Auxin signaling modulates LATERAL ROOT PRIMORDIUM1 (LRP1) expression during lateral root development in Arabidopsis.

The Plant Journal, 2019
Auxin signaling mediated by various Auxin/Indole-3-Acetic Acid (Aux/IAAs) and AUXIN RESPONSE FACTORs (ARFs) regulate lateral root (LR) development by controlling the expression of downstream genes.

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.

Cytokinin Inhibits Lateral Root Development at the Earliest Stages of Lateral Root Primordium Initiation in Maize Primary Root

Journal of Plant Growth Regulation, 2019
Root architecture is basically controlled by auxin and cytokinin, which antagonize in the formation of lateral roots (LRs) along the primary root (PR) axis. Several mechanisms have been proposed to explain the interaction between these two hormones, cytokinin being the hormone that inhibits LR formation.

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.

Maxillary Lateral Incisor With Two Roots

Australian Endodontic Journal, 2001
ABSTRACTVariations in root canal morphology can lead to complications in endodontic treatment. A case of a maxillary lateral incisor with two roots is reported.

Patterns of variability in the diameter of lateral roots in the banana root system

New Phytologist, 2005
The relative importance of root system structure, plant carbon status and soil environment in the determination of lateral root diameter remains unclear, and was investigated in this study. Banana (Musa acuminata) plants were grown at various moderate levels of soil compaction in two distinct experiments, in a field experiment (FE) and in a glasshouse ...

Root architecture: Influence of metameric organization and emission of lateral roots

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2006
Abstract It has yet to be established whether or not root architecture results from a metameric organization similar to that recognizable in the stem. To address this question, we have reviewed the data on the major cytological, histological and anatomical events underlying root development and on the intrinsic factors controlling these events.

FERONIA regulates auxin‐mediated lateral root development and primary root gravitropism

FEBS Letters, 2018
The Arabidopsis FERONIA (FER) receptor kinase is a key hub of cell signaling networks mediating various hormone, stress, and immune responses. Previous studies have shown that FER functions correlate with auxin responses, but the underlying molecular ...
