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 ...

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 ...

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 ...

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 ...

In plants, it has been clear for a while that maternal signals regulate embryo development. However, the signal itself was unknown -- until now. Plant scientists have now found that a plant hormone ...

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 ...

A team of plant scientists has uncovered how a small yet powerful organ—the rootstock cotyledon—governs the success of graft ...

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 ...

Phytohormones are chemical messengers that regulate the growth of plants and their response to the environment. In land plants, auxin is an important and well-studied phytohormone that affects various ...

Auxin is the most important class of hormones in plants, and its asymmetric distribution pattern in plants regulates the developmental processes of plant cells and tissues, including cell division, ...
