摘要

开花植物的成功有性繁殖取决于双重受精，在双重受精过程中，雄性花器官（花药）内产生的花粉粒将两个精子细胞输送到胚珠，深埋在子房内，从而触发胚胎和种子周围组织的发育。尽管人们对花粉和胚胎的发育给予了很大的关注，但对这些生物发育过程中围绕它们的支持组织绒毡层和胚乳的关注却很少。有趣的是，尽管它们的起源非常不同，但这些组织在功能和发育上似乎已经融合。在这里，我们将讨论这种明显的趋同及其分子和生理基础。

Functional and developmental convergence in the reproductive "nurse cells" of flowering plants.

The successful sexual reproduction of flowering plants depends upon double fertilisation, during which pollen grains, produced within the male floral organ (the anther) deliver two sperm cells to the ovule, buried deep within the ovary, triggering the development of the embryo and the surrounding tissues of the seed. Although much attention has been given to pollen and embryo development, less has been focused on the supporting tissues surrounding these organisms as they develop, the tapetum and the endosperm. Intriguingly, despite their very different origins, these tissues appear to have converged functionally and developmentally. Here we will discuss this apparent convergence and its molecular and physiological basis.
