Hydrotropism - Wikipedia
Hydrotropism (hydro- "water"; tropism "involuntary orientation by an organism, that involves turning or curving as a positive or negative response to a stimulus") [1] is a plant's growth response in which the direction of growth is determined by a stimulus or …
Hydrotropism – Definition, Meaning with Examples & Diagram
2023年2月9日 · Hydrotropism is a type of tropic movement by which some plant parts, specifically root and stem, tend to move towards or away from water stimulus. The term ‘hydrotropism’ is a combination of two words, ‘hydro’ and ‘tropism’.
Hydrotropism Definition and Examples - Biology Online
2020年1月26日 · Hydrotropism is a form of tropism characterized by the growth or movement response of a cell or an organism to moisture or water. The response may be positive or negative. A positive hydrotropism is one in which the organism tends to grow towards moisture whereas a negative hydrotropism is when the organism grows away from it.
Hydrotropism: how roots search for water - Oxford Academic
2018年2月26日 · Hydrotropism allows roots to grow actively towards water sources which may be located in any direction. Understanding and modifying this response in plants should be considered as an additional strategy to pursue the goal of sustainable water use in agriculture.
Root hydrotropism is controlled via a cortex-specific growth
2017年5月8日 · Hydrotropism allows roots to forage for water, a process known to depend on abscisic acid (ABA) but whose molecular and cellular basis remains unclear. Here we show that hydrotropism still...
Hydrotropism mechanisms and their interplay with gravitropism
2024年2月23日 · Plants 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.
Hydrotropism - an overview | ScienceDirect Topics
Hydrotropism: a tropic response independent of auxin relocalization. In addition to responding to light and gravity, plant roots are hydrotropic: they sense differences in water potential in the local environment and direct their growth accordingly. The molecular details underlying this process are just becoming clear.
Hydrotropism: Understanding the Impact of Water on Plant
2023年2月1日 · Hydrotropism is the movement or growth of a plant towards water. It is a type of tropism, or directional growth response, that is triggered by water. Plants are able to detect water through various stimuli, including changes in moisture levels and changes in water potential.
Hydrotropism Definition & Meaning - Merriam-Webster
The meaning of HYDROTROPISM is a tropism (as in plant roots) in which water or water vapor is the orienting factor.
Hydrotropism: root growth responses to water - Cell Press
Recent genetic analysis of hydrotropism in Arabidopsis has provided new insights about the mechanisms that the root cap uses to perceive and respond simultaneously to moisture and gravity signals.
