Phylogenetics an morphological diversification in capparaceae, cleomaceae, and brassicaceae

尽管我们对在开花植物中观察到的形式多样性很着迷，但我们对这种变异是如何产生的理解是有限的。 我的研究目标是更好地了解两个关键性状差异的机制：果实结构和花的对称性。 芥菜科中的一个组，称为芥菜科，是重要的，因为它包括作物物种（例如油菜，西兰花），因为水果通常是分段的，这一特征极大地改变了它们的种子是如何传播的。 随着转基因作物系统中种子传播和基因流控制的日益重要，以及自然生态系统中引入物种的日益普遍，有必要详细了解果实发育遗传学和进化。 在刺山柑科的物种揭示了一个令人印象深刻的变化，在花的形式，包括许多变化，花的对称性。 这一特性对传粉者的相互作用，包括促进物种形成和多样化有着重要的影响。

Despite our fascination with the diversity of forms observed in flowering plants, our understanding of how this variation has arisen is limited. The goal of my research is to better understand the mechanisms underlying differences in two key traits: fruit structure and floral symmetry. A group within the mustard family, called the Brassiceae, is important because it includes crop species (e.g. canola, broccoli) and because the fruits are often segmented, a trait that dramatically alters how their seeds are dispersed. The increasing importance of seed dispersal in crop plants and controlling the gene flow in genetically modified crop systems, and the increasing prevalence of introduced species in natural ecosystems, necessitate a detailed knowledge of fruit developmental genetics and evolution. Species in the caper family reveal an impressive variation in floral form, including many changes in floral symmetry. This trait has a significant impact on pollinator interactions including promoting speciation and diversification.
