Hydrotropism mechanisms and their interplay with gravitropism
The Plant JournalSUMMARYPlants partly optimize their water recruitment from the growth medium by directing root growth toward a moisture source, a phenomenon termed hydrotropism. The default mechanism of downward growth, termed gravitropism, often functions to counteract hydrotropism when the water‐potential gradient deviates from the gravity vector.

Biologia Plantarum, 2013 In conifers, relationship between ethylene and the response to inclination are not well understood. The aim of this work was to study the consequence for the application of 2-chloroethyl phosphonic acid (ethephon), compound able to release ethylene, in ...

PLoS ONE, 2019 Perception of inclination in the gravity field and perception of light direction are two important environmental signals implicated in the control of plant shape and habit. However, their quantitative study in light-grown plants remains a challenge.

A unifying modeling of plant shoot gravitropism with an explicit account of the effects of growth [PDF]
, 2014 Gravitropism, the slow reorientation of plant growth in response to gravity, is a major determinant of the form and posture of land plants. Recently a universal model of shoot gravitropism, the AC model, was presented, in which the dynamics of the tropic

, 1998 The apical hook that forms at the apex of most dicotyledonous seedlings during germination has in the past been variously described either as the consequence of positive gravitropism or as an autonomous process.

Gravitropism in the Statolith-Free Internodal Cells of Chara Corallina [PDF]
, 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 ...

Suppression of asymmetric acid efflux and gravitropism in maize roots treated with auxin transport inhibitors of sodium orthovanadate [PDF]
, 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.

Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics
Advanced ScienceThe pervasive prevalence of nanoplastics in environment poses a challenge that threatens ecosystem and agricultural production. Despite their ubiquity, the determinants of nanoplastics phytotoxicity and the mechanisms through which plants defend against ...
