Essential Amino Acid Enrichment and Positive Selection Highlight Endosymbiont's Role in a Global Virus-Vectoring Pest.

ABSTRACT: Host-associated microbes display remarkable convergence in genome repertoire resulting from selection to supplement missing host functions. Nutritional supplementation has been proposed in the verrucomicrobial endosymbiont Xiphinematobacter sp., which lives within a globally widespread group of plant-parasitic nematodes that vector damaging nepoviruses to plants. Only one genome sequence has been published from this symbiont, leaving unanswered questions about its diversity, host range, role, and selective pressures within its hosts. Because its hosts are exceptionally resistant to culturing, this symbiont is best studied through advanced genomic approaches. To analyze the role of Xiphinematobacter sp. in its host, sequencing was performed on nematode communities, and then ge
