During postembryonic development plants undergo several dramatic phase changes. A good example is the switch from vegetative growth to flowering. During this event, the shoot apical meristem switches fate and starts producing flowers instead of leaves. We have studied this process on a global scale by expression profiling. We have identified a small, plant specific gene family, now called UGF, which is comprised of four members in Arabidopsis. The UGF genes are highly responsive to changes in photoperiod. We will study in detail how the UGF genes contribute to meristem identity and floral induction. To that end we will analyse the expression of the UGF genes and subcellular localization of the gene products. We will further create and analyse 'loss-of-function' and 'gain-of-function' alleles for all four UGF genes. We will also carry out a detailed analysis of the transcriptional regulation of the UGF genes. Finally, we will identify proteins that physically interact with the UGF proteins. The role of these proteins will be analysed. In the end we hope to integrate the UGF genes and interacting proteins in the network of meristem maintenance and floral transition.

在胚胎后发育过程中，植物经历了几个戏剧性的相变。一个很好的例子是从营养生长到开花的转变。在此事件期间，芽顶端分生组织改变命运并开始产生花朵而不是叶子。我们通过表达谱在全球范围内研究了这一过程。我们已经鉴定了一个小的植物特异性基因家族，现在称为 UGF，由拟南芥中的四个成员组成。 UGF 基因对光周期的变化高度敏感。我们将详细研究 UGF 基因如何促进分生组织特性和花诱导。为此，我们将分析 UGF 基因的表达和基因产物的亚细胞定位。我们将进一步创建和分析所有四个 UGF 基因的“功能丧失”和“功能获得”等位基因。我们还将对UGF基因的转录调控进行详细分析。最后，我们将鉴定与 UGF 蛋白质发生物理相互作用的蛋白质。将分析这些蛋白质的作用。最后，我们希望将 UGF 基因和相互作用蛋白整合到分生组织维持和花转变的网络中。
