ABSTRACT
The genomes of obligate bacterial co-symbionts of the green rice leafhopper
Nephotettix cincticeps
, which is notorious as an agricultural pest, were determined. The streamlined genomes of “
Candidatus
Sulcia muelleri” and “
Candidatus
Nasuia deltocephalinicola” exhibited complementary metabolic pathways for synthesizing essential nutrients that contribute to host adaptation.
