Temporal and spatial expression analysis of PRGL in Gerbera hybrida.

GASA-like genes form multigene families in diverse plant species and encode the proteins with a unique cysteine-rich domain (GASA domain). In our previously work, we cloned a GASA-like gene PRGL (Proline-rich GASA-like) from gerbera. Here we report the expression profiles of PRGL and the subcellular localization of PRGL protein.

PRGL: A cell wall proline-rich protein containning GASA domain in Gerbera hybrida.

PRPs (proline-rich proteins) are a group of cell wall proteins characterized by their proline and hydroproline-rich repetitive peptides. The expression of PRPs in plants is stimulated by wounding and environmental stress. GASA (gibberellic acid stimulated in Arabidopsis) proteins are small peptides sharing a 60 amino acid conserved C-terminal domain containing twelve invariant cysteine residues.
