Scientists pinpoint mechanism for UV damage to rice plants
...that the faulty enzyme-DNA complexes might be more susceptible to heat, they tested this hypothesis with a second experiment. They showed that the enzyme from Norin 1 disassociates from DNA more readily when exposed to heat than repair enzymes from a non-UV-sensitive rice strain.
