Figure 5
Diagram of 5′ and 3′ chromosomal insertion of the single ATCase duplication detected in the revertants selected in a Ty1 overexpression context. The boxed arrowheads indicate Ty LTRs and the direction of Ty transcription. TyA and TyB form the Ty ORF. The symbol * has been added to sequences which are variable in length from one strain to another. Revertants 16, 72, and 74 lack the poly(A) tract. (A) In frame insertion of the ATCase duplicated region in a δ LTR Ty1. (B) Attachment of the duplicated ATCase region to a complete Ty1 element.
