Climate change doesn’t just mean warmer weather. Cold spells can hit unusual lows, too, and the fluctuations between warm and chilly are becoming more extreme. MSU’s David Kramer is interested in resilience as it relates to photosynthesis because the process by which plants are powered by the sun is particularly sensitive to temperature swings. This knowledge could one day help certain crops grow in more places and help growers decide when to plant crops so they can harvest before the most severe stresses from heat and pests. The work of Kramer and his team was recently published online in the journal Plant, Cell & Environment.
