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 ...

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.

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 ...

MAKING LEMONS and grapes plumper, persuading asparagus to send out more shoots, and waking up a wide variety of seeds from dormancy are all part of gibberellin's job description, but how this plant ...
