When cells sense the cue for growth

Researchers of the Genome Dynamics Project team at Tokyo Metropolitan Institute of Medical Science have revealed a new mechanism controlling cellular proliferation in response to serum, which triggers growth of resting cells.

How do plants know how big to grow?

Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms ...

The mechanisms that produce 'menopause' in plants identified

In those plants with a single reproductive episode, called monocarpics, the onset of reproduction is marked by the formation of the first flowers. The signals that control the start of flowering are highly studied (light, ...

Planting a new perspective on climate research

(Phys.org) —A study on the mechanisms of how plants respond and adapt to elevated levels of carbon dioxide (CO2) and higher temperatures has opened a new perspective in climate research. Lead researcher Qiong A. Liu (Alison) ...

DNA damage: The dark side of respiration

(Phys.org) —Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at LMU now report how byproducts of respiration cause mispairing ...
