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 ...

The AUXIN RESPONSE FACTORs (ARFs) and the Aux/IAA proteins regulate various auxin responses through auxin perception mediated by the F-box proteins TIR1/AFBs. ARFs are transcription factors that ...

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.

Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be able ...

While pregnancy in humans and seed development in plants look very different, parallels exist - not least that the embryo develops in close connection with the mother. In animals, a whole network of ...

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.

How does a tiny molecule help shape the future of global food security? Researchers from the University of Tasmania have provided new insights into auxin, a master plant hormone, and its vital role in ...

WEST LAFAYETTE, Ind. — Purdue University scientists Natalia Dudareva and Joseph Lynch have been searching for a way to increase a plant’s production of phenylalanine, a compound important for plant ...

A chemical dye has been discovered that reveals how a critical plant hormone helps root growth. Once we start coloring our hair, we may be surprised to learn that we begin to have a problem in common ...
