Comparative metagenomic analysis of rice soil samples revealed the diverse microbial population and biocontrol organisms against plant pathogenic fungus Magnaporthe oryzae.

ABSTRACT: Intensive cropping degrades soil quality and disrupts the soil microbiome. To understand the effect of rice monocropping on soil-microbiome, we used a comparative 16S rRNA metagenome sequencing method to analyze the diversity of soil microflora at the genomic level. Soil samples were obtained from five locations viz., Chamarajnagara, Davangere, Gangavathi, Mandya, and Hassan of Karnataka, India. Chemical analysis of soil samples from these locations revealed significant variations in pH (6.00-8.38), electrical conductivity (0.17-0.69 dS m^-1), organic carbon (0.51-1.29%), available nitrogen (279-551 kg ha^-1), phosphorous (57-715 kg ha^-1) and available potassium (121-564 kg ha^-1). The 16S metagenome analysis revealed that the microbial diversity in
