Effects of co-inoculation of Delftia acidovorans RAY209 on the growth of Bradyrhizobium diazoefficiens USDA110 inoculated Glycine max
… pressure will be driven by continued population growth, an unprecedented and growing demand for high quality protein, environmental degradation caused by chemical fertilizers, and also be the need for agriculture to be more sustainable. Inoculating crops with plant growth-promoting rhizobacteria …

DISCLOSING THE ROLE OF ROOT EXUDATES IN MODULATING THE INTERACTION BETWEEN PLANT AND XENOBIOTIC DEGRADING BACTERIA
Positive interactions between plants and root-associated bacteria are fundamental to maintain the homeostasis of the holobiont, especially upon environmental stresses. This crosstalk is mediated by root exudates (REs), including plant secondary metabolites, that are released by the plant as a …

Plant genotype, immunity and soil composition control the rhizosphere microbiome
Three model plant and three crop plant species were grown for three generations in sand and compost. Pots were inoculated with 10 % soil initially, and with 10% of growth medium from the previous generation in generations 2 and 3, keeping replicates separate for all three generations. The …

The Plant Growth-Promoting Potential of Root-Associated Bacteria from Plants Growing in Stressed Environments
… studies have demonstrated the potential of plant growth-promoting bacteria, including their use as inoculants, in the contexts of both agriculture and enhanced phytoremediation. Despite their promise, there is still a need to characterize and identify plant growth-promoting bacteria amidst …

Metatranscriptomic analysis of community structure and metabolism of the rhizosphere microbiome.
Plant-microbe interactions in the rhizosphere, the region of soil influenced by plant roots, are integral to biogeochemical cycling, and maintenance of plant health and productivity. Interactions between model plants and microbes are well understood, but relatively little is about the plant …

Enhancement of cold tolerance and growth of tomato plants using endophytic bacteria isolated from cold-adapted plants
… can occur. Microbial communities associated with plants in cold environments can enhance plant growth at low temperatures and boost their tolerance to cold stress. Thus, the use of cold-tolerant endophytic bacteria could be a promising approach to protect crop plants from cold stress. This work …

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 …

Utilizing Beneficial Bacterial Endophytes to Promote Switchgrass Growth in Low- input Agricultural Production Systems
… Bacterial endophytes, which reside inside plant tissues, are proven to increase yield and stress resistance in a number of plants. The primary objective of this dissertation was to explore the use of endophytes to improve biomass yields of switchgrass on lands not suitable for food crops …

Characterization of tomato root-endophytic fungi and analysis of their effects on plant development, on fruit yield and quality and on interaction with the pathogen Verticillium dahliae
… neutral or mutualistic associations with plants. These fungi known as non-clavicipitaceous endophytes have a broad host range of monocot and eudicot plants and are highly diverse. Some of them promote plant growth and confer increased abiotic-stress tolerance and disease resistance. …

Benzoic acid regulates the physio-biochemical responses of chia (Salvia hispanica L.) seedlings under salinity stress
ENGLISH Plant immobility renders plants constantly susceptible to various abiotic and biotic stresses. These stresses generate reactive oxygen species (ROS), which cause cellular damage through osmotic or oxidative stress, ultimately constraining agricultural productivity worldwide. To mitigate the …
