Fruit softening determines the texture, shelf life, and consumer appeal of grapes, yet its molecular regulation remains ...

这篇综述系统阐述了植物激素生长素（auxin）通过建立局部浓度峰值和梯度调控植物生长发育的最新进展。文章重点解析了PIN介导的细胞间运输结构基础，揭示了两种非转录调控机制：细胞内Ca2+瞬变和细胞表面感知介导的超快磷酸化，并探讨了环磷酸腺苷（cAMP ...

In the normal course of events, a plant embryo becomes a seedling and the seedling grows into a plant with all of its organs: roots, stem, leaves and flowers. The foundations for this development are ...

1. When tissue of sugar-cane nodes is submerged for a few minutes in boiling water, a substance is released which suppresses the action of indoleacetic acid in the Avena test (fig. 2). The substance ...

This is a preview. Log in through your library . Abstract Auxin causes elongation growth of plant cells by increasing the plastic extensibility of the cell wall. Putative cellular events involved in ...

The hormone auxin is of central importance for the development of plants. Scientists have now developed a novel sensor that makes the spatial distribution of auxin in the cells of living plants ...

Some 70 years after the plant hormone auxin was discovered, scientists have finally identified one of the proteins targeted by this small molecule (Nature 2005, 435, 441 and 446). The long-awaited ...

A lab-designed hormone may unlock mysteries harbored by plants. By developing a synthetic version of the plant hormone auxin and an engineered receptor to recognize it, Howard Hughes Medical Institute ...

Scientists have uncovered how the plant hormone auxin helps roots bend and downwards towards gravity – a process called gravitropism - even after encountering obstacles in soil.
