The life cycle of higher plants alternates between the diploid sporophytic and the haploid gametophytic generation. RKD transcription factors represent a novel class of gene regulators, which for instance trigger an egg cell-like transcriptome. Our current data suggest that all five members of the Arabidopsis RKD gene family are required for the control of gametophyte development. Based on three established experimental tool sets -i) a series of rkd-mutants, ii) a collection of cell-specific marker lines and iii) micro-dissected transcriptome and methylom Analysis- the project is focused on the detailed functional analysis of the RKD gene network during gametophyte development.

高等植物的生活史在二倍体孢子体和单倍体配子体世代之间交替。RKD转录因子代表了一类新的基因调节因子，其例如触发卵细胞样转录组。我们目前的数据表明，所有五个成员的拟南芥RKD基因家族所需的配子体发育的控制。基于三个已建立的实验工具集-i）一系列rkd突变体，ii）细胞特异性标记系的集合和iii）显微切割转录组和甲基化分析-该项目专注于配子体发育期间RKD基因网络的详细功能分析。
