How light and temperature work together to affect plant growth

Plants lengthen and bend to secure access to sunlight. Despite observing this phenomenon for centuries, scientists do not fully understand it. Now, scientists have discovered that two plant factors -- the protein PIF7 and the growth hormone auxin -- are the triggers that accelerate growth when plants are shaded by canopy and exposed to warm temperatures at the same time. The findings will help scientists predict how plants will respond to climate change--and increase crop productivity despite the yield-harming global temperature rise.
