Plants feel the heat: How a protein 'thermometer' helps plants adapt to climate

Plants continuously adapt to environmental changes, and temperature is a key signal for growth and flowering. How plant thermometers, or "thermosensors," work at the molecular level is not well understood.

Knowing how plants stretch out when warm could help dial back their response

When they start to get too warm but before they're dangerously hot, most plants employ a similar playbook. They change their shape, a host of adaptations that includes growing longer stems and stalks to promote air circulation.
