Auxin plays a central role in plant life. The hormone regulates various processes, from embryonic development to the formation of roots and the directional growth in response to light and gravity.

Auxin-binding protein 1 (ABP1), identified more than 40 years ago, is required for the activation of plasma membrane-associated ROPs (RHO-like GTPases from plants), which regulate cytoskeletal ...

There are veins in plants that move nutrients and other important molecules around. These veins have to be carefully organized, and the plant hormone called auxin helps do this by migrating from cell ...

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 ...

During the 1960s a wide range of studies provided an information base that led to the suggestion that auxin-regulated cell processes - especially cell elongation - may be mediated by auxin-regulated ...

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 ...

Fruit ripening, root branching, and even the flowering of some species are all nurtured by auxin, the plant world's most legendary hormone. Now researchers have finally figured out how this indole ...

New research appears to answer an old question about how the remarkable hormone Auxin works. Auxin is a sort of super-hormone that is the key to making plants grow. Two scientific teams--one in ...

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 ...

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 biosensor visualizes redistribution dynamics of the plant hormone auxin in living cells. A team of scientists at the Max Planck Institute for Developmental Biology in Tübingen and the University of ...
