Integration of Cell Growth and Asymmetric Division during Lateral Root Initiation in Arabidopsis thaliana.

Abstract excerpt

Lateral root formation determines to a large extent the ability of plants to forage their environment and thus their growth. In Arabidopsis thaliana and other angiosperms, lateral root initiation requires radial cell expansion and several rounds of anticlinal cell divisions that give rise to a central core of small cells, which express different markers than the larger surrounding cells. These small central cells...
