Local and systemic regulation of plant root system architecture and symbiotic nodulation by a receptor-like kinase. [PDF]
PLoS Genetics, 2014 In plants, root system architecture is determined by the activity of root apical meristems, which control the root growth rate, and by the formation of lateral roots. In legumes, an additional root lateral organ can develop: the symbiotic nitrogen-fixing

HY5 Contributes to Light-Regulated Root System Architecture Under a Root-Covered Culture System
Frontiers in Plant Science, 2019 Light is essential for plant organogenesis and development. Light-regulated shoot morphogenesis has been extensively studied; however, the mechanisms by which plant roots perceive and respond to aboveground light are largely unknown, particularly because

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]
, 2009 We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A

Getting to the roots of it: Genetic and hormonal control of root architecture
Frontiers in Plant Science, 2013 Root system architecture (RSA)--the spatial configuration of a root system--is an important developmental and agronomic trait, with implications for overall plant architecture, growth rate and yield, abiotic stress resistance, nutrient uptake, and ...

Soil compaction and the architectural plasticity of root systems [PDF]
Journal of Experimental Botany, 2019 We present examples of root plasticity in response to soil compaction and discuss their role in plant performance. Subsequently, we propose a plastic ideotype for soil compaction tolerance.

Iterative image segmentation of plant roots for high-throughput phenotyping
Scientific Reports, 2022 Accurate segmentation of root system architecture (RSA) from 2D images is an important step in studying phenotypic traits of root systems. Various approaches to image segmentation exist but many of them are not well suited to the thin and reticulated ...

Phenotyping and modeling of root hydraulic architecture reveal critical determinants of axial water transport [PDF]
, 2022 International audienceWater uptake by roots is a key adaptation of plants to aerial life. Water uptake depends on root system architecture (RSA) and tissue hydraulic properties that, together, shape the root hydraulic architecture. This work investigates
