The endodermis and shoot gravitropism

Trends in Plant Science, 1999
Shoots and roots of higher plants exhibit negative and positive gravitropism, respectively. A variety of gravitropic mutants have recently been isolated from Arabidopsis, the characterization of which demonstrates that the molecular mechanisms of the gravitropic responses in roots, hypocotyls and inflorescence stems are different.

Role of Endodermal Cell Vacuoles in Shoot Gravitropism

Journal of Plant Growth Regulation, 2002
In higher plants, shoots and roots show negative and positive gravitropism, respectively. Data from surgical ablation experiments and analysis of starch deficient mutants have led to the suggestion that columella cells in the root cap function as gravity perception cells.

Effect of shoot tip and leaf removal on gravitropism in pea

Journal of Plant Physiology, 1997
Intact, light-grown pea (Pisum sativum L. cv. Alaska) seedlings were subjected to continuous horizontal gravistimulation and their growth and bending response compared with seedlings whose shoot tip and youngest leaf had been excised and with seedlings to which a counterweight to replace the mass of the decapitated tissue was added. While all seedlings

A single amino acid substitution in MdLAZY1A dominantly impairs shoot gravitropism inMalus

Plant Physiology, 2023
AbstractPlant architecture is one of the most important factors that determines crop yield potential and productivity. In apple (Malus), genetic improvement of tree architecture has been challenging due to a long juvenile phase and their growth as complex trees composed of a distinct scion and a rootstock.

Overexpression of acetylcholinesterase gene in rice results in enhancement of shoot gravitropism

Biochemical and Biophysical Research Communications, 2015
Acetylcholine (ACh), a known neurotransmitter in animals and acetylcholinesterase (AChE) exists widely in plants, although its role in plant signal transduction is unclear. We previously reported AChE in Zea mays L. might be related to gravitropism based on pharmacological study using an AChE inhibitor.

Effects of LAZY family genes on shoot gravitropism in Lotus japonicus

Plant Science
Plant architecture is an important agronomic trait to determine the biomass and sward structure of forage grass. The IGT family plays a pivotal role in plant gravitropism, encompassing both the gravitropic response and the modulation of plant architecture.

Inhibition of the gravitropic bending response of flowering shoots by salicylic acid

Plant Science, 2003
The upward gravitropic bending of cut snapdragon, lupinus and anemone flowering shoots was inhibited by salicylic acid (SA) applied at 0.5 mM and above. This effect was probably not due to acidification of the cytoplasm, since other weak acids did not inhibit bending of snapdragon shoots.

Altered gravitropic response, amyloplast sedimentation and circumnutation in the Arabidopsis shoot gravitropism 5 mutant are associated with reduced starch levels

Plant Molecular Biology, 2008
Plants have developed sophisticated gravity sensing mechanisms to interpret environmental signals that are vital for optimum plant growth. Loss of SHOOT GRAVITROPISM 5 (SGR5) gene function has been shown to affect the gravitropic response of Arabidopsis inflorescence stems.

The role of actin filaments in the gravitropic response of snapdragon flowering shoots

Planta, 2003
The involvement of the actin and the microtubule cytoskeleton networks in the gravitropic response of snapdragon ( Antirrhinum majus L.) flowering shoots was studied using various specific cytoskeleton modulators. The microtubule-depolymerizing drugs tested had no effect on gravitropic bending.
