Two complete operons encoding cytochrome bo3-type ubiquinol terminal oxidases (cyoABCD-1 and cyoABCD-2) were found in most Asaia genomes, possibly offering alternative terminal oxidases and allowing the flexible transition of respiratory pathways. Genes involved in the production of 2,3-butandiol and inositol have been found in Asaia sp. W12, possibly contributing to biofilm formation and stress tolerance.

infected WBPH were of shorter nymphal duration and heavier adult weight. Asaia sp. plays a role in improving WBPH fitness through involvement in host’s nutrient supply

Asaia plays a role in improving the white-backed planthopper (WBPH) fitness through involvement in host’s nutrient supply

Asaia sp. strain effectively lodged in the female gut and salivary glands, sites that are crucial for Plasmodium sp. development and transmission
