Plants reap energy from the sun using two photosynthesis pathways, C3 and C4. A new study led by Haoran Zhou, Erol Akçay and Brent Helliker suggests that water availability drove the expansion of C4 species, which may help to explain how different plant lineages came to be distributed on the planet today.
How plants cope with stress
How plants cope with stress
With climate change comes drought, and with drought comes higher salt concentrations in the soil. Brian Gregory and graduate student Stephen Anderson have identified a mechanism by which plants respond to salt stress, a pathway that could be targeted to engineer more adaptable crops.
