During meiosis, the stepwise release of sister chromatid cohesion is crucial for the equal distribution of genetic material to daughter cells, enabling generation of fertile gametophytes. However, the molecular mechanism that protects centromeric cohesion from release at meiosis I is unclear in Arabidopsis (Arabidopsis thaliana). Here, we report that the protein phosphatase 2A regulatory subunits B'α and B'β participate in the control of sister chromatid separation. The double mutant b… CONTINUE READING
