a A proposed model for l-ascorbic acid biosynthesis pathways in star fruit. Genes identified as being involved in the pathways are shown in blue circles. b Phylogenetic analysis of the GalDH gene family in A. carambola (rose red), A. thaliana (purple), C. sinensis (yellow), C. papaya (blue), P. trichocarpa (sky blue), S. lycopersicum (orange), and V. vinifera (green).
