来自中科院植物研究所，德国波恩大学等处的研究人员发表了题为“The Signal Transducer NPH3 Integrates the Phototropin1 Photosensor with PIN2-Based Polar Auxin Transport in Arabidopsis Root ...

Phototropin (phot) receptor kinases play important roles in promoting plant growth by controlling light-capturing processes, such as phototropism. Phototropism is mediated through the action of ...

本研究揭示了拟南芥Arabidopsis halleri通过花梗的向光性（phototropism）和向重力性（gravitropism）协同调控花器官定向的分子机制。研究人员结合田间观测、生长室实验和转录组分析，发现花梗通过生长素（auxin）介导的细胞壁重构实现天气依赖性运动——晴天向上 ...

This is a preview. Log in through your library . Abstract Auxin efflux carrier PIN-FORMED (PIN) proteins are thought to have central roles in regulating asymmetrical auxin translocation during tropic ...

Plants are fixed at a place with their roots in the ground, so they cannot move from one place to another. That is plant do not show movement of the entire body. However, movement of the individual ...

Scientists reported molecular-level discoveries about the mechanisms of phototropism, the directional growth of plants toward or away from light. Phototropism is initiated when photoreceptors in a ...

PICATINNY ARSENAL, N.J. (Nov. 27, 2013) -- Most of us are familiar with photosynthesis, but photosynthesis would not be possible without another, lesser known, process called phototropism.

The way a young sunflower turns its bright yellow head to follow the movements of the Sun across the sky each day can be quite dramatic, in terms of plant activity. Now scientists have been surprised ...
