花粉败育型细胞质雄性不育玉米 (Zea mays):一种可能的机制。

Abstract

A rapid replication of mitochondria (20- to 40-fold increase) occurs between the precallose and tetrad stages in the tapetum of N and T corn (Zea mays) anthers, followed by mitochondrial, tapetal, and pollen breakdown in T anthers. It is suggested that the altered DNA in T mitochondria may malfunction under these stress conditions.

摘要

在 N 和 T 型玉米(玉米)花粉囊绒毡层中,在预减数分裂和四分体阶段之间,线粒体(增加 20-40 倍)快速复制,随后 T 型花粉囊的线粒体、绒毡层和花粉解体。有人认为,T 型线粒体中改变的 DNA 在这些应激条件下可能无法正常工作。
