中文摘要
安东诺维奇9520754 大多数植物都有雄花和雌花。 然而,有些物种在不同的植物上有雄花和雌花。 植物生态学家和遗传学家对决定这两种育种系统之间过渡的力量非常感兴趣。 拟议的研究将研究这种转变是如何在一种草本植物落新妇中表现出来的,落新妇具有中间育种系统。 了解这种转变将增加基因如何在植物中传播的知识,并将有助于为雌雄异株物种制定长期保护战略。
英文摘要
Antonovics 9520754 The majority of plant species have both male and female flowers. However, some species have male and female flowers on different plants. Plant ecologists and geneticists are keenly interested in the forces that determine the transitions between these two types of breeding systems. The proposed research will study how this transition is being manifested in an herbaceous plant, Astilbe biternata, which has an intermediate breeding system. Understanding this transition will increase knowledge of how genes can be transmitted in plants and will help to plan long-term conservation strategies for dioecious species.
