Effect of Arbuscular mycorrhizal fungi and plant growth-promoting rhizobacteria on glomalin production
… However, other soil microorganisms such as plant growth-promoting rhizobacteria (PGPR) that interact with AMF could indirectly influence glomalin production. The objectives of this study were to determine the effects of AMF and PGPR interactions on glomalin production and identify possible …

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 …

Estudio de genómica comparada de genes bacterianos relacionados con la proliferación en la rizosfera
… species for its mutualistic relationship with plants at the rhizosphere level, Pseudomonas putida. It is considered a rhizobacteria that promotes plant growth, also knows as a PGPR (Plant-Growth Promoting Rhizobacteria). The different stages of colonization have been defined, being the …

Analyse comparative portant sur l'effet de la rhizobactérie pseudomonas fluorescens LBUM677 sur l'accumulation lipidique chez différentes plantes oléagineuses ainsi que sur leurs microbiomes
… rhizobactéries promotrices de la croissance des plantes (PGPR) pour 'Plant Growth Promoting Rhizobacteria'). Le premier objectif de cette étude consiste à caractériser la dynamique de population de la souche LBUM677 de Pseudomonas fluorescens dans les rhizosphères de trois espèces de plantes …

Pseudomonas spp. Isolated from the Soybean Nodule Interior Promote Soybean Growth upon Field Amendment
… Pseudomonas associates with soybean nodules as a plant-growth promoting rhizobacteria (PGPR). This study observes the soybean growth promoting potential of Pseudomonas spp. in a field setting. Additionally, this study observed differences in soybean growth promotion based on amending the plant …

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 …

Burkholderia phytofirmans strain PsJN effects on drought resistance, physiological responses and growth of switchgrass
… traditional management practices though applying plant growth promoting rhizobacteria (PGPR), of which our understanding is still rather limited. To elucidate physiological mechanisms behind PGPR's beneficial effects, we inoculated switchgrass seedlings with Burkholderia phytofirmans strain PsJN. …

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 …

The development of a transparent soil and its application in imaging root trajectories and root bacteria interactions
… implications. These processes include root growth and microbial interactions with roots and soil particles and they influence the efficiency of crop production and, in turn, global food security. The observation and imaging of these below-ground processes is difficult due to the opacity of …

Is AtGSTF2 involved in lumichrome perception and transport?
ENGLISH ABSTRACT: A number of exudates from plant growth-promoting rhizobacteria (PGPR) have been increasingly studied and used as an alternative way of promoting plant health and growth. One such exudate is lumichrome, a signal molecule which has been shown to elicit a growth response across …

Investigating behaviors of zoonotic and human pathogens on plants
… within the phyllosphere and rhizosphere of these plants is an extremely complex issue. In addition, the CDC estimates that unspecified agents are responsible for 38.4 million out of the 48 million (80 %) cases of foodborne illnesses. It is hypothesized that environmental E. coli not typically …

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 …

Pseudomonas spp. Isolated from Soybean Nodules Promote Soybean Growth and Nitrogen Fixation
… soybean nodules convert atmospheric nitrogen to plant-available forms in exchange for carbon from the plant, but other non-nitrogen-fixing bacteria also reside in nodules, and their role in the nodule is not well understood. This study was conducted to determine the effect of three …

The exploration of potato-associated bacteria in the Central Andean Highlands and their application in integrated crop management systems
… the influence of microbial isolates on plant defence responses was determined. Volatile organic compounds of bacterial isolates were identified using GC/MS. RT-qPCR analysis revealed the significant expression of Ethylene Response Factor 3 (ERF3) and the results of this study suggest …
