Progress in Study of Auxin Signaling in Plant Lateral Root Development
Roots are important to plants for uptake of water and nutrients, and lateral roots (LR) are the most important part of the root system.Auxin is a master regulator for LR growth and development.Arabidopsis is a tap root model plant and rice is a fibrous root model crop.This review showed progress in study of auxin signaling in these plants lateral root development.Firstly, this review described models of LR initiation.After that, we reviewed function of Aux/IAAs-mediated auxin signaling in LR growth and development, at the same time we compared LR development in Arabidopsis with that of rice.Finally, we provided prospective views of this field at the end of this review.
