“…Crops grown in contaminated soil accumulate heavy metals in edible parts. The consumption of these contaminated edible parts leads to the migration of heavy metals in the food chain causing a serious threat to human life as well as the ecosystem (Shukla et al, 2017).…”

Abiotic stresses detrimentally affect both plant and soil health, threatening food security in an ever-increasing world population. Sustainable agriculture is necessary to augment crop yield with simultaneous management of stresses. Limitations of conventional bioinoculants have shifted the focus to more effective alternatives. With the realization of the potential of rhizospheric microbiome engineering in enhancing plant's fitness under stress, efforts have accelerated in this direction. Though still in its infancy, microbiome-based engineering has gained popularity because of its advantages over the microbe-based approach. This review briefly presents major abiotic stresses afflicting arable land, followed by an introduction to the conventional approach of microbe-based enhancement of plant attributes and stress mitigation with its inherent limitations. It then focuses on the significance of the rhizospheric microbiome and possibilities of harnessing its potential by its strategic engineering for stress management. Further, success stories related to two major approaches of microbiome engineering (generation of synthetic microbial community/consortium, and host-mediated artificial selection) pertaining to stress management have been critically presented. Together with bringing forth the challenges associated with the wide application of rhizospheric microbiome engineering in agriculture, the review proposes the adoption of a combinational scheme for the same, bringing together ecological and reductionist approaches for improvised sustainable agricultural practices.

Rapid global modernization, urbanization, industrialization, and frequent natural processes release toxic heavy metals into the environment such as mercury (Hg), lead (Pb), cadmium (Cd), arsenic (As) and selenium (Se). In the present scenario, soil and water ecosystems are the main environmental alarms. The remediation of contaminated soils and water ecosystems with appropriate approaches is urgently needed. Physical remediation strategies are conventional, expensive, and nonspecific. Phytoremediation is an eco-friendly and fast-growing approach that are accomplished because of uptake of large quantities of toxic heavy metals from the environment. Since, plants are slow-growing and have low biomass that urgently needs to be bioengineered for high biomass. On the other hand, biotechnology helps to identify and isolate the specific gene coding for heavy metal resistance tolerance in plants. Moreover, molecular cloning and the manifestation of heavy metal accumulator genes and degrading enzyme coding genes displayed enhanced remediation rates, which will make the process for large-scale application to remediate faster contamination soils and water. This review has prominence on biotechnological methods and strategies for remediation of heavy metals and metalloid containment from environments. Furthermore, it focuses on the improvements and implications of phytoremediation as well as their operations and applications to clean up toxic pollutants from environments and to improve phytoremediation efficiency to tolerate different heavy metal pollutants highlights future challenges.
