Resumen:

Lateral roots increase the volume of soil reached by the root, provide anchorage, and participate in water and nutrient uptake and transport. The number and location of lateral roots depends on their continued initiation and, collectively, is a major determinant of root system architecture. In seed plants, lateral root initiation (LRI) typically takes place close to the meristematic region in the root tip in an internal cell layer called the pericycle. Current hypotheses as to how pericycle cells become committed to forming lateral roots are discussed, along with the cellular basis and genetic control of LRI. Examples of the ecological, agricultural, and economic importance of LRI are also presented. © 2017 Elsevier Ltd. All rights reserved.
