Pseudomonas infection and AtMORC family members influence chromatin accessibility in Arabidopsis
To investigate how MORC1's role in epigenetic gene silencing impacts its function in plant immunity, chromatin accessibility was compared between mock- or Pseudomonas syringae DC3000 pv. tomato (Pst)-inoculated wild type (WT) Arabidopsis and/or the atmorc1/2 double mutant. Differential DNase I hypersensitive sites (dDHSs) detected in atmorc1/2 vs WT comparisons were predominantly located in heterochromatic transposons.
