Phylogenomics Reveals Clear Cases of Misclassification and Genus-Wide Phylogenetic Markers for Acinetobacter
GBE Phylogenomics Reveals Clear Cases of Misclassification and Genus-Wide Phylogenetic Markers for Acinetobacter Valeria Mateo-Estrada, Lucıa Grana-Miraglia*,~ Gamaliel Lopez-Leal, and Santiago Castillo-Ramırez* Programa de Genomica Evolutiva, Centro de Ciencias Genomicas, Universidad Nacional Autonoma de Mexico, Cuernavaca, Mexico *Corresponding authors: E-mails: [email protected]; [email protected]. Accepted: August 11, 2019 Abstract The Gram-negative Acinetobacter genus has several species of clear medical relevance. Many fully sequenced genomes belonging to the genus have been published in recent years; however, there has not been a recent attempt to infer the evolutionary history of Acinetobacter with that vast amount of information. Here, through a phylogenomic approach, we established the most up-to-date view of the evolutionary relationships within this genus and highlighted several cases of poor classification, especially for the very closely related species within the Acinetobacter calcoaceticus–Acinetobacter baumannii complex (Acb complex). Furthermore, we determined appropriate phylogenetic markers for this genus and showed that concatenation of the top 13 gives a very decent reflection of the evolutionary relationships for the genus Acinetobacter. The intersection between our top markers and previously defined universal markers is very small. In general, our study shows that, although there seems to be hardly any universal markers, bespoke phylogenomic approaches can be used to infer the phylogeny of different bacterial genera. We expect that ad hoc phylogenomic approaches will be the standard in the years to come and will provide enough information to resolve intricate evolutionary relationships like those observed in the Acb complex. Key words: phylogenomics, Acinetobacter, bacterial species, evolutionary biology. -

Shouche National Centre for Cell Science A H Sneharani ( [email protected] ) Mangalore University https://orcid.org/0000-0001-7209-7540 Research Article Keywords: dwarf honey bee, Apis orea, gut microbiota, MALDI-TOF MS, 16S rRNA, next generation sequencing Posted Date: April 16th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-225332/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/16 Abstract Honey bees are complex social system, which are highly dynamic having close interactions with their surrounding environment. Gut microbiota of honey bees has a major role in interaction behavior with its environment and health. Apis orea is the primitive among all the honey bees and are indigenous to Indian subcontinent. The study reports the identication and analysis of bacteria in the gut of wild species of honey bee, Apis orea, by culture-based and culture-independent methods. Cultured bacteria were identied and characterized by MALDI-TOF MS and 16S rRNA sequencing. A comprehensive analysis and identication of non-culturable bacteria were performed by 16S rRNA amplicon next generation sequencing. The sequence analysis approach classied gut bacteria into 5 bacterial phyla, 8 families and 10 genera in major. The dominant bacterial taxa identied in Apis orea belonged to Prevotellaceae (52.1%), Enterobacteriaceae (42.7%) and Halobacteriaceae (1.3%). The dominant bacteria belonged to genera of Prevotella, Escherichia-Shigella, Natronomonas, Methylobacterium, Pantoea, Bidobacterium, Enterobacter, Klebsiella, Lactobacillus and Nitrobacter belonging to phyla Bacteroidetes, Proteobacteria, Euryarchaeota, Actinobacteria, and Firmicutes. -
