摘要
胚珠作为被子植物的有性生殖器官一直为植物学家所关注。19世纪以来,人们从形态结构、发生发育、起源及分子生物学等方面对胚珠进行了大量的研究。近年来,随着研究手段的不断改进,研究者对许多关键性的问题,如胚珠的起源、胚珠发生发育的分子机制已经有了一定的认识,但是这些问题并未得到圆满的解决。对此,本文对前人的研究内容进行了回顾,并综述了最新研究进展,在此基础上提出了今后对胚珠研究的建议。
As a sexual reproductive organ, ovules have received much attention by botanists. Since the nineteenth century, the morphology, structure, ontogenesis, origin and molecular biology of angiosperm ovules have been studied in detail. The development of research has resolved in part many important problems, such as the origin and molecular mechanism of ovule ontogenesis. But these problems still require further study. The present paper reviews previous research on ovules, and from a survey of the literature, suggests areas for future research on ovules.
