Structural organization of the hAT family of repetitive elements in the Pseudocercospora fijiensis genome that contain the histone H3-like copies. a The relative organization of terminal inverted repeats (TIR, not drawn to scale), hAT domains and histone H3-like domains in a representative hAT element. Each element had one to two copies of the H3-like sequence, indicated by the blue boxes. The hAT element contains the DUF659 domain, shown by a solid orange box, which is found in hAT transposases but the ‘dimer_Tnp_hAT’ domain, shown by an orange box with upward diagonal stripes, could not be identified. The ruler on the top shows the length of the full-length element. b A 20-bp terminal inverted repeat (TIR) at the end of each complete element was flanked by an 8-bp target site duplication (TSD) in the host DNA. These consensus sequences were derived from 99 full-length hAT elements that met four criteria: element length of ~ 9.5 kb; presence of hAT domain; intact TIRs; and identical or nearly identical TSDs. Two positions within the TIRs showed the T to C and G to A transitions (indicated by an asterisk) that are characteristic of RIP
