Root system architecture in cereals: progress, challenges and perspective [PDF]
Plant Journal, 2022 SUMMARY Roots are essential multifunctional plant organs involved in water and nutrient uptake, metabolite storage, anchorage, mechanical support, and interaction with the soil environment. Understanding of this ‘hidden half’ provides potential for manipulation of root system architecture (RSA) traits to optimize resource use ...

Abstract Plants develop most organs post-embryonically, which allows the incorporation of environmental information into decisions concerning when and where to produce new organs. This developmental plasticity is evident in the plant root system, which in dicotyledonous plants such as Arabidopsis thaliana is mostly comprised of lateral and ...

NO and ROS implications in the organization of root system architecture
Physiologia Plantarum, 2020Over the past decades the role of nitric oxide (NO) and reactive oxygen species (ROS) in signaling and cellular responses to stress has witnessed an exponential trend line. Despite advances in the subject, our knowledge of the role of NO and ROS as regulators of stress and plant growth and their implication in signaling pathways is still partial.

Modelling Root System Growth and Architecture
2000For any complex system, and particularly for the root system interacting with the rest of the plant and the environment, a model can be a helpful tool for synthesising knowledge to produce more global representations and for testing hypotheses on the interacting mechanisms derived from experimental results.

Root system architecture in rice: impacts of genes, phytohormones and root microbiota
3 Biotech, 2022To feed the continuously expanding world's population, new crop varieties have been generated, which significantly contribute to the world's food security. However, the growth of these improved plant varieties relies primarily on synthetic fertilizers, which negatively affect the environment and human health; therefore, continuous improvement is needed

ArchiSimple: A parsimonious model of the root system architecture
2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications, 2012Models of the root system architecture are useful tools for studying the plant soil system, and many of these models have been published during the last decades. They capture several specific and interesting characteristics: (i) they simulate both the structure and spatial distribution of the root system; (ii) they allow a straightforward integration ...

Hidden Branches: Developments in Root System Architecture
Annual Review of Plant Biology, 2007The root system is fundamentally important for plant growth and survival because of its role in water and nutrient uptake. Therefore, plants rely on modulation of root system architecture (RSA) to respond to a changing soil environment. Although RSA is a highly plastic trait and varies both between and among species, the basic root system morphology ...

Modelling Root System Architecture: Experimental Data on Maize Root System Geometry
1991ABSTRACT The arrangement of primary roots around the maize stem and their trajectories in the soil were studied in a deep loamy field with a favourable structure. The angles between roots around the stem were measured in 63 plants. The trajectories of 29 roots visible on profile walls were drawn on horizontal and vertical planes and then digitized ...

Fractal Characterization of Root System Architecture
Functional Ecology, 19921. The fractal dimensions of seedling root systems of two grasses and two dicots growing in situ against glass sheets have been measured using the dividers method. Values were mostly below 1.5. 2. D was little affected by nutrient supply in Trifolium pratense, but differed significantly between four other species. 3.
