In the present study, we demonstrated that YbeY in\n            <jats:named-content content-type=\"genus-species\">Brucella abortus<\/jats:named-content>\n            is linked to a variety of important activities, including proper cellular morphology, mRNA transcript levels, and virulence. Deletion of\n            <jats:italic>ybeY<\/jats:italic>\n            in\n            <jats:named-content content-type=\"genus-species\">B. abortus<\/jats:named-content>\n            led to a small-colony phenotype when the bacteria were grown on agar medium, as well as to significant aberrations in the morphology of the bacterial cell as evidenced by electron microscopy. Additionally, compared to the parental strain, the \u0394\n            <jats:italic>ybeY<\/jats:italic>\n            strain was significantly attenuated in both macrophage and mouse models of infection. The \u0394\n            <jats:italic>ybeY<\/jats:italic>\n            strain also showed increased sensitivities to several\n            <jats:italic>in vitro<\/jats:italic>\n            -applied stressors, including bile acid, hydrogen peroxide, SDS, and paraquat. Transcriptomic analysis revealed that a multitude of mRNA transcripts are dysregulated in the \u0394\n            <jats:italic>ybeY<\/jats:italic>\n            strain, and many of the identified mRNAs encode proteins involved in metabolism, nutrient transport, transcriptional regulation, and flagellum synthesis. We subsequently constructed gene deletion strains of the most highly dysregulated systems, and several of the YbeY-linked gene deletion strains exhibited defects in the ability of the bacteria to survive and replicate in primary murine macrophages. Taken together, these data establish a clear role for YbeY in the biology and virulence of\n            <jats:named-content content-type=\"genus-species\">Brucella<\/jats:named-content>\n            ; moreover, this work further illuminates the highly varied roles of this widely conserved endoribonuclease in bacteria.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            <jats:named-content content-type=\"genus-species\">Brucella<\/jats:named-content>\n            spp. are highly efficient bacterial pathogens of animals and humans, causing significant morbidity and economic loss worldwide, and relapse of disease often occurs following antibiotic treatment of human brucellosis. As such, novel therapeutic strategies to combat\n            <jats:named-content content-type=\"genus-species\">Brucella<\/jats:named-content>\n            infections are needed. Ribonucleases in the brucellae are understudied, and these enzymes represent elements that may be potential targets for future treatment approaches. The present work demonstrates the importance of the YbeY endoribonuclease for cellular morphology, efficient control of mRNA levels, and virulence in\n            <jats:named-content content-type=\"genus-species\">B. abortus<\/jats:named-content>\n            . Overall, the results of this study advance our understanding of the critical roles of YbeY in the pathogenesis of the intracellular brucellae and expand our understanding of this highly conserved RNase.\n          <\/jats:p>","DOI":"10.1128\/jb.00105-18","type":"journal-article","created":{"date-parts":[[2018,4,6]],"date-time":"2018-04-06T09:54:05Z","timestamp":1523008445000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":16,"title":["Endoribonuclease YbeY Is Linked to Proper Cellular Morphology and Virulence in Brucella abortus"],"prefix":"10.1128","volume":"200","author":[{"given":"James A.","family":"Budnick","sequence":"first","affiliation":[{"name":"Department of Biomedical Sciences and Pathobiology, VA-MD College of Veterinary Medicine, Virginia Tech, Blacksburg, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren M.","family":"Sheehan","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences and Pathobiology, VA-MD College of Veterinary Medicine, Virginia Tech, Blacksburg, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer M.","family":"Colquhoun","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, University of Rochester Medical Center, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul M.","family":"Dunman","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, University of Rochester Medical Center, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Graham C.","family":"Walker","sequence":"additional","affiliation":[{"name":"Department of Biology, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"II","given":"R.
