Figure 2

Exon-intron structures of the seventeen PR10 related sequences. A: length of exons (bold dashes) and introns (thin dashes). B: frequency of nucleotides at the 5' and 3' putative splicing sites of introns. The size of letters is proportional to the nucleotide frequency at each position. The numbers indicate nucleotide position relatively to the first nucleotide of intron 1 (number 1 at the 5' end) or to the first nucleotide of exon 2 (number 1 at the 3' end). VvPR10.1, VvPR10.2 and VvPR10.3 respectively correspond to s16, s10 and s12.
