Trace elements in plants

TL;DR: This review briefly summarizes the current knowledge of micronutrients in plants and presents some new speculations on the mechanisms ofmicronutrient uptake and translocation in plants.

TL;DR: In this paper, four basic models for the control of shoot: root ratio (S: R): (a) allometric models, proposing a fixed ratio of shoot growth rate to root growth rate; (b) functional equilibrium models, based on the ratio of shooter activity to root activity; (c) the Thornley model based on carbon and nitrogen uptake and transport, and (d) hormone models, generally suggesting the root produces a hormone that controls the shoot and vice versa.

TL;DR: In this article, the authors present the results of studies on the recent developments in the utilization of plant growth promoting rhizobacteria for direct application in soils contaminated with heavy metals under a wide range of agro-ecological conditions with a view to restore contaminated soils and consequently, promote crop productivity in metal-polluted soils across the globe and their significance in phytoremediation.

TL;DR: Differential tolerance of plant genotypes exposed to zinc toxicity is a promising approach to enrich the authors' understanding of zinc tolerance in plants and may help in interdisciplinary studies to assess the ecological significance of metal stress.
