Actin depolymerization by Latrunculin B can either suppress or promote root gravitropism, depending on the developmental stages in Arabidopsis [PDF]
Plant Signaling & BehaviorRoot gravitropism enables plants to optimize water and nutrient uptake, with actin filaments playing a key regulatory role. However, the effects of F-actin depolymerization on gravitropism have been inconsistent. Here, we show that actin depolymerization

The Ca2+ pump inhibitor, thapsigargin, inhibits root gravitropism in Arabidopsis thaliana [PDF]
Biological Research, 2006 Thapsigargin, a specific inhibitor of most animal intracellular SERCA-type Ca2+ pumps present in the sarcoplasmic/endoplasmic reticulum, was originally isolated from the roots of the Mediterranean plant Thapsia gargancia L. Here, we demonstrate that this

Striking the Right Chord: Signaling Enigma during Root Gravitropism [PDF]
Frontiers in Plant Science, 2017 Plants being sessile can often be judged as passive acceptors of their environment. However, plants are actually even more active in responding to the factors from their surroundings. Plants do not have eyes, ears or vestibular system like animals, still

A unifying modeling of plant shoot gravitropism with an explicit account of the effects of growth [PDF]
, 2014 Gravitropism, the slow reorientation of plant growth in response to gravity, is a major determinant of the form and posture of land plants. Recently a universal model of shoot gravitropism, the AC model, was presented, in which the dynamics of the tropic

Cellular and physiological functions of SGR family in gravitropic response in higher plants [PDF]
Journal of Advanced ResearchBackground: In plants, gravity directs bidirectional growth; it specifies upward growth of shoots and downward growth of roots. Due to gravity, roots establish robust anchorage and shoot, which enables to photosynthesize.

Enhanced Labeling Techniques to Study the Cytoskeleton During Root Growth and Gravitropism [PDF]
, 2005 Gravity effects the growth and development of all living organisms. One of the most obvious manifestations of gravity's effects on biological systems lies in the ability of plants to direct their growth along a path that is dictated by the gravity vector

Brassinosteroid control of shoot gravitropism interacts with ethylene and depends on auxin signaling components [PDF]
, 2012 Premise of the study: To reach favorable conditions for photosynthesis, seedlings grow upward when deprived of light upon underground germination. To direct their growth, they use their negative gravitropic capacity.
