Abstract EN
The biodiversity of wheat associated bacteria was deciphered from the peninsular zone of India.
A total of 264 isolated bacteria were analyzed through amplified ribosomal DNA restriction analysis (ARDRA, using three restriction enzymes Alu I, Msp I and Hae III, which led to the clustering of these isolates into 12–16 groups for the different sites at >75% similarity index, adding up to 70 groups).
16S rRNA gene based phylogenetic analysis, revealed that all the bacteria belonged to three phyla Proteobacteria, Firmicutes, and Actinobacteria of 32 distinct species of 15 genera namely: Achromobacter, Alcaligenes, Arthrobacter, Bacillus, Delftia, Enterobacter, Exiguobacterium, Klebsiella, Methylobacterium, Micrococcus, Paenibacillus, Pseudomonas, Rhodobacter, Salmonella and Staphylococcus.
Representative strains from each cluster were screened in vitro for plant growth promoting traits.
Among plant growth promoting activities, siderophore producers were highest (15%), when compared to indole acetic acid producers (13%), Zn-solubilizers (11%), P-solubilizers (11%), ammonia (10%), hydrogen cyanide producers (9%), biocontrol (8%), N2-fixers (7%), 1-aminocyclopropane-1-carboxylate deaminase (6%), GA producers (6%) and K-solubilizers (5%).
Among 32 representative strains, Alcaligenes faecalis, Arthrobacter sp., Bacillus siamensis, Bacillus subtilis, Delftia acidovorans, Methylobacterium mesophilicum, Methylobacterium sp., Pseudomonas poae, Pseudomonas putida, and Pseudomonas stutzeri exhibited more than six different plant growth promoting activities at high temperature.
Thermotolerant bacterial isolates may have application as inoculants for plant growth promotion and biocontrol agents for crops growing at high temperature conditions.
