RT   recombination in Arabidopsis thaliana.";
RL   New Phytol. 193:364-375(2012).
CC   -!- FUNCTION: Involved in double-strand break repair and/or homologous
CC       recombination by mediating RAD51- and DMC1-facilitated DNA repair.
CC       Plays an essential role in both somatic and meiotic homologous
CC       recombination. Is crucial for the formation of RAD51 and DMC1 foci
CC       during male meiotic homologous recombination in prophase I.
CC       {ECO:0000269|PubMed:15014444, ECO:0000269|PubMed:22039535,
CC       ECO:0000269|PubMed:22077663}.
CC   -!- SUBUNIT: Interacts with RAD51 and DMC1 (PubMed:15014444,
CC       PubMed:16415210). Interacts with DSS1(I) and DSS1(V)
CC       (PubMed:16415210). Can interact with both RAD51 and DSS1(I) or
CC       both DMC1 and DSS1(I) in a tripartite complex (PubMed:16415210).

CC   -!- TISSUE SPECIFICITY: Expressed in flower buds.
CC       {ECO:0000269|PubMed:15014444}.
CC   -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC       conditions, but the double mutants brca2a and brca2b are sterile
CC       due to aberrant chromosome aggregates, chromosomal fragmentation
CC       and missegregation during meiosis. {ECO:0000269|PubMed:22039535,
