MaSat HOR structure. A: The dot plot of the MaSat array N707 (Additional file 2); a window size is 13 bp, sequence similarity is shown in gray scale. HOR units are shown as arrows with indicated length; smaller arrows indicate HOR subunits; different colors and letters indicate subunits variants. B: 2154 bp HOR unit structure; the color code for different units is shown. C: The structure of conventional MaSat 234 bp heterotetramer. D: 58 bp unit is built of 28 bp and 30 bp subunits consisting of 7-11 bp subunits; letters indicate subunits variants.
