题目:Transcriptional Circuits, Cell Growth Dynamics and Shoot Meristem Development

报告人:周云(Zhou Yun)

告时间:2021.11.10,上午9点

地点:腾讯会议106 636 070

The research interest of Dr. Zhou’s group is to understand cellular and molecular mechanisms in control of shoot development and stem cell homeostasis, using both experimental and computational approaches. Our research centers on the stem-cell identity and function in the meristems of Arabidopsis and Ceratopteris, and we are interested in understanding: how stem cells are dynamically organized and maintained through continuous cell division, growth and differentiation; how developmental decisions are made during cell patterning and new organ formation; and how the regulatory circuits of transcription factors and microRNAs mediate cell fate specification and cell-cell communication. We are tackling these questions using multiple interdisciplinary methods, including confocal live cell imaging, computational quantification, modeling, biochemistry, molecular genetics, and functional genomics.
