RT Journal Article SR Electronic T1 Cooperative Interactions Between Pairs of Homologous Chromatids During Meiosis in Saccharomyces cerevisiae JF Genetics JO Genetics FD Genetics Society of America SP 1125 OP 1127 DO 10.1534/genetics.108.088567 VO 179 IS 2 A1 Mell, Joshua Chang A1 Komachi, Kelly A1 Hughes, Owen A1 Burgess, Sean YR 2008 UL http://www.genetics.org/content/179/2/1125.abstract AB We report a novel instance of negative interference during Saccharomyces cerevisiae meiosis, where Cre-mediated recombination between pairs of allelic loxP sites is more frequent than expected. We suggest that endogenous crossover recombination mediates cooperative pairing interactions between all four chromatids of a meiotic bivalent.
