Plants can reorient their growth direction by sensing organ tilt relative to the direction of
gravity. With respect to gravity sensing in gravitropism, the classic starch statolith hypothesis …

Publisher Summary This chapter discusses the gravitropic sensing, especially from the
perspective of cytology and cell biology. The hypothesis that amyloplasts function in …

The observation that a starchless mutant (TC7) of Arabidopsis thaliana (L.) Heynh. is
gravitropic (T. Caspar and BG Pickard, 1989, Planta 177, 185–197) raises questions about …

Gravitropism is directed growth of a plant or plant organ in response to gravity and can be
divided into the following temporal sequence: perception, transduction, and response. This …

Concerns regarding the reliability of slow-and fast-rotating uni-axial clinostats in simulating
weightlessness have induced the construction of devices considered to simulate …

The starch-statolith theory of gravity reception has been tested with a mutant of Arabidopsis
thaliana (L.) Heynh. which, lacking plastid phosphoglucomutase (EC 2.7. 5.1) activity, does …

The starch statolith hypothesis of gravity sensing in plants postulates that the sedimentation
of statoliths in specialized statocytes (columella cells) provides the means for converting the …

The gravitational field controls plant growth, morphology, and development. However, the
underlying transduction mechanisms are not well understood. Much indirect evidence has …

Gravitropism was studied in roots of wild type (WT) Arabidopsis thaliana (L.) Heynh.(strain
Wassilewskija) and three starch‐deficient mutants that were generated, by T‐DNA …

The cytosolic free calcium concentration of higher plant cells is maintained at about 01 μM
by the action of membrane calcium transporters. These act to remove calcium from the …
