What is the threshold amount of starch necessary for full gravitropic sensitivity?

Advances in space research : the official journal of the Committee on Space Research (COSPAR) - 1 Jan 1998

Abstract excerpt

In preparation for microgravity experiments, we studied the kinetics of gravitropism in seedlings of wild-type (WT) Arabidopsis and three starch-deficient mutants. One of these mutants is starchless (ACG 21) while the other two are intermediate starch mutants (ACG 20 and ACG 27). In root cap cells, ACG 20 and 27 have 51% and 60% of the WT amount of starch, respectively. However, in endodermal cells of the...
