Role of RAD51 in the repair of MuDR-induced double-strand breaks in maize (Zea mays L.).

Abstract excerpt

Rates of Mu transposon insertions and excisions are both high in late somatic cells of maize. In contrast, although high rates of insertions are observed in germinal cells, germinal excisions are recovered only rarely. Plants doubly homozygous for deletion alleles of rad51A1 and rad51A2 do not encode functional RAD51 protein (RAD51-). Approximately 1% of the gametes from RAD51+ plants that carry the...
