Abstract excerpt

The maize polyubiquitin-1 (Ubi-1) promoter is one of a few select promoters used to express foreign genes in monocots, such that recombinant proteins can be produced at commercially viable levels. Modifying the activity, specificity and responsiveness of such promoters provides a means to achieve desired levels and patterns of expression of genes encoding target products. Ubi-1 is constitutively expressed but is...
