Rosaceae and vaccinium floral evolution

植物进化的研究对于假设古代植物的变化是必不可少的，这些变化导致了我们今天看到的植物和花卉形式的多样性。目前，许多技术可供对花的进化感兴趣的研究人员使用。第一种是系谱学，或者说系谱学的分类，它为描述植物类群之间的关系提供了一个框架。我的研究旨在通过对两组经济和生态上重要的植物的DNA序列和花发育数据的比较分析来构建植物遗传学。 玫瑰属于一组植物，包括potentillas，乌藨子，草莓和许多生态上重要的植物。DNA分析的系统发育树表明，并非所有的成员都彼此密切相关。我的研究将使用比较花发育数据来确定这一组成员之间的不同特征，以更好地理解这些关系。这些研究结果将为花器官特征基因的进化研究提供基础。 蓝莓属于一组植物，还包括小红莓，越橘和越橘。以前的分析蓝莓的基因组使用单一的数据来源，或没有完全澄清这组内的关系。因此，我将收集数据以完成一个大型的多基因DNA数据集，以完善我们对这些植物之间关系的理解。我还将对这组花的发育进行比较分析，以调查我们在它们的花中看到的广泛变化的基础。 深入研究植物类群之间的关系，不仅可以使我们深入了解它们的进化，而且还可以提供有关具有社会经济重要性的性状的信息。从我的研究中获得的信息有可能通过帮助理解发育过程的遗传控制来帮助育种计划，以及确定可能用于育种的野生亲属的特征。这些信息也可以用于确定野生种群的保护策略。

The study of plant evolution is essential to hypothesizing the changes in ancient plants that led to the diversity of plant and flower forms we see today. Currently, a number of techniques are available to researchers interested in flower evolution. The first, phylogeny, or genealogical decent, is essential for providing a framework for representing relationships amongst groups of plants. My research seeks to construct phylogenies from comparative analyses of DNA sequences and floral development data from two economically and ecologically important groups of plants.     Roses belong to a group of plants that includes potentillas, raspberries, strawberries, and many ecologically important plants. Phylogenetic trees from analyses of DNA demonstrate that not all members of this group are closely related to one another. My research will use comparative floral development data to determine characters that differ among members of this group to better understand these relationships. Results from these studies will provide a basis for studying the evolution of floral organ identity genes.     Blueberries belong to a group of plants that also includes cranberries, bilberries, and partridge berries. Previous analyses blueberry of phylogeny use single sources of data, or do not fully clarify relationships within this group. Therefore, I will collect data to complete a large, multi-gene DNA data set to refine our understanding of relationships amongst these plants. I will also carry out comparative analyses of flower development of this group to investigate the basis for the wide variation we see in their flowers.     Thorough investigations of the relationships amongst plant groups not only provide us with insight into their evolution, but also provide information concerning characters with socio-economic importance. Information from my research has the potential to assist breeding programs by helping understand the genetic control of developmental processes, as well as determining characteristics in wild relatives that may be of use in breeding. This information can also be employed in determining strategies for the conservation of wild populations.
