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.

Auxin has long been recognized as an important phytohormone that regulates plant growth in response to diverse developmental and environmental cues 1,2. The major naturally occurring auxin, ...

How does a tiny molecule help shape the future of global food security? Researchers from the University of Tasmania have ...

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 ...

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 ...

A team of plant scientists has uncovered how a small yet powerful organ—the rootstock cotyledon—governs the success of graft ...

Scientists have uncovered how the plant hormone auxin helps roots bend and downwards towards gravity—a process called gravitropism—even after encountering obstacles in soil. Root gravitropism, which ...

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

Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be able ...

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 ...
