Gravitropism in Higher Plant Shoots [PDF]
Plant Physiology, 1984 Cross and longitudinal sections were prepared for light microscopy from vertical control plants (Xanthium strumarium L. Chicago strain), free-bending horizontal stems, plants restrained 48 hours in a horizontal position, and plants restrained 48 hours and then released, bending immediately about 130 degrees .

<i>SHOOT GRAVITROPISM 9</i> links sensory timing to the initial lateral root growth angle. [PDF]
Proc Natl Acad Sci U S APlants strategically respond to gravity and actively set defined growth angles. These gravitropic set-point angles (GSAs) shape the width and depth of the root system, determining soil exploration for water and nutrient uptake ...

PROG1 acts upstream of LAZY1 to regulate rice tiller angle as a repressor
Crop Journal, 2023 Rice tiller angle, as a component of plant architecture, affects rice grain yield via plant density. However, the molecular mechanism underlying rice tiller angle remains elusive.

Sequence of Key Events in Shoot Gravitropism [PDF]
Plant Physiology, 1984 It has recently been shown that asymmetric acid efflux is closely correlated with the gravitropic curvature of plant shoots and roots. The research reported here addresses whether auxin (IAA) redistribution in shoots is the cause or result of asymmetric acid efflux.When abraded sunflower (Helianthus annuus cv Mammoth) hypocotyls are submerged in 20 ...

Gravitropism in Higher Plant Shoots [PDF]
Plant Physiology, 1981 It has long been known that applied ethylene can redirect the gravitropic response, but only occasionally has it been suggested that ethylene normally plays a role in gravitropism. Two inhibitors of ethylene synthesis [Co(2+) and aminoethoxyvinylglycine (AVG)] and two inhibitors of ethylene action (Ag(+) and CO(2)) were shown to delay the gravitropic ...

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.

Arabidopsis shoot gravitropism requires the Mediator coactivator complex [PDF]
, 2022 Gravitropism is a plant response to gravity in directing the growth of its organs, such as the root and the stem. Gravity is sensed by statocytes, unique cells that contain starch-filled amyloplasts, which trigger gravitropic growth response by ...

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.
