Diversity in somatic DNA repair efficiencies between commercial inbred maize lines and native Central American purple landraces
(2021)
Maize is a staple food all over the world. Models for climate change suggest that, in the future, cloud formation might be reduced in the tropics increasing the exposure to Ultraviolet-B (UV-B) radiation, a DNA-damaging ...
Diversity in mitotic DNA repair efficiencies between commercial inbred maize lines and native Central American purple landraces
(2022-10)
Background: Homologous recombination allows plants to repair double strand breaks in DNA, which if unrepaired
may lead to cell death. In this project, we determined the relative DNA repair efciency of the US inbred lines ...
