Analysis of H3K9me2 and H3K9me3 levels within regions flanking dispersed polymorphic TCAST1 elements.
Level of H3K9me2 and H3K9me3 within region proximal to: a) element 46 in strain GA2 (blue) and within the same region in strain 43 (red) without element 46, b) element 21 in strain GA2 (blue) and within the same region in strain 61 (red) without element 21, c) element 2 in strain GA2 (blue) with element 2 in the form of trimer and within the same region in strain 43 (red) with element 2 as a monomer. H3K9me2/3 levels were measured by ChIP at standard conditions (no HS) and at 45 min and 1.5 hours of recovery period after long-term heat stress. Data show average of three independent replicate experiments and error bars indicate the standard error.
