Pseudomonas spp. Isolated from the Soybean Nodule Interior Promote Soybean Growth upon Field Amendment
… 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 with isolated strains or a …

Plant genotype, immunity and soil composition control the rhizosphere microbiome
… order to enrich it with plant growth promoting rhizobacteria (PGPR) species. However, in some plant species rhizospheres, invasions of opportunists and pathogens take place, mimicking events in plant monocultures. Other experiments using this multi-replicate system allowed for statistical …

Elucidating the Molecular Pathways Involved in the Fitness and Water Stress Response of Pseudomonas synxantha 2-79 in the Plant Rhizosphere
… agent that represents beneficial indigenous rhizobacteria that are broadly distributed in the Pacific Northwest, USA and flourish in the rhizosphere of commercially grown wheat under surprisingly arid conditions. The molecular adaptation of 2-79-like bacteria to plants growing in dry soils is …

Biochar: for better or for worse?
… biochar was tested as microbial carrier. Rhizobacteria survival was established to be higher in biochar produced from redwood than in peat (a common microbial carrier) at high incubation temperatures (25°C and 35°C). In conclusion, biochar addition to soil presents limited direct …

Burkholderia phytofirmans strain PsJN effects on drought resistance, physiological responses and growth of switchgrass
… 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. Two experiments were …

Plant community restoration on mima mounds at Turnbull National Wildlife Refuge, WA
… test effectiveness of an experimental strain of rhizobacteria, Pseudomonas fluorescens D7, for invasive annual grass reduction. I surveyed plant species composition and cover in 235 1 m² vegetation plots in June-July 2009, measured environmental variables for 203 of the plots, applied treatments …

Effects of co-inoculation of Delftia acidovorans RAY209 on the growth of Bradyrhizobium diazoefficiens USDA110 inoculated Glycine max
… Inoculating crops with plant growth-promoting rhizobacteria (PGPR) has emerged to fill in the gap between the growing demand for food and sustainable agriculture as it promotes plant growth, reduces crop susceptibility to abiotic and biotic stress, and ultimately facilitates producing foods in …

The development of a transparent soil and its application in imaging root trajectories and root bacteria interactions
… fluorescens, a plant growth promoting rhizobacteria, associates closely with plant roots and can act as a biocontrol agent by conveying pathogen resistance to the plant. For this reason, the interaction between lettuce roots and GFP labelled P. fluorescens was studied with the aim of …

Is AtGSTF2 involved in lumichrome perception and transport?
… 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 multiple species. …

Studies of genera cytophaga-flavobacterium in context of the soil carbon cycle
There is a great need to understand the global carbon cycle; with specific interest in the cycling of soil carbon. This need is two-fold and interconnected. The global climate change is in-part due to the loss of soil organic carbon and the reduced ability of soils to sequester carbon. Also, to …
