganisms could readily contribute resistance in crop plants represented as soil factors (SRFs). It is essential have a profound knowledge the SRFs their interaction with current basic develop appropriate strategies that effectively improve plant growth. Modern microbiological research dedicated understanding relationship between organization gene function involved processes. A fraction scientific community primarily engaged developing culture-independent techniques substantial (99%) portion still not cultivable laboratory conditions. However, exploitation are commencement. metagenomic method has proven be strong methodological tool for microbiome SRF analysis. obtaining detail any particular can completely characterize intricacy metagenomes interpret meaningful conclusions about native microbial communities challenging. This review provides an overview methods employed gain insights into specific microbiomes confer abiotic biotic on crops.
