Red light-induced suppression of gravitropism in moss protonemata.

Advances in space research : the official journal of the Committee on Space Research (COSPAR) - 1 Jan 1999

Kern V D, Sack F D

Abstract excerpt

Moss protonemata are among the few cell types known that both sense and respond to gravity and light. Apical cells of Ceratodon protonemata grow by oriented tip growth which is negatively gravitropic in the dark or positively phototropic in unilateral red light. Phototropism is phytochrome-mediated. To determine whether any gravitropism persists during irradiation, cultures were turned at various angles with...
