DESCRIPTION:Speaker: Yoko Ikeda\nhosted by Xiaoqi Feng\nAbstract: Among epi
 genetic regulatory mechanisms\, both DNA methylation and histone modificat
 ions are known to be inherited through cell division. However\, in plants\
 , (CG) DNA methylation is generally maintained more stably across generati
 ons\, whereas histone modifications are often reset during gametogenesis a
 nd early embryogenesis. I am interested in the regulatory machinery underl
 ying these two epigenetic layers and have been investigating their dynamic
 s using Arabidopsis\, Marchantia\, and barley. In this presentation\, I wi
 ll introduce our recent work on the control of 5-methylcytosine during dif
 ferent life stages of Marchantia\, in which we are analyzing mutants of DN
 A methyltransferase and DNA demethylase to dissect the regulatory mechanis
 ms involved. In addition\, we have uncovered a novel histone-modification 
 mediated pathway involving barley EMF1 that regulates awn elongation\, and
  we are currently exploring its detailed molecular mechanisms. These findi
 ngs provide new insights into how distinct epigenetic systems operate and 
 have developed in plants.
