  • Whole-system view of plant cold stress
    on October 29, 2018 at 5:09 pm

Scientists have described these changes and identified some of the genes controlling them, but it's not clear how all the processes work together. Lacking this global view, plant breeders have struggled to engineer cold-tolerant crops. A recent study provides answers. […]
