Evolutionary conservation of a miniexon. A, Spliced alignment of the translated ORF (bottom lines) originating from the EST cluster shown in Figure 7 with a rice genomic clone (GenBank accession no. AP003727); the alignment was made with the GeneSeqer program (Usuka and Brendel, 2000). B, Alignment of the Arabidopsis mini-exon and its flanking introns with a homologous region of the rice genome. The mini-exon is highlighted in red characters, the intron donor sites in green, and the intron acceptor sites in blue.
