Analysis of epigenetic chromatin modification during mitosis in rice

Published on May 29, 2018 02:49 AM

DNA methylation and histone modification are two
important types of epigenetic modification. In this study,
we analyzed the dynamic changes and chromosomal
localizations of four different epigenetic modifications, DNA
5-MeC, H3K4me3, H3K9me2, and H3S10Ph, during mitosis
in rice. The results showed that signals from DNA 5-MeC
and H3K4me3 were distributed in the heterochromatin and
euchromatin regions respectively, but no obvious signals
from H3K9me2 were detected. There were no significant
changes noticed in these three modification patterns at
different phases during mitosis. However, the H3S10Ph,
which was mainly distributed in the centromeric regions,
showed dynamic changes during mitosis that occurred
mainly at prophase and anaphase but not at interphase
and telophase.
