This ensures that virulence genes or genes encoding proteins, which promote bacterial fitness in a host environment, are expressed only when needed. Such regulation is in the purview of transcription factors, many of which belong to the ubiquitous multiple antibiotic resistance regulator (MarR) protein family. PecS proteins constitute a subset of this large protein family. PecS has likely been distributed by horizontal gene transfer, along with the divergently encoded efflux pump PecM, suggesting its integration into existing gene regulatory networks. Here, we discuss the roles of PecS in the regulation of genes associated with virulence and fitness of bacterial plant pathogens. A comparison of phenotypes and differential gene expression associated with the disruption of\n              <jats:italic>pecS<\/jats:italic>\n              shows that functional consequences of PecS integration into existing transcriptional networks are highly variable, resulting in distinct PecS regulons. Although PecS universally binds to the\n              <jats:italic>pecS-pecM<\/jats:italic>\n              intergenic region to repress the expression of both genes, binding modes differ. A particularly relaxed sequence preference appears to apply for\n              <jats:italic>Dickeya dadantii<\/jats:italic>\n              PecS, perhaps to optimize its integration as a global regulator and regulate genes ancestral to the acquisition of\n              <jats:italic>pecS-pecM<\/jats:italic>\n              . Even inducing ligands for PecS are not universally conserved. It appears that PecS function has been optimized to match the unique regulatory needs of individual bacterial species and that its roles must be appreciated in the context of the regulatory networks into which it was recruited.\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.1128\/jb.00302-24","type":"journal-article","created":{"date-parts":[[2024,9,17]],"date-time":"2024-09-17T17:05:31Z","timestamp":1726592731000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["Regulation of bacterial virulence genes by PecS family transcription factors"],"prefix":"10.1128","volume":"206","author":[{"given":"George C.","family":"Nwokocha","sequence":"first","affiliation":[{"name":"Corteva Agriscience, Johnston, Iowa, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arpita","family":"Ghosh","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4390-0354","authenticated-orcid":true,"given":"Anne","family":"Grove","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-micro-032521-025954"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/femsre\/fuz001"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1080\/10409238.2017.1344612"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/pro.3769"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/pro.588"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2958.1994.tb00389.x"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1462-2920.2011.02566.x"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmb.2010.07.053"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-019-39095-4"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/acschembio.6b00168"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1099\/mic.0.000185"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1128\/JB.00854-13"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/10.supplement_2.s274"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/1462-2920.13611"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1364-3703.2010.00625.x"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/mmi.12929"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1111\/mpp.12427"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1104\/pp.109.139089"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.3390\/microorganisms9061227"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1128\/jb.179.11.3500-3508.1997"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M110.114710"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1093\/plcell\/koac040"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1089\/ars.2017.7442"},{"key":"e_1_3_2_25_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-micro-091014-104322"},{"key":"e_1_3_2_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.csbj.2017.06.001"},{"key":"e_1_3_2_27_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-024-07487-w"},{"key":"e_1_3_2_28_2","doi-asserted-by":"publisher","DOI":"10.1111\/mmi.12156"},{"key":"e_1_3_2_29_2","doi-asserted-by":"publisher","DOI":"10.1038\/nchembio.1380"},{"key":"e_1_3_2_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.molcel.2007.09.016"},{"key":"e_1_3_2_31_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M405586200"},{"key":"e_1_3_2_32_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmb.2006.05.005"},{"key":"e_1_3_2_33_2","doi-asserted-by":"publisher","DOI":"10.1021\/bi500219t"},{"key":"e_1_3_2_34_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmb.2005.05.027"},{"key":"e_1_3_2_35_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbrc.2022.05.034"},{"key":"e_1_3_2_36_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-5-113"},{"key":"e_1_3_2_37_2","first-page":"309","article-title":"The PecM protein of the phytopathogenic bacterium Erwinia chrysanthemi, membrane topology and possible involvement in the efflux of the blue pigment indigoidine","volume":"3","author":"Rouanet C","year":"2001","unstructured":"Rouanet C, Nasser W. 2001.
