Auxin-stimulated elongation of apical segments of rice (Oryza sativa L. cv Arborio) coleoptiles occurring in the first 4 hours of treatment has been studied. Cell extension promoted in the first 2 hours by 10 micromolar indole-3-acetic acid (IAA) is specifically auxin-dependent, whereas after 4 hours, elongation also depends on endogenous production of ethylene. Similar to other systems, rice coleoptile cell elongation stimulated by auxin requires continuous synthesis of RNA and protein. Two… CONTINUE READING
