Abstract

Maize heterochromatic knobs cheat female meiosis by forming neocentromeres that bias their segregation into the future egg cell. In this issue of , Swentowsky and colleagues (pp. 1239-1251) show that two types of knobs, those composed of 180-bp and TR1 sequences, recruit their own novel and divergent kinesin-14 family members to form neocentromeres.

摘要

玉米异染色质结通过形成新着丝粒，使它们偏向未来的卵细胞分裂，从而欺骗雌性减数分裂。在本期杂志中，Swentowsky 及其同事（第 1239-1251 页）表明，两种类型的结，由 180-bp 和 TR1 序列组成的结，招募它们自己新的和不同的驱动蛋白-14 家族成员形成新着丝粒。
