Perspectives of plant-associated microbes in heavy metal phytoremediation.
TLDR
How such processes influence heavy metal uptake through various biogeochemical processes including translocation, transformation, chelation, immobilization, solubilization, precipitation, volatilization and complexation of heavy metals ultimately facilitating phytoremediation is illustrated.About:

Embracing the unknown: disentangling the complexities of the soil microbiome.
TL;DR: Although most soil microorganisms remain undescribed, the field is now poised to identify how to manipulate and manage the soil microbiome to increase soil fertility, improve crop production and improve the understanding of how terrestrial ecosystems will respond to environmental change.

Microbial and Plant-Assisted Bioremediation of Heavy Metal Polluted Environments: A Review
TL;DR: The toxic effects of heavy metal pollution and the mechanisms used by microbes and plants for environmental remediation are discussed and the importance of modern biotechnological techniques and approaches in improving the ability of microbial enzymes to effectively degrade heavy metals at a faster rate is emphasized.
Journal ArticleDOI
Microbial interactions in the rhizosphere: beneficial influences of plant growth-promoting rhizobacteria on nutrient acquisition process. A review
TL;DR: Several pieces of evidence highlight that the inoculation of plants with PGPR can have considerable effects on plant at both physiological and molecular levels, suggesting the possibility that soil biota could stimulate plants being more efficient in retrieving nutrients from soil and coping with abiotic stresses.

Reactive oxygen species and antioxidant machinery in abiotic stress tolerance in crop plants
TL;DR: The biochemistry of ROS and their production sites, and ROS scavenging antioxidant defense machinery are described, which protects plants against oxidative stress damages.
Journal ArticleDOI
Plant-growth-promoting rhizobacteria.
TL;DR: This review restricts itself to bacteria that are derived from and exert this effect on the root and generally designated as PGPR (plant-growth-promoting rhizobacteria), which can be direct or indirect in their effects on plant growth.

Organic acids in the rhizosphere: a critical review
TL;DR: In this article, a review of the role of organic acids in rhizosphere processes is presented, which includes information on organic acid levels in plants (concentrations, compartmentalisation, spatial aspects, synthesis), plant efflux (passive versus active transport, theoretical versus experimental considerations), soil reactions (soil solution concentrations, sorption) and microbial considerations (mineralization).
