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 ...

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 ...

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 ...

Plants use ubiquitin ligases to translate the presence of a phytohormone into a transcriptional response. Using cryo-EM, Vancea et al. reveal the mechanism underlying the perception of strigolactones ...

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, ...

Increased levels of the hormone auxin usually promote cell growth in various plant tissues. Chinese scientists together with researchers from the Institute of Science and Technology Austria (IST ...

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 ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

Summary Foliar shade triggers rapid growth of specific structures that facilitate access of the plant to direct sunlight. In leaves of many plant species, this growth response is complex because, ...

There is a mix of perennials and shrubs that should not be pruned before winter. Keep in mind that any pruning on a plant encourages growth. Pruning stimulates a growth hormone called an auxin. If ...

New tech lets scientists study plant cells without rigid walls, using tiny droplets as growth chambers. This boosts control & speed, revealing how hormones impact cell growth & survival, aiding plant ...
