What is the Rhizosphere effect? The rhizosphere effect is the influence of plant roots on the development of soil microorganisms as a result of the physical and chemical alteration of soil and the release of root secretions and exudates within the rhizosphere. Rhizosphere effect is established in the root region due to secretion of root exudates as compared to non-rhizospheric soil. Gene expression is altered through genetic engineering in plants; therefore, the root exudates and secretions are also changed which result in aggressive root colonisation by desirable microorganisms. In the presence of plants, a priming effect occurs in the direct vicinity of the living roots, and it is called rhizosphere priming effect (RPE). Plant‐mediated and environmental factors, such as, plant species, development stage, soil organic matter content, photosynthesis intensity, and N fertilization which affect RPE are reviewed and discussed in this paper. the rhizosphere effect (Morgan et al., 2001).

Broadly, there are three distinct components recognized in the rhizosphere; the rhizosphere per se (soil), the rhizoplane, and the root itself. The rhizosphere is thus the zone of soil influencedby roots through the release of substrates that affect microbial activity. 2020-05-26 2018-01-15 2016-11-28 2017-11-07 2020-02-12 Rhizosphere microbiome (disrupted vs. intact native microbiome) had no effect on plant GLS concentrations. However, aphid number and flea beetle damage were respectively about three‐ and seven‐fold higher among plants grown in the disrupted versus intact native microbiome treatment.

Soil type and its moisture: In general, microbial activity and population is high in the rhizosphere region of the plants grown in sandy soils and least in the high humus soils, and rhizosphere organisms are more when the soil moisture is low.

Plant roots have strong effects on the physical environment in the rhizosphere. Shifts in the physical environment, which are influenced by root manipulation, have significant impacts on the availability and form of substrates used for microbial metabolism.

Rhizosphere effect is mainly governed by plant carbonic organic compounds released from plants and siderophores produced by microorganisms. The root surface area determines the extension of the rhizosphere effect.

The rhizosphere effect is expressed quantitatively as the ratio of the number or activity of microorganisms or level of root exudates in rhizosphere soil (R) to that in the edaphosphere soil (E), i.e., the R ⧸ E ratio. Effects of rhizosphere is almost negligible for algae and protozoa. It is because algae are photosynthetic and do not depends upon organic matter present in root exudates. On the other hand most bacteria cannot utilize relatively resistant to organic matter of soil and depends on easily available decomposable matter of root exudates. The rhizosphere effect is the phenomenon in which plant roots provide abundant nutrients and energy for microorganisms, so that the number and activity of microorganisms in the rhizosphere is significantly higher than elsewhere in the soil (Wang et al., 2016; Sun et al., 2020). The rhizosphere effect was observed for trace metals in addition to Pb, with the solubility of Al, Fe, Cu and Ni all increasing in the rhizosphere soil. In contrast, the solubility of alkali and alkaline earth metals (K, Ca, Mg, Sr, Ba) all decreased in the rhizosphere soil.
