Radial growth—thickening of stems and roots driven by the vascular cambium—is essential for plant stability, transport of water and nutrients, and wood formation. Although the plant hormone cytokinin ...

Cytokinin signalling remains a central focus in plant biology due to its vital role in regulating cell division, meristem maintenance and overall plant architecture. Recent investigations have ...

Biologists have discovered how cytokinin activates stem cell division in plants. The mechanism by which the plant hormone cytokinin controls cell division has been discovered -- a breakthrough that ...

Researchers have shown how one hormone pathway in plants regulates the way leaves build their epidermal layer with the right number of breathing pores, giving plants a strategy to optimize their ...

Leaf senescence is a tightly regulated developmental process that directly affects plant productivity and lifespan.

Cytokinin receptors play a key role in cytokinin-dependent processes regulating plant growth, development, and adaptation; therefore, the functional properties of these receptors are of great ...

As the world heats up, plants face a dilemma - the same tiny holes they have to open to exchange gases also let out water. They can close the holes, called stomata, to stay hydrated in hotter, drier ...
