Figure 4.

Five different refinement events which may be suggested by intragenic peptides. Exons are shown in black boxes while novel coding regions suggested by the peptides are shown in green. Peptides (dark blue and cyan) are shown aligned to the gene models. Examples drawn of refined genes in TAIR7 from Castellana et al. [37] are annotated with the updated gene model. Several of these genes have been updated in subsequent gene annotation releases to include the peptide evidence.
