合子后屏障的渗透性:部分可育的表皮牡丹(兰科)杂交种的胚胎学。
杂交区为了解繁殖障碍和植物物种形成机制提供了独特的视角。本研究调查了天然杂交植物Epidendrum × purpureum的杂交后代生殖隔离情况。我们研究了该杂交区雌雄配子体的发育以及种子形成的过程。我们采集了E. × purpureum个体在不同发育阶段的花蕾和花朵。进行了自花授粉和杂交种与亲本之间的回交,以跟踪授粉后 60 天内胚珠和种子的发育情况。使用光学显微镜和共聚焦显微镜对材料进行分析。在大多数杂交种中,小孢子发生和小配子发生都是有规律的,会形成有活力的雄配子体。也观察到了不能存活的雄配子体,它们是对称有丝分裂的结果。雌配子体的发育发生在自花授粉之后,并有规律地进行,最终形成退化的雌配子体。亲本的胚胎发育没有异常,而在杂交种和亲本之间的回交中,大多数胚胎都会退化。杂交种之间杂交的胚胎退化可以用基因不相容来解释。在杂交种与亲本之间的回交中,有活力的胚胎和退化的胚胎同时出现,这表明杂交种与亲本之间的后代生殖屏障不完整。我们的研究结果表明,E. × purpureum 可以促进亲本物种之间的基因流动,因为它的大部分胚胎发育过程都没有异常。

期刊介绍: Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
