The repertoire of Carsonella and Profftella genes that are potentially involved in providing nutrition. (A) Amino acid and vitamin biosynthetic genes in the genomes of Carsonella and Profftella from Diaphorina cf. continua and Diaphorina citri. Filled and open boxes indicate the presence and absence of genes, respectively. (B) B vitamin synthetic pathways reconstructed from genes retained in the genomes of Profftella_Dco and Profftella_DC. Genes shown in black type are found in the Profftella genomes. Those in gray type appear to be absent in the genomes. The ribC shown in green type is a host psyllid gene that was horizontally acquired from an unknown bacterium.
