Gravitropism in Higher Plant Shoots [PDF]
Plant Physiology, 1988 An alternative to the Cholodny-Went, auxin-transport hypothesis of gravitropic stem bending was proposed as early as 1958, suggesting that gravistimulation induces changes in sensitivity to auxin, accounting for differential growth and bending.

Gravitropism in Higher Plant Shoots [PDF]
Plant Physiology, 1986 Ethylene at 1.0 and 10.0 cubic centimeters per cubic meter decreased the rate of gravitropic bending in stems of cocklebur (Xanthium strumarium L.) and tomato (Lycopersicon esculentum Mill), but 0.1 cubic centimeter per cubic meter ethylene had little effect.

SCFTIR1/AFB Auxin Signaling for Bending Termination during Shoot Gravitropism [PDF]
Plant Physiology, 2020 TIR1/AFB signaling is required and sufficient for auxin-mediated PIN3 re-polarization and shoot gravitropic bending termination.

Elucidating the Genetic Basis of Columnar Upright Architecture in Populus Through CRISPR Disruption of TILLER ANGLE CONTROL1. [PDF]
Plant Biotechnol JABSTRACT Narrow or upright branch angles in shoots and leaves lead to columnar, upright‐growing tree architectures, as observed in various tree species such as Lombardy poplar (Populus nigra var. italica). However, the genetic mechanism underlying this unique growth habit in Lombardy poplar has not yet been elucidated.

Gravitropism in Higher Plant Shoots [PDF]
Plant Physiology, 1989 Although the Cholodny-Went model of auxin redistribution has been used to explain the transduction phase of gravitropism for over 60 years, problems are apparent, especially with dicot stems. An alternative to an auxin gradient is a physiological gradient in which lower tissues of a horizontal stem become more sensitive than upper tissues to auxin ...

Characterization of a Novel Creeping Tartary Buckwheat (Fagopyrum tataricum) Mutant lazy1
Frontiers in Plant Science, 2022 Gravity is known as an important environmental factor involved in the regulation of plant architecture. To identify genes related to the gravitropism of Tartary buckwheat, a creeping line was obtained and designated as lazy1 from the mutant bank by 60Co ...

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 ...

Stochastic processes in gravitropism [PDF]
, 2014 In this short review we focus on the role of noise in gravitropism of plants – the reorientation of plants according to the direction of gravity. We briefly introduce the conventional picture of static gravisensing in cells specialized in sensing.

A unified model of shoot tropism in plants: photo-, gravi- and Propio-ception. [PDF]
PLoS Computational Biology, 2015 Land plants rely mainly on gravitropism and phototropism to control their posture and spatial orientation. In natural conditions, these two major tropisms act concurrently to create a photogravitropic equilibrium in the responsive organ.

Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica
Frontiers in Bioscience-Landmark, 2021 Background: Plants have evolved the dual capacity for maximizing light assimilation through stem growth (phototropism) and maximizing water and nutrient absorption through root growth (gravitropism).
