2 Figure 1 Environmental Regulation of Endodermal and Exodermal Suberization Endodermal (A) and exodermal (B) cells undergo two steps of differentiation by first the formation of Casparian strip (CS) and then the deposition of suberin lamellae. (A) Arabidopsis thaliana (Col-0) root cross-section. Suberization of endodermis is affected by different environmental stimuli. It is positively regulated by deficiency in K, S, and NaCl excess via abscisic acid (ABA) and negatively regulated during deficiency in Fe, Zn, and Mn via ethylene (C2H4). Image provided by Miguel De Lucas. (B) Oryza sativa cv. Nipponbare root cross-section. Suberization is induced by an excess of NaCl and oxygen deprivation.
