TL;DR
It is found that cytokinin inhibits anchor root formation with rising nitrate, and data point toward a mechanism by which nitrate controls a previously underappreciated aspect of nitrate-dependent root architecture driven by anchor roots.
Low nitrogen (LN) and high salt stress are major constraints for plant growth and development. Under LN stress, plants typically show root elongation to increase nitrogen foraging from the rhizosphere, whereas high salt levels cause inhibition of root growth to avoid salinity stress-induced toxicity. To date, mechanism...
Findings identify cytokinin as a key regulator of root specific setpoint angles within a root system architecture, with potential implications for optimizing crop resource acquisition and yield.
Lateral roots (LRs) are important components of plant root systems, determining the robustness of root system architecture and influencing water uptake efficiency. Enhancing the phenotypic plasticity of LRs is key to improving crop production under fluctuating environmental conditions. In this study, we identified ANCH...
It is demonstrated that salt stress markedly inhibits root growth in tobacco, while exogenous auxin application effectively alleviated this inhibitory effect, thus offering a promising genetic target for engineering salt-tolerant crops.
ABSTRACT The root of land plants is a remarkably adaptive organ. Unlike the shoot with its main functions in light harvesting and photosynthesis, sexual reproduction and diaspore distribution, the root explores the soil for nutrient resources and water, while preferably avoiding zones of unfavorable conditions. Roots r...
