Plants integrate different regulatory signals to control their growth and development. Although a number of physiological observations suggest that there is crosstalk between the phytohormone ...

Rumex palustris responds to complete submergence with upward movement of the younger petioles. This so-called hyponastic response, in combination with stimulated petiole elongation, brings the leaf ...

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.

As published in the December 1st issue of Genes & Development, Dr. Nam-Hai Chua and his team at Rockefeller University in New York have begun to unravel the molecular mechanisms by which plants ...

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 ...

Phytohormones affect differentiation and growth of plant cells causing permanent, irreversible changes in the activities of cells. In contrast to animals — where a hormone often acts quite ...

A target of the plant hormones known as gibberellins has been identified. Gibberellins induce many well-characterized responses in plants, including stem elongation, but how they do so is not known.

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 ...

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 ...
