Gravitropism and starch statoliths in an Arabidopsis mutant.
Planta - 1 Jul 1991
Saether N, Iversen T H
Abstract excerpt
The mutant TC 7 of Arabidopsis thaliana (L.) Heynh. has been reported to be starch-free and still exhibit root gravitropism (T. Caspar and B. G. Pickard 1989, Planta 177, 185-197). This is not consistent with the hypothesis that plastid starch has a statolith function in gravity perception. In the present study, initial light microscopy using the same mutant showed apparently starch-free statocytes. However,...
