Hydroxyproline-rich glycoproteins (HRGPs) are a diverse family of cell wall proteins including extensins, hydroxyproline-rich lectins of the Solanaceae, and arabinogalactans. We have analyzed the structure and expression of members of a gene family that encodes HRGPs in sunflower (Helianthus annuus ). Reconstruction experiments indicated approximately seven HRGP genes in the sunflower genome. The DNA sequence of one family member, HaGX3, revealed a single open reading frame with no introns encoding a proline-rich protein 262 amino acids in length.
