Endophytic Bacteria from the Desiccation-Tolerant Plant and Their Potential as Plant Growth-Promoting Microorganisms.

Bacteria associated with plants, whether rhizospheric, epiphytic, or endophytic, play a crucial role in plant productivity and health by promoting growth through complex mechanisms known as plant growth promoters. This study aimed to isolate, characterize, identify, and evaluate the potential of endophytic bacteria from the resurrection plant in enhancing plant growth, using ecotype Col. 0 as a model system.

In Vitro Evaluation of the Biosurfactant Produced by Serratia ureilytica UTS with Antifungal and Nematicidal Activity Against Nacobbus aberrans.

In the present study, the nematicidal and fungicidal activity of the biosurfactant (BS) produced by the strain Serratia ureilytica UTS was evaluated. The highest mortality of J2 juveniles of the nematode Nacobbus aberrans was 92.3% at a concentration of 30 mg/mL.

In Vivo Production, Development and Storage of (Nematoda: Rhabditida) in (Lepidoptera: Pyralidae).

Entomopathogenic nematodes have been used in biological control for some time and are an alternative for the control of insect pests, but during their implementation, situations have arisen that can be improved. These vary with each species and include their production and storage. , an entomopathogenic nematode (EPN), was monitored for its performance when produced in vivo, as well as its development using larvae, using the MC5-2014 strain isolated from soil samples in the municipality of Tepalcingo, Morelos, México.

Plasmids of the incompatibility group FIB occur in Klebsiella variicola from diverse ecological niches.

Plasmids play a fundamental role in the evolution of bacteria by allowing them to adapt to different environments and acquire, through horizontal transfer, genes that confer resistance to different classes of antibiotics. Using the available in vitro and in silico plasmid typing systems, we analyzed a set of isolates and public genomes of K. variicola to study its plasmid diversity.

A Versatile Peroxidase from the Fungus Confers Abiotic Stress Tolerance in Transgenic Tobacco Plants.

White-rot fungi are efficient lignin degraders due to the secretion of lignin peroxidase, manganese peroxidase, laccase, and versatile peroxidase (VP) on decayed wood. The VP is a high-redox-potential enzyme and could be used to detoxify reactive oxygen species (ROS), which accumulate in plants during biotic and abiotic stresses. We cloned the gene and expressed it via the transformation procedure in transgenic tobacco plants to assay their tolerance to different abiotic stress conditions.
