IN the growing root the pericycle is the site of the interesting morphogenetic activity, the initiation of lateral root primordia. This tissue also participates in the initiation of vascular cambium, ...

Lateral roots in Arabidopsis arise from specialised cells in the pericycle layer of the primary root and represent a finely tuned developmental process that underpins overall plant architecture.
