Genetic and molecular analysis of trichome and root hair development in Arabis alpina

研究进化机制的一种可能是比较密切相关物种之间明显同源的过程。在此，我们建议建立毛状体和根毛发育的遗传和分子模型系统，以便与拟南芥进行比较。我们已经完成了毛状体突变体的基因筛选，并将在2012年底完成根毛筛选。我们建议对突变体进行表型表征，以便更好地分类，进行互补测试，并对突变体中的候选基因进行测序，以确定相应的基因。本项目部分的目的是通过功能鉴定参与毛和根毛发育的大部分基因。第二个项目旨在更详细地描述一个关键基因TTG1，它与毛状体、根毛发育、花青素、原花青素和种皮粘液的产生有关。

One possibility to study evolutionary mechanisms is to compare clearly homologous processes between closely related species. Here we propose to establish trichome and root hair development as genetic and molecular model systems in A. alpina to enable a comparison with A. thaliana. We have finished the genetic screen for trichome mutants and will finish the root hairs screen by the end of 2012. We propose to phenotypically characterise the mutants for a better classification, to perform complementation tests, and to sequence candidate genes in the mutants to identify the corresponding genes. The aim of this project part is to identify most genes involved in trichome and root hair development by its function. A second project aims to characterise one key gene, TTG1, that is involved in trichome, root hair development, anthocyanidin, proanthocyanidin and seed coat mucilage production in more detail.
