The ocs-like elements of the bidirectional mas1'2' promoter of Agrobacterium tumefaciens, mas1' and mas2', were analyzed to elucidate their role in the expression conferred by this promoter. Tetramers of the elements were cloned upstream of the beta-glucuronidase-coding region linked to the 35S promoter deleted at -54. Transient expression assays with tobacco (Nicotiana tabacum) and potato (Solanum tuberosum) protoplasts showed that tetramers of the mas1' element had 3- to 8-fold enhancing… CONTINUE READING
