Review: Shuffling genes for better breeds
Plant Science Research WeeklyDuring meiosis, the cell division process that generates four distinct gametes, chromosomes exchange genetic material during homologous recombination. Homologous recombination is a complex process that is tightly controlled in location and frequency – each chromosome must have at least one crossover…
Phase separation determining meiotic interference-sensitive meiotic crossover formation
Plant Science Research WeeklyIn sexual reproduction, meiosis creates new combinations between homologs and diversifies the genetic information among gametes and progenies. Most meiotic crossovers (COs) are mediated by a group of ZMM factors, including HUMAN ENHANCER of INVASION-10 (HEI10), which is suggested to concentrate at CO…
