Root growth is mainly determined by cell division and subsequent elongation in the root apical area. Components regulating cell division in root meristematic cells are largely unknown.

Cytological observations showed that mesophyll cells were greatly enlarged, undergoing repeated cell divisions, then forming meristematic mass, from which buds were initiated.
