The colonization of the land by plants and the subsequent successful radiation of land plants adapted to a terrestrial life style is a major event in Earth history and dates back around 500 MYs. The analysis of the contribution and functional diversification of transcription factors (TFs), given their capacity to regulate the expression levels of numerous target genes in parallel, is of prime interest. This allows to understand the origin of morphological and biochemical reproductive innovations that were able to adapt land plants and their sexual reproduction processes to the exposure of novel biotic and abiotic challenges associated with a new life form outside a protective aquatic environment. Redox-regulation, integrating signaling processes involving reactive oxygen species (ROS), is emerging as a novel mechanism controlling TF functions in developmental processes. Here, we aim to unravel TGA/NPR activities and the impact of redox-processes in the regulation of sexual reproduction in land plants. To understand the contribution of the TF/coregulator network to the formation of increasingly complex reproduction modes of land plants, their networks will be investigated by functional and molecular analyses in interesting, evolutionary informative land plants.

植物在陆地上的殖民化以及随后成功地辐射陆地植物适应陆地生活方式是地球历史上的一个重大事件，可以追溯到大约500 MYs。转录因子（TF）的贡献和功能多样性的分析，考虑到他们的能力，调节许多靶基因的表达水平平行，是最感兴趣的。这使我们能够了解形态学和生物化学生殖创新的起源，这些创新能够使陆地植物及其有性生殖过程适应与保护性水生环境之外的新生命形式相关的新生物和非生物挑战。氧化还原调节是一种新的调控TF功能的机制，它整合了活性氧（ROS）的信号传导过程。在这里，我们的目标是解开TGA/NPR活动和氧化还原过程的影响，在陆地植物有性生殖的调节。为了了解TF/coregulator网络的贡献，形成越来越复杂的陆地植物的繁殖模式，他们的网络将调查有趣的，进化信息陆地植物的功能和分子分析。
