Contribution of the TGA/NPR network and redox-processes to the evolution of sexual reproduction

植物对陆地的殖民以及随后适应陆地生活方式的陆地植物的成功辐射是地球历史上的一件大事，可以追溯到大约500英里。由于转录因子能够同时调节许多靶基因的表达水平，因此对转录因子的贡献和功能多样性的分析是非常有意义的。这有助于了解形态和生化生殖创新的起源，这些创新能够使陆地植物及其有性繁殖过程适应于与保护的水生环境以外的新生命形式相关的新的生物和非生物挑战。氧化还原调节是一种控制转录因子在发育过程中作用的新机制，它整合了涉及活性氧的信号过程。在这里，我们旨在揭示TGA/NPR的活动以及氧化还原过程在陆地植物有性繁殖调控中的影响。为了了解转录因子/辅助调节因子网络在陆地植物日益复杂的繁殖模式形成中的贡献，我们将通过对有趣的、进化信息丰富的陆地植物进行功能和分子分析来研究它们的网络。

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.
