Molecular Perspectives for Lateral Root Formation

About this Research Topic

Root branching, such as the formation of lateral roots (LRs), is an important aspect of establishing root system architecture because it optimizes water and nutrient uptake from the soil environment. In Arabidopsis thaliana, lateral roots are formed from pairs of xylem pole pericycle cells of the main root, which are induced by auxin to acquire founder cell identity to form a lateral root primordium (LRP). Lateral root formation is a complex process involving priming, initiation, patterning, and emergence. The plant hormone auxin is a key player in several stages of lateral root formation. Numerous extrinsic abiotic and biotic factors, such as water availability and nutritional status, also influence lateral root formation.

In the model plant Arabidopsis, significant progress has recently been achieved in elucidating the cellular basis of lateral root formation and the underlying gene regulatory networks that regulate lateral root morphogenesis. It's unclear how environmental signals interact with developmental variables to integrate into the lateral roots' complicated signaling networks. The underlying gene regulatory networks of lateral root formation in cereals, in particular, are still unknown.

This Research Topic aims to present new insights into the molecular, cellular, and environmental control of lateral root development in Arabidopsis and crop models including maize and rice. We welcome submissions of original research papers, reviews, and methods, including (but not limited to) research on the following sub-themes:
- Role of phytohormones in lateral root formation.
- Identification of new regulators in lateral root formation.
- Effects of abiotic/biotic stress on lateral root development.
- Manipulation of lateral roots as agricultural applications

Disclaimer: We welcome submissions of different types of related manuscripts, but descriptive studies lacking significant biological advances would be rejected without peer review.


Keywords: Lateral root formation, Root system architecture, Cellular Basis, Gene regulatory networks, Crop
