  1. The sources potentially providesssssd by Portiera have been assessed from our analyses. Most of the sources not produced by the bacterial partner are classic metabolites of eukaryotes, and the corresponding biosynthetic pathways in MetaCyc are referred. Some sources do not seem to be produced by eukaryotes, but previous works on phloemophagous insects proposed that they were acquired from the host or its diet. The same assumptions have been made in this study, and the corresponding references have been indicated in the table.
  2. Abbreviations: D-erythrose-4-phosphate (E4P); S-adenosyl methionine (SAM); 5-enolpyruvyl-shikimate-3-phosphate (5-ES-3P); N-succinyl-L,L-2,6-diaminopimelate (N-S-LL-2,6-D).
