报告内容：

In higher plants, after fertilization complex combinations and interactions of maternal and paternal genomes occur, and thus, it is critical point for understanding the molecular mechanism underlying zygote development and embryogenesis initiation. In animals, it is clear that zygote development and early embryogenesis are maternally controlled, and zygotic genome activation (ZGA) occurs after several rounds of embryonic cell division. However, in flowering plants, although great efforts have been made in recent decades several major questions are still waiting to be answered. Firstly, it is unclear if the MZT has two conserved processes in plants or if plant MZT possesses a unique character with only ZGA process. Secondly, our knowledge on parental contributions to the zygotic genome is still confusing due to contradictory results from different reports. Thirdly, we think that it is necessary to test if the de novo transcripts are indeed involved in the zygote development and early embryogenesis. In this talk, we will address above mentioned questions and discuss mainly paternal roles in early embryogenesis.
