What happens when trees lose the ability to cool their leaves? 🌳 Although trees can acclimate to heat, drought disrupts thermoregulation, driving a hydraulic–thermal cascade and leaf scorching. 🍂 Just out in PNAS doi.org/10.1073/pnas...

As the world warms, plants in natural ecosystems and agricultural settings find ways to respond to the heat. In a new special issue of Science, researchers examine how heat affects plants at multiple scales, from the molecular level to the biosphere. scim.ag/44cSw3Z

Infrared imaging shows heat levels in sun-exposed leaves of Alstonia scholaris from the Australian Wet Tropics. As climate change increases temperatures and the severity of heat waves, both natural ecosystems and agricultural plants are increasingly affected by heat. Examining heat responses at cellular, genetic, physiological, and ecosystem scales, this special issue explores how plants sense and respond to high temperatures.
