First author Onur Oztas, PhD, a postdoctoral researcher in the Sancar lab, said, «DNA damage accumulating in a plant will impair its growth and development, so boosting the excision repair system could be a good strategy for improving crop yields.»
One is that knocking out the excision repair system leads to an increase in plant genome mutations even when the plant is kept in the dark, away from UV or other forms of light.
Now scientists from the UNC School of Medicine have confirmed and clarified key molecular details of one of these repairsystems, known as nucleotide excisionrepair.
