Induced disease resistance elicited by acibenzolar-S-methyl and plant growth-promoting rhizobacteria in tobacco (Nicotiana tabacum L.)
Active disease resistance in plants is induced during the pathogen infection process that triggers multiple defense-related genes to establish broad-spectrum resistance. Several biotic and abiotic agents can mimic natural induced resistance (IR), categorized as systemic acquired (SAR) or induced …

Exploring the Genomic, Plant Growth Promoting, and Biocontrol Potential of a novum species 'Candidatus Pseudomonas auctus' JDE115 with its description
… soybean (Glycine max) root nodules in Virginia. Growth occurred at 0–5.0% NaCl (optimum 1%), pH 6.0–10.0 (optimum 7.0), and 10–40°C (optimum 28°C). Phylogenetic analysis based on the 16S rRNA gene and whole-genome sequencing placed JDE115 within the genus Pseudomonas, with the highest similarity …
