Plant secondary metabolites (PSMs) play many roles including defense against pathogens, pests, and herbivores; response to environmental stresses, mediating organismal interactions. Similarly, plant microbiomes participate in of the above-mentioned processes directly or indirectly by regulating metabolism. Studies have shown that plants can influence their microbiome secreting various and, turn, may also impact metabolome host plant. However, not much is known about communications between interacting partners phenotypic changes. In this article, we review patterns potential underlying mechanisms interactions PSMs microbiomes. We describe recent developments analytical approaches methods field. The applications these new increased our understanding relationships Though current studies primarily focused on model organisms, results obtained so far should help future agriculturally important facilitate development manipulate PSMs–microbiome with predictive outcomes for sustainable crop productions.

Insights into the Interactions among Roots, Rhizosphere, and Rhizobacteria for Improving Plant Growth and Tolerance to Abiotic Stresses: A Review

Cells, Journal Year: 2021, Volume and Issue: 10(6), P. 1551 - 1551

Published: June 19, 2021

Abiotic stresses, such as drought, salinity, heavy metals, variations in temperature, and ultraviolet (UV) radiation, are antagonistic to plant growth development, resulting an overall decrease yield. These stresses have direct effects on the rhizosphere, thus severely affect root growth, thereby affecting health, productivity. However, growth-promoting rhizobacteria that colonize rhizosphere/endorhizosphere protect roots from adverse of abiotic stress facilitate by various indirect mechanisms. In plants constantly interacting with thousands these microorganisms, yet it is not very clear when how complex root, interactions occur under stresses. Therefore, present review attempts focus root-rhizosphere rhizobacterial respond interactions, role Further, focuses underlying mechanisms employed for improving architecture tolerance

The Role of Plant Growth-Promoting Rhizobacteria (PGPR) in Mitigating Plant’s Environmental Stresses

Applied Sciences, Journal Year: 2022, Volume and Issue: 12(3), P. 1231 - 1231

Published: Jan. 25, 2022

Phytoremediation is a cost-effective and sustainable technology used to clean up pollutants from soils waters through the use of plant species. Indeed, plants are naturally capable absorbing metals degrading organic molecules. However, in several cases, presence contaminants causes suffering limited growth. In such situations, thanks production specific root exudates, can engage most suitable bacteria able support their growth according particular environmental stress. These growth-promoting rhizobacteria (PGPR) may facilitate development with beneficial effects, even more evident when grown critical conditions, as toxic contaminants. For instance, PGPR alleviate metal phytotoxicity by altering bioavailability soil increasing translocation within plant. Since many also hydrocarbon oxidizers, they enhance biodegradation activity. Besides, agriculture be an excellent counter devastating effects abiotic stress, excessive salinity drought, replacing expensive inorganic fertilizers that hurt environment. A better in-depth understanding function interactions associated microorganisms directly matrix interest, especially persistent contamination, could provide new opportunities for phytoremediation.
