Fig. 8From: Molecular Genetics of Rice Root DevelopmentA median longitudinal view of a small lateral root visualized under UV based on cell wall autofluorescence using a two-photon laser scanning microscope. The same pattern as described for the radicle meristem is observed: periclinal divisions for columella initials (red arrows), anticlinal divisions for peripheral root cap initials (white arrows), and three sequential periclinal divisions occur, giving rise to epidermis, exodermis, sclerenchyma, and endodermis (yellow arrows). cc, central cells; en, endodermis; pe, pericycle; sc, sclerenchyma layer; ex, exodermis; ep, epidermis.
