Figure 4

Predicted gene structure patterns for putative rice GH1 β-glucosidase genes. Exons are shown as boxes with corresponding exons having the same pattern. Introns, represented as simple lines, are drawn in proportion to their length. Note that 5 gene organization patterns can be seen in rice genes, those with 13, 12, 11, or 9 exons and intronless patterns, with the splice sites conserved in each group and between groups for common exons and introns.
