Light modulation of the gravitropic set-point angle (GSA).

Journal of experimental botany - 1 Feb 2002

Digby J, Firn R D

Abstract excerpt

A study has been made of the means by which light influences the gravitropic set-point angle (GSA) of the nodes of Tradescantia and the hypocotyls of the lazy-2 mutant of tomato. In light-grown Tradescantia there is a light-regulated developmental change in the GSA with the magnitude of this change being dependent on the photon flux density of white light. The photosynthetic inhibitor DCMU abolished the effect of...
