(Pentatomidae) DISSERTATION Presented
Genome Evolution During Development of Symbiosis in Extracellular Mutualists of Stink Bugs (Pentatomidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Alejandro Otero-Bravo Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2020 Dissertation Committee: Zakee L. Sabree, Advisor Rachelle Adams Norman Johnson Laura Kubatko Copyrighted by Alejandro Otero-Bravo 2020 Abstract Nutritional symbioses between bacteria and insects are prevalent, diverse, and have allowed insects to expand their feeding strategies and niches. It has been well characterized that long-term insect-bacterial mutualisms cause genome reduction resulting in extremely small genomes, some even approaching sizes more similar to organelles than bacteria. While several symbioses have been described, each provides a limited view of a single or few stages of the process of reduction and the minority of these are of extracellular symbionts. This dissertation aims to address the knowledge gap in the genome evolution of extracellular insect symbionts using the stink bug – Pantoea system. Specifically, how do these symbionts genomes evolve and differ from their free- living or intracellular counterparts? In the introduction, we review the literature on extracellular symbionts of stink bugs and explore the characteristics of this system that make it valuable for the study of symbiosis. We find that stink bug symbiont genomes are very valuable for the study of genome evolution due not only to their biphasic lifestyle, but also to the degree of coevolution with their hosts. i In Chapter 1 we investigate one of the traits associated with genome reduction, high mutation rates, for Candidatus ‘Pantoea carbekii’ the symbiont of the economically important pest insect Halyomorpha halys, the brown marmorated stink bug, and evaluate its potential for elucidating host distribution, an analysis which has been successfully used with other intracellular symbionts. -

Tsetse fly evolution, genetics and the trypanosomiases - A review Abstract This reviews work published since 2007. Relative efforts devoted to the agents of African trypanosomiasis and their tsetse fly vectors are given by the numbers of PubMed accessions. In the last 10 years PubMed citations number 3457 for Trypanosoma brucei and 769 for Glossina. The development of simple sequence repeats and single nucleotide polymorphisms afford much higher resolution of Glossina and Trypanosoma population structures than heretofore. Even greater resolution is offered by partial and whole genome sequencing. Reproduction in T. brucei sensu lato is principally clonal although genetic recombination in tsetse salivary glands has been demonstrated in T. b. brucei and T. b. rhodesiense but not in T. b. -
Mixta Gen. Nov., a New Genus in the Erwiniaceae
RESEARCH ARTICLE Palmer et al., Int J Syst Evol Microbiol 2018;68:1396–1407 DOI 10.1099/ijsem.0.002540 Mixta gen. nov., a new genus in the Erwiniaceae Marike Palmer,1,2 Emma T. Steenkamp,1,2 Martin P. A. Coetzee,2,3 Juanita R. Avontuur,1,2 Wai-Yin Chan,1,2,4 Elritha van Zyl,1,2 Jochen Blom5 and Stephanus N. Venter1,2,* Abstract The Erwiniaceae contain many species of agricultural and clinical importance. Although relationships among most of the genera in this family are relatively well resolved, the phylogenetic placement of several taxa remains ambiguous. In this study, we aimed to address these uncertainties by using a combination of phylogenetic and genomic approaches. Our multilocus sequence analysis and genome-based maximum-likelihood phylogenies revealed that the arsenate-reducing strain IMH and plant-associated strain ATCC 700886, both previously presumptively identified as members of Pantoea, represent novel species of Erwinia. Our data also showed that the taxonomy of Erwinia teleogrylli requires revision as it is clearly excluded from Erwinia and the other genera of the family. Most strikingly, however, five species of Pantoea formed a distinct clade within the Erwiniaceae, where it had a sister group relationship with the Pantoea + Tatumella clade. By making use of gene content comparisons, this new clade is further predicted to encode a range of characters that it shares with or distinguishes it from related genera. We thus propose recognition of this clade as a distinct genus and suggest the name Mixta in reference to the diverse habitats from which its species were obtained, including plants, humans and food products. -
Pest Categorisation of Pantoea Stewartii Subsp. Stewartii
SCIENTIFIC OPINION ADOPTED: 21 June 2018 doi: 10.2903/j.efsa.2018.5356 Pest categorisation of Pantoea stewartii subsp. stewartii EFSA Panel on Plant Health (EFSA PLH Panel), Michael Jeger, Claude Bragard, Thierry Candresse, Elisavet Chatzivassiliou, Katharina Dehnen-Schmutz, Gianni Gilioli, Jean-Claude Gregoire, Josep Anton Jaques Miret, Alan MacLeod, Maria Navajas Navarro, Bjorn€ Niere, Stephen Parnell, Roel Potting, Trond Rafoss, Vittorio Rossi, Gregor Urek, Ariena Van Bruggen, Wopke Van der Werf, Jonathan West, Stephan Winter, Charles Manceau, Marco Pautasso and David Caffier Abstract Following a request from the European Commission, the EFSA Plant Health Panel performed a pest categorisation of Pantoea stewartii subsp. stewartii (hereafter P. s . subsp. stewartii). P. s . subsp. stewartii is a Gram-negative bacterium that causes Stewart’s vascular wilt and leaf blight of sweet corn and maize, a disease responsible for serious crop losses throughout the world. The bacterium is endemic to the USA and is now present in Africa, North, Central and South America, Asia and Ukraine. In the EU, it is reported from Italy with a restricted distribution and under eradication. The bacterium is regulated according to Council Directive 2000/29/EC (Annex IIAI) as a harmful organism whose introduction and spread in the EU is banned on seeds of Zea mays. Other reported potential host plants include various species of the family Poaceae, including weeds, rice (Oryza sativa), oat (Avena sativa) and common wheat (Triticum aestivum), as well as jackfruit (Artocarpus heterophyllus), the ornamental Dracaena sanderiana and the palm Bactris gasipaes, but there is uncertainty about whether these are hosts of P. -

