Mutational analysis of a plant branchpoint and polypyrimidine tract required for constitutive splicing of a mini-exon.

Abstract excerpt

The branchpoint sequence and associated polypyrimidine tract are firmly established splicing signals in vertebrates. In plants, however, these signals have not been characterized in detail. The potato invertase mini-exon 2 (9 nt) requires a branchpoint sequence positioned around 50 nt upstream of the 5' splice site of the neighboring intron and a U11 element found adjacent to the branchpoint in the upstream...
