A type of cell involved in it secretes waxy suberin.
This process, which is stimulated by zeatin, is induced by aleurone cells secreting alpha-amylase. A type of cell involved in it secretes waxy suberin. In some roots, this process occurs in the pericycle. This process is induced by cytokinins and inhibited by abscisic acid. It is mostly vertical in (*) apical dominance. The "secondary" type of it follows an annual cycle, making dendrochronology possible. This process occurs in the cambium and meristem. It occurs in the direction of light in phototropism. For 10 points, name this process that is induced by gibberellins and auxins in plants, and by HGH in humans.
