CC   -!- FUNCTION: May stabilize the accumulated carotenoid structures.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- TISSUE SPECIFICITY: Expressed almost exclusively in petals. Very weak
CC       expression in all other organs. {ECO:0000269|PubMed:11351096}.
CC   -!- INDUCTION: Down-regulated by drought and oxidative stresses. Up-
CC       regulated by wounding.
CC   -!- SIMILARITY: Belongs to the PAP/fibrillin family. {ECO:0000305}.
