HHMI researchers have found an enzyme involved in the production of the plant hormone auxin. Researchers have identified an enzyme involved in the production of auxin, a plant growth hormone that ...

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 ...

image: This work provides another example of how plant hormones can be used by microbes as an environmental cue, which seems to be emerging as a common strategy as scientists learn more about how ...

An international research team investigated the genetic regulation of stem cell division in plant stems. During their investigations, they revealed that the key gene coordinating stem cells, WOX4, is ...

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 ...

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 ...

Increased levels of the hormone auxin usually promote cell growth in various plant tissues. Researchers have now shown that in special areas of the seedling, increased auxin levels trigger a different ...

Researchers have long known that the plant hormone auxin, or indole-3-acetic acid, regulates a broad range of biological functions, including flowering, fruit ripening, and root elongation. But they ...

Auxin is a hormone that is essential for the development of plants as it controls a wide range of processes. Previously, it was believed that auxin's main signaling mechanism acted only by regulating ...

Plant growth depends on the integration of environmental cues and phytohormone-signaling pathways. During seedling emergence, elongation of the embryonic stem (hypocotyl) serves as a readout for light ...
