Enhancing wheat growth and nutrient content through integrated microbial and non-microbial biostimulants.

This study focused on two aspects: to develop a selected functionally competent bacterial community, and its integrated with biostimulant humic acid and seaweed extract which was validated to enhance wheat growth and nutrient content. Wheat and maize-associated bacterial isolates (92) were screened for Plant Growth-Promoting traits (PGPts-72) and Community-Forming traits (CFts-66). 46 isolates possessed both kinds of traits, of which 20 isolates were chosen based on high Bonitur scale ratings.

Community-forming traits play role in effective colonization of plant-growth-promoting bacteria and improved plant growth.

Community-forming traits (CFts) play an important role in the effective colonization of plant-growth-promoting bacterial communities that influence host plants positively by modulating their adaptive functions. In this study, by considering plant-growth-promoting traits (PGPts) and community-forming traits (CFts), three communities were constructed, , SM1 (PGPts), SM2 (CFts), and SM3 (PGPts+CFts). Each category isolates were picked up on the basis of their catabolic diversity of different carbon sources.

Seed endophytic bacterial profiling from wheat varieties of contrasting heat sensitivity.

Wheat yield can be limited by many biotic and abiotic factors. Heat stress at the grain filling stage is a factor that reduces wheat production tremendously. The potential role of endophytic microorganisms in mitigating plant stress through various biomolecules like enzymes and growth hormones and also by improving plant nutrition has led to a more in-depth exploration of the plant microbiome for such functions.

Characterization of actinobacteria from wheat seeds for plant growth promoting traits and protection against fungal pathogens.

Seeds harbor naturally occurring microbial endophytes that proliferate during seedling development; playing crucial roles in seedling growth, establishment, and protection against fungal pathogens. Resilient actinobacteria of wheat seeds have been explored in this study for their beneficial traits. Ten actinobacteria isolated from the surface-sterilized seeds of wheat variety HD3117 were identified as nine species of Streptomyces and one of Nocardiopsis.

Microbial Community and Function-Based Synthetic Bioinoculants: A Perspective for Sustainable Agriculture.

Interactions among the plant microbiome and its host are dynamic, both spatially and temporally, leading to beneficial or pathogenic relationships in the rhizosphere, phyllosphere, and endosphere. These interactions range from cellular to molecular and genomic levels, exemplified by many complementing and coevolutionary relationships. The host plants acquire many metabolic and developmental traits such as alteration in their exudation pattern, acquisition of systemic tolerance, and coordination of signaling metabolites to interact with the microbial partners including bacteria, fungi, archaea, protists, and viruses.

Prospecting catabolic diversity of microbial strains for developing microbial consortia and their synergistic effect on Lentil (Lens esculenta) growth, yield and iron biofortification.

Carbon profiling of heterotrophic microbial inoculants is worthwhile strategy for formulating consortium-based biofertilizers. Consortium-based biofertilizers are better than single strain-based biofertilizers for sustaining agricultural productivity and enhancing micronutrient concentration in grains. Currently, we investigated catabolic diversity among microbes using different carbon sources and certain enzyme activities.
