A dominant, genome-reduced symbiont of the whiteleg shrimp gastric microbiome retains an atypical peptidoglycan biosynthesis pathway: Genomic characterization of Candidatus Penaeiplasma gastricola gen. Nov., sp. nov.
A previously uncharacterized Enteroplasmatales lineage dominating the shrimp gastric microbiota and exhibiting strong signatures of reductive evolution and host adaptation is identified, providing a genomic framework for understanding the ecological roles and evolutionary history of dominant gastric symbionts in penaei...
