Optimizing plant growth, nutrient uptake, and yield of onion through the application of phosphorus solubilizing bacteria and endophytic fungi.

Introduction: The application of mineral fertilizers deteriorates soil properties and affects crop yield and nutritional properties. However, plant growth-promoting microorganisms (PGPM- , phosphorus solubilizing bacteria (PSB), and vesicular arbuscular mycorrhizae (VAM)) have great potential to reduce fertilizers and improve soil fertility, crop yield, and nutrient uptake and mitigate the environmental effect of mineral fertilizers.

Material And Methods: Hence, a field experiment was conducted involving nine treatments to evaluate the effects of PGPM along with 50% or 100% of the recommended dose of fertilizers on plant growth, soil fertility, nutrient uptake, and onion productivity.

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.

Exploring Potent Fungal Isolates from Sanitary Landfill Soil for In Vitro Degradation of Dibutyl Phthalate.

Di-n-butyl phthalate (DBP) is one of the most extensively used plasticizers for providing elasticity to plastics. Being potentially harmful to humans, investigating eco-benign options for its rapid degradation is imperative. Microbe-mediated DBP mineralization is well-recorded, but studies on the pollutant's fungal catabolism remain scarce.

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.

Co-cultivation Approach to Decipher the Influence of Nitrogen-Fixing Cyanobacterium on Growth and N Uptake in Rice Crop.

The present study was performed to evaluate the efficacy of selected potential nitrogen-fixing cyanobacterial strain (Anabaena sp.), isolated from rhizospheric soil of rice plants on growth, pigments, N uptake, root architecture, and image-based phenotypic traits of rice crop using co-cultivation approach under controlled sand culture conditions. We studied the beneficial interaction of cyanobacterium to rice using sensor image-based Phenomics approach as well as conventional methods.

Use of Phenomics for Differentiation of Mungbean ( L. Wilczek) Genotypes Varying in Growth Rates Per Unit of Water.

In the human diet, particularly for most of the vegetarian population, mungbean ( L. Wilczek) is an inexpensive and environmentally friendly source of protein. Being a short-duration crop, mungbean fits well into different cropping systems dominated by staple food crops such as rice and wheat.

Comparative conventional and phenomics approaches to assess symbiotic effectiveness of Bradyrhizobia strains in soybean (Glycine max L. Merrill) to drought.

Symbiotic effectiveness of rhizobitoxine (Rtx)-producing strains of Bradyrhizobium spp. in soybean (cultivar NRC-37/Ahilya-4) under limited soil moisture conditions was evaluated using phenomics tools such as infrared(IR) thermal and visible imaging. Red, green and blue (RGB) colour pixels were standardized to analyse a total of 1017 IR thermal and 692 visible images.

Assimilates mobilization, stable canopy temperature and expression of expansin stabilizes grain weight in wheat cultivar LOK-1 under different soil moisture conditions.

Background: Grain yield of wheat is primarily determined by both grain number and grain weight, which often influence each other in response to environmental stimuli. Some of the genotypes are capable of maintaining high single grain weight (SGW) across the environments. Understanding mechanisms and factors associated with the superiority of such genotypes over others is necessary to enhance productivity of wheat.

Functional and phylogenetic diversity of cultivable rhizobacterial endophytes of sorghum [Sorghum bicolor (L.) Moench].

A diverse group of bacteria colonize the exo- and endo-rhizospheres of sorghum and play a critical role in its tolerance to drought and other abiotic stresses. Two hundred and eighty endophytic bacteria were isolated from the surface-sterilized roots of four sorghum cultivars that were grown on three soil types at three different phenological stages of growth. The isolates were subjected to in vitro screening for their plant growth promoting traits.

Isolation and characterization of ACC deaminase gene from two plant growth-promoting rhizobacteria.

Lowering of plant ethylene by deamination of its immediate precursor 1-aminocyclopropane-1-carboxylate (ACC) is a key trait found in many rhizobacteria. We isolated and screened bacteria from the rhizosphere of wheat for their ACC-degrading ability. The ACC deaminase gene (acdS) isolated from two bacterial isolates through PCR amplification was cloned and sequenced.
