The analysis of roles of DROL1 and SUDL1 in defining intron-exon junctions
We investigated how an intron with AT-AC terminal sequences is spliced using th Arabidopsis drol1 mutant and its suppressor sudl1-1. The terminal sequences of the AT-AC intron were replaced with GT-AG, GT-AC, and AT-AG and the splicing patterns were examined by PCR and sequencing. We also investigated the splicing properties of the suppressor using a recombinant gene with duplicated intron termini.
