The rhizosphere effect on most commonly found microorganisms viz. bacteria, actinomycetes, fungi, algae and protozoa is being discussed herewith in the following paragraphs. A. Bacteria: The greater rhizosphere effect is observed with bacteria (R: S values ranging from 10-20 or more) than with actinomycetes and fungi.

However, it is still unclear to what extent successful plant growth-promoting effects are driven by the origin of the microbial inocula and which taxa are responsible for the plant-beneficial effects.
2020-05-26 · Aims The rhizosphere priming effect (RPE) is the change in decomposition of soil organic matter caused by root activity, and it can be affected by plant species, nutrient availability, and by many other factors. Although plant and soil nitrogen (N) are likely to greatly influence RPE and vice-versa, not much is known about these relationships. There is a need for more research, particularly in
In this episode Octavia takes a look at the Rhizosphere - a term given to the thin region of soil around a root hair where interactions occur between the roo
One of the contributing factors to this uncertainty is the lack of understanding about the role of rhizosphere priming effect (RPE) in shaping the temperature sensitivity.

Microorganisms colonizing the plant rhizosphere provide a number of beneficial functions for their host. Although an increasing number of investigations clarified the great functional capabilities of rhizosphere microbial communities, the understanding of the precise mechanisms underlying the impact of rhizosphere microbiome assemblies is still limited. Also, not much is known about the Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties.

Mean effect size (log response ratio) of litter (solid circle) and rhizosphere (open circle) effects of plant invasion on soil biota and their functions. Positive effect sizes means that the values under invasive plants are higher than those under native plants, and negative effects sizes means the values are lower under invasive plants than native plants.
RHIZOSPHERE EFFECT Compared to non-rooted bulk soil , the rhizospheric soil around the plant root contains much larger population of microorganism. A stimulation that can be put on a quantitative basis by the use of the R：S ratio R：S ratio = number of microorganisms in the rhizosphere soil：number of microorganisms in the non-rhizosphere soil.
