Initial phases of gravity-induced lateral auxin transport and geotropic curvature in corn coleoptiles

Abstract

Wild-type corn coleoptiles showed an initial downward bending upon transfer from the vertical to the horizontal position. Strong upward curvature started only 15–30 min after the begin of horizontal exposure. Little, if any at all, initial downward geotropic bending was found with amylomaize coleoptiles at 1 X g. With stronger stimuli (10 or 20 X g) the… (More)
