Pectin fragments may signal plant cells to maintain a type of growth suited to darkness.

Warmth acts on a light-sensing protein similarly to the way shade does, setting off a growth spurt in plant seedlings.

See how different environmental conditions affect the activity of a molecule sensitive to both light and temperature.

To protect the global food supply, scientists want to understand—and enhance—plants’ natural resistance to pathogens.
