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

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.

LAZY1 Controls Rice Shoot Gravitropism Through Regulating Polar Auxin Transport [PDF]

Cell Research, 2007
Tiller angle of rice (Oryza sativa L.) is an important agronomic trait that contributes to grain production, and has long attracted attentions of breeders for achieving ideal plant architecture to improve grain yield. Although enormous efforts have been made over the past decades to study mutants with extremely spreading or compact tillers, the ...

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.

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.

Genetic evidence that the endodermis is essential for shoot gravitropism in Arabidopsis thaliana

The Plant Journal, 1998
Summary Shoots of higher plants exhibit negative gravitropism. However, little is known about the mechanism or site of gravity perception in shoots. We have identified two loci that are essential for normal shoot gravitropism in Arabidopsis thaliana.

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.

Hormonal Regulation of the Gravitropic Response in Pulvini of Grass Shoots

1985
The gravitropic responses in plants can be visualized most easily in terms of three distinct phases: gravity perception, transduction, and cellular response. The second one, transduction, involves the development of the hormonal asymmetry which has been experimentally verified for both roots and shoots that have been gravistimulated.
