Sensing of the plant hormone auxin involves formation of a co-receptor complex consisting of an F-box protein and an AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) transcriptional repressor. Distinct ...

The plant growth regulator auxin controls cell identity, cell division and cell expansion. Auxin efflux facilitators (PINs) are associated with auxin maxima in distal regions of both shoots and roots.

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.

Root hairs represent a low-cost strategy to enhance nutrient uptake because they can significantly increase the nutrient-acquiring surface of plant roots. While primary and lateral roots are ...

During the development of organisms, a particular event repeatedly occurs: a signal appears temporarily, but the processes it triggers must be maintained -- for example, when the fate of cells in the ...

Multiple gibberellins (GAs) were quantified in the stems of intact, decapitated, and decapitated auxin-treated barley (Hordeum vulgare) plants. Removal of the developing inflorescence reduced the ...

• Background The phytohormone auxin is critical for plant growth and orchestrates many developmental processes. • Scope This review considers the complex array of mechanisms plants use to control ...

Grape berry softening is a crucial physiological transition that affects postharvest storage, transport, and flavor. During ripening, the cell wall components—pectin, cellulose, and ...

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 ...

Researchers have found a way to control protein levels inside different tissues of a whole, living animal for the first time.

Grape berry softening is a crucial physiological transition that affects postharvest storage, transport, and flavor. During ripening, the cell wall components-pectin, cellulose, and ...

Part of Biology (Single Science) Using food and controlling growth When the stem grows against the force of gravity (upwards), this is known as a negative gravitropism. When a root grows in the ...
