Unleashing meiotic crossovers in hybrid plants ($) (PNAS)
Plant Science Research WeeklyTo generate new plant varieties with desirable traits, plant geneticists cross existing varieties that contain the characters they want to combine. The genetic variability is obtained thanks to events called crossovers, in which segments of homologous chromosomes are swapped during meiosis. The frequency…

Hold Me Closer: Meiotic Crossover Formation and FANCD2
Blog, The Plant Cell, The Plant Cell: In BriefMeiosis takes a single, diploid cell and turns it into four haploid spores. The equal distribution of genetic material is critical for genome stability across generations, and relies heavily on proper pairing of chromosomes and their timely release. During the first meiotic division, crossovers (COs)…
