Amelioration of Salinity Stress and Enhancing Growth in Wheat Seedling using Halotolerant Arthrobacter sp. NIMD28
55 / 46
Keywords:
Arthrobacter sp., Bacterial Metabolites, Halotolerant rhizobacteria, Salinity stress, induced systemic toleranceAbstract
Growth promotion and salinity stress-attenuation ability of the metabolites secreted by plant growth promoting, halotolerant Arthrobacter sp. NIMD28 (LC189176) was evaluated on germination, establishment, and development of wheat. The isolate produced diverse types of biomolecules in varying concentrations. Metabolites produced by the isolate also showed presence of phenolic compounds with significant non-enzymatic antioxidant activity. The gnotobiotic seed germination experiment revealed interesting results, where despite of the halotolerant nature, the isolate seems lagged in the plant growth promotion (PGP) over the in vitro induced metabolites of its own in terms of the phenotypic, biochemical and enzymatic characters. The Pearson’s correlation coefficient and hierarchical clustering analyses also endorsed the performance of metabolites under saline conditions. The results strongly endorse needful initiatives towards keen optimization of the dose-response of the metabolites at larger scale, to develop next generation, sustainable bio-inoculants for abiotically stressed habitats.
