Abstract excerpt
TERMINAL FLOWER2 (TFL2) is the only homolog of heterochromatin protein1 (HP1) in the Arabidopsis genome. Because proteins of the HP1 family in fission yeast and animals act as key components of gene silencing in heterochromatin by binding to histone H3 methylated on lysine 9 (K9), here we examined whether TFL2 has a similar role in Arabidopsis. Unexpectedly, genes positioned in heterochromatin were not activated...
