NSF Award Boosts Research into Freeze-Tolerant Crops

March 8, 2019

For some plants — like corn — below-zero temperatures trigger a cascade of lethal damage. For others, the damage isn't permanent. UNL biochemist Rebecca Roston is working to identify key properties so one day more freeze-tolerant crops might be developed.
