Root Architecture and Plant Productivity [PDF]
Plant Physiology, 1995 Water and nutrient availability limit plant growth in a11 but a very few natural ecosystems. They limit yield in most agricultural ecosystems, and in the United States and other industrialized nations, intensive irrigation and fertilization have generated serious environmental problems.

Rice root genetic architecture: Meta-analysis from a drought QTL database [PDF]
, 2009 During the last 10 years, a large number of quantitative trait loci (QTLs) controlling rice root morphological parameters have been detected in several mapping populations by teams interested in improving drought resistance in rice.

Building a future with root architecture [PDF]
Journal of Experimental Botany, 2018 Unmanaged consumption and climate change are profoundly affecting water resources at a global level. It is therefore vital to understand plant responses to drought and flooding, and to breed crops with greater water use efficiency and resilience. Root system architecture is critically important in this, but understanding how architecture and root ...

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 ...

Osmotic regulation of root system architecture [PDF]
The Plant Journal, 2005 SummaryAlthough root system architecture is known to be highly plastic and strongly affected by environmental conditions, we have little understanding of the underlying mechanisms controlling root system development. Here we demonstrate that the formation of a lateral root from a lateral root primordium is repressed as water availability is reduced ...

To respond or not to respond? Natural variation of root architectural responses to nutrient signals [PDF]
, 2017 The amino acid glutamate (Glu) acts as a fast excitatory neurotransmitter in mammals. Its importance in plant signalling was recognized with the discovery of channel proteins similar to mammalian Glu receptors, as well as distinct changes in root-system ...

Statistical Characterization of the Root System Architecture Model CRootBox
Vadose Zone Journal, 2018 The connection between the parametrization of three-dimensional (3D) root architecture models and characteristic measures of the simulated root systems is often not obvious.

An auxin transport-based model of root branching in Arabidopsis thaliana. [PDF]
PLoS ONE, 2008 Root architecture is a crucial part of plant adaptation to soil heterogeneity and is mainly controlled by root branching. The process of root system development can be divided into two successive steps: lateral root initiation and lateral root ...

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 ...

A gene-derived SNP-based high resolution linkage map of carrot including the location of QTL conditioning root and leaf anthocyanin pigmentation [PDF]
, 2014 Purple carrots accumulate large quantities of anthocyanins in their roots and leaves. These flavonoid pigments possess antioxidant activity and are implicated in providing health benefits.
