Figure 5.
Characteristics of TEs containing three or more TFBMs/TFBS present at (A) high frequency or (B) fixed (non-INE-1). Histone mod: TE bears H3K4me3 or H3K36me3 marks associated with active chromatin. Open chromatin: TE is located in an open chromatin region. Evidence of selection: TEs with evidence of selection (41). Reg. region: TE is located in the proximal regulatory region of a gene (promoter, 5′UTR or first intron). Gene association: TEs located nearby stress-associated genes. Ratio TFBS: TE contains 20% more TFBS than expected given their length.
