Tea seedlings growth promotion by widely distributed and stress-tolerant PGPR from the acidic soils of the Kangra valley.

ABSTRACT: This is the first report of widespread and stress-tolerant PGPR from the tea rhizosphere of the Kangra valley. A total of 493 rhizobacteria were isolated from the major tea-growing regions of the Kangra valley. Molecular fingerprinting of 160 distinct morphotypes using ARDRA and ERIC techniques revealed intergenic and intragenic variability, resulting in the identification of 52 rRNA and 56 ERIC types belonging to 21 distantly related genera, identified by 16S rRNA gene sequencing. Bacillus constituted more than half of the genotypes, followed by Pseudomonas, Burkholderia, Lysinibacillus, Citrobacter, Enterobacter, and Paenibacillus. Bacillus altitudinis, B. cereus, B. megaterium, B. subtilis subsp. inaquosorum, B. methylotropicus, Pseudomonas frederiksbergensis, P. mohnii, and P. moreiii
