In this review, we analyze progress in understanding the mechanisms of root meristem development and function. The formation of embryonic and lateral roots, together with the remarkable regenerative ability of roots, seems to be linked to an auxin-dependent patterning mechanism, the "reflux loop," that can act at least partly independently of cellular context. A major feature of root formation is the production of the "structural initials," the center of the developing root. These cells form an… CONTINUE READING
