Study Reveals Dynamics of Meiotic Recombination in Plants with Repeat-Based Holocentromeres

A recent study in Nature Plants explores the dynamics of crossover patterning in plants with repeat-based holocentromeres, focusing on the holocentric plant Rhynchospora breviuscula. The study reveals a distally biased crossover frequency, highlighting the primary influence of mechanistic features of meiotic pairing and synapsis rather than (epi)genomic features and centromere organization in determining the crossover distribution in this plant species.
