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

Root Architecture Responses: In Search of Phosphate [PDF]

Plant Physiology, 2014
Soil phosphate represents the only source of phosphorus for plants and, consequently, is its entry into the trophic chain. This major component of nucleic acids, phospholipids, and energy currency of the cell (ATP) can limit plant growth because of its low mobility in soil.

Phenotyping Tomato Root Developmental Plasticity in Response to Salinity in Soil Rhizotrons

Plant Phenomics, 2021
Plants have developed multiple strategies to respond to salt stress. In order to identify new traits related to salt tolerance, with potential breeding application, the research focus has recently been shifted to include root system architecture (RSA ...

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 ...

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.

Arabidopsis Growth-Promotion and Root Architecture Responses to the Beneficial Rhizobacterium Phyllobacterium brassicacearum Strain STM196 Are Independent of the Nitrate Assimilatory Pathway

Plants, 2022
Phyllobacterium brassicacearum STM196, a plant growth-promoting rhizobacterium isolated from roots of oilseed rape, stimulates Arabidopsis growth. We have previously shown that the NRT2.5 and NRT2.6 genes are required for this growth promotion response ...

Nitrate Transporters and Root Architecture

, 2010
Nitrogen (N) is one of the most important limiting factors for plant growth and crop production. The root is the most important organ for acquring soil N that is available as NO 3 − , NH 4 + or amino acids. Soil NO 3 − availability to roots is transient and the concentrations of NO 3 − can rapidly change in response to climatic factors.

RootNav: Navigating Images of Complex Root Architectures     [PDF]

Plant Physiology, 2013
AbstractWe present a novel image analysis tool that allows the semiautomated quantification of complex root system architectures in a range of plant species grown and imaged in a variety of ways. The automatic component of RootNav takes a top-down approach, utilizing the powerful expectation maximization classification algorithm to examine regions of ...

Root System Architecture and Gravitropism in the Oil Palm [PDF]

Annals of Botany, 2000
The oil palm (Elaeis guineensis Jacq.) has a root system consisting of primary (or order 1) roots, which are either orthogravitropic (R1 VD, with positive gravitropism) or diagravitropic (R1 H). Their statenchyma have very similar characteristics (mainly vacuolated, large cells).

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
