Researchers at University of Tsukuba have demonstrated that tomato mutants lacking the SlIAA9 gene, an auxin signaling ...

A research team has uncovered how auxin helps prepare floral nectaries for later nectar release in Platycodon grandiflorus, showing that external auxin treatment triggers strong starch buildup in ...

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.

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 ...

Plants can't move to escape the heat like humans can; they are forced to adapt. As temperatures fluctuate, one key survival ...

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 ...

Scientists have found that the plant hormone auxin governs the change from cell division at shoot tips to the development of female parts of a flower. Auxin levels are themselves controlled by the ...

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 ...

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 ...

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 ...
