This study focuses on the isolation and characterization of a high cadmium (Cd)-resistant bacterial strain, and possible exploitation of its Cd-accumulation and Cd-induced siderophore production property to improve plant growth in cadmium-contaminated soil through root colonization. The bacterial strain could tolerate up to 8 mM of Cd and could accumulate Cd intracellularly. The strain showed Cd-induced siderophore production maximally at 1.75 mM of Cd concentration under culture condition. It stimulated the growth of mustard and pumpkin plants in Cd-added soil through its establishment in rhizosphere. Through biochemical characterization and 16S rDNA sequence analysis, the strain KUCd1, as the name given to it, was identified as a strain of Pseudomonas aeruginosa.

Fungal diseases in agricultural crops cause economic losses, with chemical control being the conventional method to manage them. However, this approach negatively impacts both the environment and human health. This study focused on endophytic fungi isolated from the roots of Ceratozamia mirandae in the Mexican locality of Juan Sabines (Villa Corzo, Chiapas).

is the main cause of soft rot in kiwifruit, significantly reducing both yield and quality. While chemical treatments are commonly used, their effectiveness is limited and they may pose environmental risks. As a result, biological control using Bacillus species has emerged as a promising alternative.

Introduction: Wheat is one of the three major cereal crops in the world and is susceptible to the effects of drought stress. Rhizosphere microorganisms can affect plant growth by altering nutrient absorption and resistance to stress. Studying the plant-microbe interaction under drought stress to reveal the impact of soil microorganisms on plant growth in dry land has important scientific significance.

Methane is a potent greenhouse gas and a target for near-term climate change mitigation. In many natural ecosystems, methane is sequestered by microbial communities, yet little is known about how constituents of methane-oxidizing communities interact with each other and their environment. This lack of mechanistic understanding is a common issue for many important microbial communities, but it is difficult to draw links between available sequencing information and the metabolites that govern community interactions.

-diazeniumdiolate siderophores are a small class of photoactive bacterial Fe(III) chelators. Driven by genome mining, we discovered a new -type diazeniumdiolate siderophore, pandorachelin, produced by the rhizospheric bacterium, DSM 11628. The biosynthetic gene cluster encoding the production of pandorachelin is conserved across several species.
