Plant growth-promoting Bacillus amyloliquefaciens orchestrate homeostasis under nutrient deficiency exacerbated drought and salinity stress in Oryza sativa L. seedlings.

Nutrient deficiency intensifies drought and salinity stress on rice growth. Bacillus amyloliquefaciens inoculation provides resilience through modulation in metabolic and gene regulation to enhance growth, nutrient uptake, and stress tolerance. Soil nutrient deficiencies amplify the detrimental effects of abiotic stresses, such as drought and salinity, creating substantial challenges for overall plant health and crop productivity.

Bacillus amyloliquefaciens modulate autophagy pathways to control Rhizoctonia solani infection in rice.

The necrotrophic fungus Rhizoctonia solani significantly threatens rice harvests and agricultural productivity by causing sheath blight disease. This study investigates the potential of the plant growth-promoting rhizobacteria Bacillus amyloliquefaciens (SN13) as a biocontrol agent in the sensitive rice variety Swarna against R. solani infection.

Pseudomonas putida triggers phosphorus bioavailability and P-transporters under different phosphate regimes to enhance maize growth.

The decline of available phosphorus in soil due to anthropogenic activities necessitates utilizing soil microorganisms that influence soil phosphorus levels. However, the specific mechanisms governing their interaction in Zea mays under diverse phosphate regimes remain largely unknown. The present study investigated the dynamics of phosphorus solubilization and the impact of organic acid supplementation in combination with the beneficial rhizobacterium Pseudomonas putida (RA) on maize growth under phosphorus-limiting and unavailable conditions.

Symphony of survival: Insights into cross-talk mechanisms in plants, bacteria, and fungi for strengthening plant immune responses.

Plants coexist with a diverse array of microorganisms, predominantly bacteria and fungi, in both natural and agricultural environments. While some microorganisms positively influence plant development and yield, others can cause harm to the host, leading to significant adverse impacts on the environment and the economy. Plant growth-promoting microorganisms (PGPM), including plant growth-promoting bacteria, arbuscular mycorrhizal fungus (AMF), and rhizobia, have been found to increase plant biomass production by synthesizing hormones, fixing nitrogen, and solubilizing phosphate and potassium.

Paenibacillus lentimorbus alleviates nutrient deficiency-induced stress in Zea mays by modulating root system architecture, auxin signaling, and metabolic pathways.

Paenibacillus lentimorbus reprograms auxin signaling and metabolic pathways for modulating root system architecture to mitigate nutrient deficiency in maize crops. The arable land across the world is having deficiency and disproportionate nutrients, limiting crop productivity. In this study, the potential of plant growth-promoting rhizobacteria (PGPR) viz.

The hidden harmony: Exploring ROS-phytohormone nexus for shaping plant root architecture in response to environmental cues.

Root system architecture, encompassing lateral roots and root hairs, plays a vital in overall plant growth and stress tolerance. Reactive oxygen species (ROS) and plant hormones intricately regulate root growth and development, serving as signaling molecules that govern processes such as cell proliferation and differentiation. Manipulating the interplay between ROS and hormones has the potential to enhance nutrient absorption, stress tolerance, and agricultural productivity.
