The RAD51 paralogue HvXRCC2 affects meiosis and recombination in barley.

Abstract excerpt

Using a positional candidate-gene approach, we show that semi-sterile desynaptic8 mutants are associated with deleterious variants of the barley homolog of XRCC2 (X-Ray Repair Cross Complementing 2). In barley XRCC2 mutants, the initial meiotic progression is normal, albeit with a small delay in initiation, with completion of synapsis. However, the absence of HvXRCC2 subsequently leads to a dramatic reduction in...
