An automated method for root system architecture reconstruction from 3D volume datasets obtained from magnetic resonance imaging is developed and validated with a 3D semi-manual reconstruction using virtual reality and a 2D reconstruction using SmartRoot (Lobet et al., 2011). It is tested on the basis of a MRI image of a 25 days old lupin grown in natural sand with a resolution of 0.39× 0.39× 1...

Root system architecture (RSA) plays an important role in plant development and survival. The ability to accurately model and quantify properties of root architecture is fundamental for sustainability studies, crop improvement, and studies of plant-microbal interactions. Existing methods to model RSA either require a dense set of images or rely on 3D scanning methods for dense reconstruction. I...

Arabidopsis thaliana has been an excellent model system for molecular genetic approaches to development and physiology. More recently, the potential of studying various accessions collected from diverse habitats has been started to exploit. Col-0 has been the best-studied accession but we now know that several traits show significant divergences among them. In this work, we focused in the root ...

Root system growth and development is highly plastic and is influenced by the surrounding environment. Roots frequently grow in heterogeneous environments that include interactions from neighboring plants and physical impediments in the rhizosphere. To investigate how planting density and physical objects affect root system growth, we grew rice in a transparent gel system in close proximity wit...

BACKGROUND Phosphorus (P) is an essential element for plant growth and development but it is often a limiting nutrient in soils. Hence, P acquisition from soil by plant roots is a subject of considerable interest in agriculture, ecology and plant root biology. Root architecture, with its shape and structured development, can be considered as an evolutionary response to scarcity of resources. ...

Phosphate (Pi) limitation causes plants to modulate the architecture of their root systems to facilitate the acquisition of Pi. Previously, we reported that the Arabidopsis (Arabidopsis thaliana) SUMO E3 ligase SIZ1 regulates root architecture remodeling in response to Pi limitation; namely, the siz1 mutations cause the inhibition of primary root (PR) elongation and the promotion of lateral roo...

To complement N2 fixation through symbiosis, legumes can efficiently acquire soil mineral N through adapted root architecture. However, root architecture adaptation to mineral N availability has been little studied in legumes. Therefore, this study investigated the effect of nitrate availability on root architecture in Medicago truncatula and assessed the N-uptake potential of a new highly bran...
