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 ...

Auxin, a pivotal plant hormone, orchestrates a wide range of developmental processes including cell division, elongation, organ formation and responses to environmental stimuli. Its signalling ...

Journal of Experimental Botany, Vol. 69, No. 2, Special Issue: Recent Advances in Auxin Biology (2018), pp. 201-212 (12 pages) Being sessile organisms, plants have evolved mechanisms allowing them to ...

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 ...

Auxin is the first plant hormone—or "phytohormone"—ever identified, with its discovery dating to the late 19 th and early 20 th centuries. With its discovery, scientists began to understand how small, ...

A research team from Korea have uncovered how plants rapidly activate a hidden genetic "switch" helping them survive in cold environments. They demonstrate that low temperatures induce a rewiring of a ...

Plants have a remarkable capacity to adjust their growth and development to elevated ambient temperatures. Increased elongation growth of roots, hypocotyls, and petioles in warm temperatures are ...

Researchers from the Disruptive & Sustainable Technologies for Agricultural Precision (DiSTAP) Interdisciplinary Research Group (IRG) of Singapore-MIT Alliance for Research and Technology (SMART), MIT ...

Scientists have, for the first time, observed one of the natural mechanisms underlying the regulation of the levels of growth inhibiting hormone in plants. This mechanism had been hitherto seen in ...

The onset of sudden cold spells can threaten plant survival, especially during early growth phases. But how do plants detect ...
