Abstract
The embryo sac of Plumbago, lacking synergids, reveals an alternative course for pollen tube growth in angiosperms and provides ultrastructural evidence for transmission of sperm cytoplasm into the zygote and endosperm. Study of such evolutionarily reduced female gametophytes may aid in elucidating the structural basis for genetic transmission of plastids and mitochondria in flowering plants.
摘要
白花丹胚囊缺乏助细胞，揭示了被子植物花粉管生长的另一种途径，并为精子细胞质进入受精卵和胚乳的传递提供了超微结构证据。对这种进化上简化的雌性配子体的研究可能有助于阐明质体和线粒体在开花植物中遗传传递的结构基础。
