Abstract
Two bacterial symbionts of the European pest leafhopper, Macrosteles quadripunctulatus (Hemiptera: Cicadellidae), were fully sequenced. “Candidatus Sulcia muelleri” and “Ca. Nasuia deltocephalinicola” represent two of the smallest known bacterial genomes at 190 kb and 112 kb, respectively. Genome sequences are nearly identical to strains reported from the closely related host species, M. quadrilineatus.
Highlights
Two bacterial symbionts of the European pest leafhopper, Macrosteles quadripunctulatus (Hemiptera: Cicadellidae), were fully sequenced
Genomes were sequenced in order to characterize bacterial symbiont populations infecting M. quadripunctulatus
As observed in other leafhoppers, the average pair-wise divergence for protein-coding genes is lower between “Ca. Nasuia” PUNC and ALF strains (90.47%) than it is for the highly conserved “Ca. Sulcia” symbiont (99.68%) [24]
Summary
Two bacterial symbionts of the European pest leafhopper, Macrosteles quadripunctulatus (Hemiptera: Cicadellidae), were fully sequenced. Insects that feed on plant-sap diets (Hemiptera) rely on obligate microbial symbionts to provide essential nutrition [1]. In the Auchenorrhyncha suborder, many hosts harbor two coprimary symbionts, “Candidatus Sulcia muelleri” (Bacteroidetes) and a betaproteobacterium. These symbionts provide insect hosts with the ten essential amino acids (EAAs) [2,3,4].
