Gravitropism and starch statoliths in an Arabidopsis mutant

The mutant TC7 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 plastic starch has a statolith function in gravity perception. In the pr...
