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.

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 ...

Impact of root system architecture on rhizosphere and root microbiome
Rhizosphere, 2018Abstract The root system influences plant fitness, health, and productivity via its phenotypic traits (phenes) such as root length, biomass, density, volume, and surface area. Although these traits differentially impact the release of 20 to 80% of total photosynthates as root exudates, their role in influencing microbial communities in the ...

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.

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 ...

Why model root system architecture?
2000In this short discussion, I shall attempt to classify some of the various models of root system architecture according to the different purposes they can serve. A major objective, which is recurrent in many modelling approaches, was to provide better representations of the root system as an input for uptake models or crop models.

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.

A plant root system architectural taxonomy: A framework for root nomenclature
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2010Abstract Research into root system morphology over the last two centuries has developed a diverse set of terminologies that are difficult to apply consistently across species and research specialties. In response to a need for better communication, a workshop held by the International Society for Root Research established some nomenclature standards ...
