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.

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 ...

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 ...

Hormone interactions during lateral root formation

Plant Molecular Biology, 2008
Lateral root (LR) formation, the production of new roots from parent roots, is a hormone- and environmentally-regulated developmental process in higher plants. Physiological and genetic studies using Arabidopsis thaliana and other plant species have revealed the roles of several plant hormones in LR formation, particularly the role of auxin in LR ...

Dynamic control of lateral root positioning

Current Opinion in Plant Biology, 2017
In dicot root systems, lateral roots are in general regularly spaced along the longitudinal axis of the primary root to facilitate water and nutrient uptake. Recently, recurrent programmed cell death in the root cap of the growing root has been implicated in lateral root spacing.

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.

Cytokinin inhibits lateral root initiation but stimulates lateral root elongation in rice (Oryza sativa)

Journal of Plant Physiology, 2005
Research in lateral root (LR) development mainly focuses on the role of auxin. This article reports the effect of cytokinins (kinetin and trans-zeatin) on LR formation in rice (Oryza sativa L.). Our results showed that cytokinin has an inhibitory effect on LR initiation and stimulatory effect on LR elongation.

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

Breakout — lateral root emergence in Arabidopsis thaliana

Current Opinion in Plant Biology, 2018
Lateral roots are determinants of plant root system architecture. Besides providing anchorage, they are a plant's means to explore the soil environment for water and nutrients. Lateral roots form post-embryonically and initiate deep within the root. On its way to the surface, the newly formed organ needs to grow through three overlying cell layers; the
