Within the Lachninae subfamily of aphids, a putative ancient pseudogenisation of the riboflavin biosynthetic genes in the Lachninae's Buchnera last common ancestor rendered Buchnera unable to supply this essential nutrient to the aphid, and thus triggered the establishment of secondary co-obligate endosymbionts. Through co-occurrence data of same-haplotype secondary endosymbionts across different populations, we determined that Cinara (Cinara) watanabei apparently harbours a Serratia symbiotica symbiont as Buchnera's co-obligate endosymbiont. This population was also found to be infected by a facultative Hamiltonella defensa symbiont and its associated APSE phage.
