The genomic structure of the PgD5 gene. (A) Gene structure of PgD5. The numbering above the scheme refers to the amino acid sequence of the PgD5 precursor, and the figures below the scheme correspond to the nucleotide sequence of the PgD5 gene. (B) The complete coding sequence and the deduced amino acid sequence of PgD5 encoded within the EST GQ01307_A13. The underlined amino acids represent the signal peptide (1–27 aa) while blue amino acids indicate the mature peptide (28–77 aa). The intron (65–160 nts) is indicated by lowercase letter.
