Sequence alignment of the seven nonrecombinant and three recombinant variants of the ECM34 promoter region found inSaccharomyces strains (see Table 1). Variable positions are shown in negative. Italic sequences in parentheses correspond to repeated regions, and subscript numbers after the parentheses indicate the number of repeats. Continuous rectangles highlight a small direct repeated sequence flanking a large 76-bp sequence repeat that could be involved in its duplication. Dotted rectangles indicate a small imperfect repeat that could be involved in the generation of a 47-bp duplication found in the CECT11032 strain. The discontinuous rectangle indicates the crossing-over site involved in the reciprocal translocation t(VIII,XVI).