Mobolaji Adeolu,† Seema Alnajar,† Sohail Naushad and Radhey S. Gupta Correspondence Department of Biochemistry and Biomedical Sciences, McMaster University, Hamilton, Ontario, Radhey S. Gupta L8N 3Z5, Canada [email protected] Understanding of the phylogeny and interrelationships of the genera within the order ‘Enterobacteriales’ has proven difficult using the 16S rRNA gene and other single-gene or limited multi-gene approaches. In this work, we have completed comprehensive comparative genomic analyses of the members of the order ‘Enterobacteriales’ which includes phylogenetic reconstructions based on 1548 core proteins, 53 ribosomal proteins and four multilocus sequence analysis proteins, as well as examining the overall genome similarity amongst the members of this order. The results of these analyses all support the existence of seven distinct monophyletic groups of genera within the order ‘Enterobacteriales’. In parallel, our analyses of protein sequences from the ‘Enterobacteriales’ genomes have identified numerous molecular characteristics in the forms of conserved signature insertions/deletions, which are specifically shared by the members of the identified clades and independently support their monophyly and distinctness. Many of these groupings, either in part or in whole, have been recognized in previous evolutionary studies, but have not been consistently resolved as monophyletic entities in 16S rRNA gene trees. The work presented here represents the first comprehensive, genome- scale taxonomic analysis of the entirety of the order ‘Enterobacteriales’. -

ARTICLE INFO ABSTRACT Article history: Midgut transgenic bacteria can be used to express and deliver anti-parasite molecules in malaria vector mosquitoes Received 24 October 2019 to reduce transmission. Hence, it is necessary to know the symbiotic bacteria of the microbiota of the midgut Accepted 23 April 2020 to identify those that can be used to interfering in the vector competence of a target mosquito population. Available online 08 June 2020 The bacterial communities associated with the abdomen of Nyssorhynchus braziliensis (Chagas) (Diptera: Associate Editor: Mário Navarro-Silva Culicidae) and Nyssorhynchus darlingi (Root) (Diptera: Culicidae) were identified using Illumina NGS sequencing of the V4 region of the 16S rRNA gene. Wild females were collected in rural and periurban communities in the Brazilian Amazon. Proteobacteria was the most abundant group identified in both species. Asaia (Rhodospirillales: Keywords: Acetobacteraceae) and Serratia (Enterobacterales: Yersiniaceae) were detected in Ny. braziliensis for the first time Vectors and its presence was confirmed in Ny. darlingi. Malaria Amazon Although the malaria burden has decreased worldwide, the disease bites by the use of insecticide-treated bed nets, and insecticide indoor still imposes enormous suffering for human populations in the majority residual spraying (Baird, 2017; Shretta et al., 2017; WHO, 2018).
