The Double Life of a Fungus: Defends Beetle, Attacks Plant
Andy Carstens | Aug 19, 2022
Tortoise leaf beetles enjoy the protection the fungus provides from insect predators such as ants, then carry the microbe to a mutual plant host, which their fungal symbiont infects.

Climate Change Likely to Slow Plant Growth in Northern Hemisphere
Margaret Osborne | Jun 14, 2022
While the higher temperatures and CO2 levels associated with climate change currently fuel plant productivity, a study finds that changing conditions could take a toll on photosynthesis rates in regions outside the Arctic within a decade.
