New evidence suggests that the model plant Arabidopsis has two biochemically distinct pathways that produce genetic crossovers. Studies in several organisms have revealed that one kind of crossover regulation - crossover interference - is applied differently from species to species. Arabidopsis appears to use an interference system similar to that of budding yeast.
新证据表明,模式植物拟南芥有两条产生遗传交换的生化途径。对几种生物的研究表明,一种交换调控——交换干涉——在不同物种中的应用方式不同。拟南芥似乎使用了一种与芽殖酵母类似的干涉系统。
