Effects of abscisic acid and xanthoxin on elongation and gravitropism in primary roots of zea mays

, 2018
We examined the involvement of abscisic acid (ABA) and xanthoxin (Xan) in maize root gravitropism by (1) testing the ability of ABA to allow positive gravitropism in dark-grown seedlings of the maize cultivar LG11, a cultivar known to require light for ...

Root system architecture and gravitropism in the oil palm

, 2000
The oil palm (Elaeis guineensis Jacq.) has a root system consisting of primary (or order 1) roots, which are either orthogravitropic (R1 VD, with positive gravitropism) or diagravitropic (R1 H). Their statenchyma have very similar characteristics (mainly

Gravitropism in the Statolith-Free Internodal Cells of Chara Corallina

, 2001
The giant internodal cells of Chara corallina exhibit a well-documented gravity-induced polarity of cytoplasmic streaming. In order to determine whether these cells also exhibit a gravitropism, we grew Chara in small containers that could be reoriented ...

Arabidopsis P-Glycoprotein19 Participates in the Inhibition of Gravitropism by Gravacin

, 2007
SummaryATP-binding cassette (ABC) transporters have been implicated in a multitude of biological pathways. In plants, some ABC transporters are involved in the polar transport of the plant hormone auxin and the gravitropic response.

Suppression of asymmetric acid efflux and gravitropism in maize roots treated with auxin transport inhibitors of sodium orthovanadate

, 1982
In gravitropically stimulated roots of maize (Zea mays L., hybrid WF9 x 38MS), there is more acid efflux on the rapidly growing upper side than on the slowly growing lower side.

Low Phosphate Alters Lateral Root Setpoint Angle and Gravitropism

, 2013
Premise of the study: Lateral roots, responsible for water and nutrient uptake, maintain nonvertical angles throughout development. Soil phosphate is one limiting nutrient for plant growth that is known to induce changes to root system architecture, such

Rapid translocation of NGR proteins driving polarization of PIN-activating D6 protein kinase during root gravitropism

eLife
Root gravitropic bending represents a fundamental aspect of terrestrial plant physiology. Gravity is perceived by sedimentation of starch-rich plastids (statoliths) to the bottom of the central root cap cells.

ABP1/ABL3-TMK1 cell-surface auxin signaling targets PIN2-mediated auxin fluxes for root gravitropism

International audiencePhytohormone auxin and its directional transport mediate much of the remarkably plastic development of higher plants. Positive feedback between auxin signaling and transport is a prerequisite for (1) self-organizing processes ...

Interaction of nitric oxide with auxin and ethylene signalling in Arabidopsis root gravitropism [PDF]

Gravitropism is required for the appropriate alignment of the plant root and shoot. According to the Cholodny-Went hypothesis, gravity induces asymmetric accumulation of auxin in the lower side of the root tissue. More recent studies on root gravitropism

Comparative effects of auxin and abscisic acid on growth, hydrogen ion efflux and gravitropism in primary roots of maize

, 1984
In order to test the idea that auxin action on root growth may be mediated by H(+) movement, the correlation of auxin action on growth and H(+) movement in roots was examined along with changes in H(+) efflux patterns associated with the asymmetric ...
