ROW: Resource Allocation Patterns in Dimorphic Plants

生物体将资源分配给各种活动， 例如繁殖、生长和维持， 一般认为，分配资源给任何一个 一项活动是以牺牲其他活动为代价的。 植物 提供了一个很好的机会，以确定如何资源 分配策略受个体性别的影响， 因为许多属都包含性别表达不同的物种。 在蝇子草属中，有一些物种 雌雄同体（一个个体中的两性）和其他 雌雄异株（单独的雄性和雌性个体）。 它已被证明是雌雄异株的一种蝇子草 男性和女性在资源分配上 模式. Delph博士的长期研究计划包括 研究这些差异是如何演变的。 为此， 有必要明确地确定植物的性别 在其发展的早期。 目前，一个人的性别 只有在开花时才能确定个体。 的 赠款将提供必要的资金，以发展分子 技术，使性别决定之前， 开花 此外，还将制定一项技术方案， 用来检测性别之间的差异 开花和结果的资源源自植物内部。

Organisms allocate resources to a variety of activities, such as reproduction, growth, and maintenance, and it is generally perceived that the allocation of resources to any one activity occurs at the expense of the other activities. Plants provide an excellent opportunity to determine how resource allocation strategies are affected by the sex of an individual, as many genera contain species that vary in their sex expression. Within the genus Silene, there are species that are hermaphroditic (both sexes in one individual) and others that are dioecious (separate male and female individuals). It has been shown for one of the dioecious species of Silene that males and females have very different resource allocation patterns. Dr. Delph's long-term research plans include investigating how these differences evolved. In order to do so, it is necessary to unambiguously determine the sex of plants early in their development. At the present time, the sex of an individual can only be determined when it is flowering. The grant will provide necessary funds to develop molecular techniques that would enable sex determination prior to flowering. In addition, a protocol for a technique will be developed to detect differences between the sexes in where resources for flowering and fruiting originate within the plant.
