Sequences of Hebe 5' and 3' termini and internally deleted regions. (a) 5'-terminal regions from 12 sequenced copies; (b) 3'-terminal regions from 11 sequenced copies, designated as in Figure 1b. Copies represented in both a and b sets, and the corresponding target site duplications, are underlined. The CATT initiator sequence and the polyadenylation signal are italicized. (c) Comparison between the Hebe consensus sequence (Cons) and the corresponding deleted regions from copies with internal deletions shown in Figure 1b. Copies G, F, L and M share the same deletion boundaries. Four deletions in copy O (O.1, O.2, O.3, O.4, from left to right) are shown. Microhomologies are underlined.
