All flowering plants have carpels, female reproductive structures that enclose the eggs and subsequently develop into seedpods and fruits. Carpel development genes are being defined in the model species Arabidopsis, an advanced flowering plant. But the evolutionary origin of carpels is not clear. In this project, we will identify and characterize genes that control carpel development in a more primitive plant, California poppy (Eschscholzia californica). This new model species is a basal eudicot that can be manipulated transgenically. Comparison of carpel genes in poppy and Arabidopsis will help reveal core genes that underlie carpel development in all flowering plants. This will allow us to identify genes that play the same important role in carpel development across dicots, and also those that play more specialized roles. The underlying question is how gene networks, consisting of developmental genes from different gene families, govern plant development and how these networks evolve resulting in changes to plant structure.

所有开花植物都有心皮，这是一种雌性生殖结构，它包裹着卵，随后发育成豆荚和果实。心皮发育基因正在模式物种拟南芥（Arabidopsis）中定义，拟南芥是一种高级开花植物。但心皮的进化起源尚不清楚。在这个项目中，我们将确定和表征基因，控制心皮发育在一个更原始的植物，加州罂粟（scholzia californica）。这个新的模式物种是一个基础真双子叶植物，可以转基因操纵。比较罂粟和拟南芥心皮基因有助于揭示所有开花植物心皮发育的核心基因。这将使我们能够确定在双子叶植物心皮发育中发挥同样重要作用的基因，以及那些发挥更专门作用的基因。潜在的问题是，由来自不同基因家族的发育基因组成的基因网络如何支配植物的发育，以及这些网络如何演变导致植物结构的变化。
