Scientists know that homologous recombination repair is also required for the repair of DNA cross-links, but the exact details remain to be resolved, Chen said.

Consequence of homologous recombination, in which hybridization between different alleles causes one allele to be converted into the other. This occurs by mismatch repair.

Plant could repair DNA damage induced by UV-B through many methods, mainly included light-repair, base excision repair, nucleotide excision repair and recombination repair etc.
