Gene expression of an arabinogalactan lysine-rich protein CaAGP18 during vegetative and reproductive development of bell pepper (Capsicum annuum L.).

ABSTRACT: Lysine-rich (Lys-rich) proteins encoded by AGP17, AGP18, and AGP19 genes are cell wall-associated glycopeptides related to sexual reproduction in flowering plants. This subclass belongs to classical arabinogalactan proteins (AGPs) widely studied in model plants like Arabidopsis. In this study, we identified the CaAGP18 cDNA from bell pepper (Capsicum annuum L.), as well as its expression pattern during vegetative and reproductive development. The deduced amino acid sequence revealed a Lys-rich AGP18 protein of 238 amino acids residues in length with an estimated molecular mass of 22.85 kDa and an isoelectric point of 9.7. The protein is predicted as canonical AGP due to the presence of a small Lys-rich region and a C-terminal sequence essential for posttranslational modification with a gly
