Specification and evolution of lateral roots

Current Biology, 2023
Plants have evolved a remarkable capacity to develop new organs post-embryonically throughout their lifespan. A prime example of this is root branching. Root branching occurs in two ways: dichotomous and lateral branching. The dichotomous branching is the result of the division of the root apical meristem into two daughter meristems, likely through ...

Auxin-Regulated Lateral Root Organogenesis

Cold Spring Harbor Perspectives in Biology, 2021
Plant fitness is largely dependent on the root, the underground organ, which, besides its anchoring function, supplies the plant body with water and all nutrients necessary for growth and development. To exploit the soil effectively, roots must constantly integrate environmental signals and react through adjustment of growth and development.

Lateral Root Regulation

Science Signaling, 2008
A membrane kinase regulates the number of stem cells in the main tip of the root as well as the de novo generation of stem cells in new laterally projecting roots.

Adventitious lateral rooting: the plasticity of root system architecture

Physiologia Plantarum, 2018
Root formation under natural conditions is plastic in response to multiple signals. Recent studies suggested that theWUSCHEL‐RELATED HOMEOBOX11(WOX11)‐mediated adventitious root formation pathway can occur in the primary root (PR) inArabidopsis thaliana, resulting in the production of a specific type of lateral roots (LRs) in response to wounding or ...

Lateral root initiation in Marsilea quadrifolia. I. Origin and histogenesis of lateral roots

Canadian Journal of Botany, 1991
In Marsilea quadrifolia, lateral roots arise from modified single cells of the endodermis located opposite the protoxylem poles within the meristematic region of the parent root. The initial cell divides in four specific planes to establish a fivecelled lateral root primordium, with a tetrahedral apical cell in the centre and the oldest merophytes and

Dissecting Arabidopsis lateral root development

Trends in Plant Science, 2003
Recent studies in the model plant Arabidopsis provide new insight into the regulation of root architecture, a key determinant of nutrient- and water-use efficiency in crops. Lateral root (LR) primordia originate from a subset of pericycle founder cells.

Posterior root tears of the lateral meniscus

Knee Surgery, Sports Traumatology, Arthroscopy, 2014
AbstractPurposeTo summarize and discuss the current knowledge on posterior lateral meniscus root tears.MethodsA comprehensive review of the MEDLINE database was carried out to identify relevant articles using different keywords (e.g. “meniscus root”, “root tear”, “meniscus avulsion”, “radial tear” and “lateral meniscus”).

Lateral condensation stress in root canals

Journal of Endodontics, 1981
A photoelastic model system has been developed for studying the location and magnitude of stresses generated during the lateral condensation of gutta-percha. Standardized and anatomic models of teeth having flared and unflared canal preparations were fabricated.
