Although differences in the responsivity occur within species, no plant tested so far could be considered resistant to\n                    <jats:italic>R. fascians<\/jats:italic>\n                    strain D188 infection. Here, we observed that members of the genus\n                    <jats:italic>Dalbergia<\/jats:italic>\n                    , which belong to the Fabaceae, did not develop leafy galls when challenged with\n                    <jats:italic>R. fascians<\/jats:italic>\n                    and we set out to unravel the mechanism of this recalcitrance. Whereas organic extracts of\n                    <jats:italic>Dalbergia<\/jats:italic>\n                    tissues exhibited toxicity towards the bacteria, more importantly, dichloromethane bark extracts inhibited the induction of bacterial virulence gene expression without any apparent loss of viability, illustrating that resistance is likely multifactorial. The virulence quencher was identified as a new prenylated isoflavanone, termed perbergin, and specifically targeted the AttR regulon (a LysR\u2010type transcriptional regulator) which is imperative for the switch of\n                    <jats:italic>R. fascians<\/jats:italic>\n                    from an epiphytic to a pathogenic lifestyle. The mode of action of perbergin demonstrated that just like in Gram\u2010negative host\u2013microbe interactions, also in Gram\u2010positive phytopathogens autoregulation is being targeted by the plant as an efficient means of defence. Moreover, the identification of perbergin opens the path to disease control in affected nurseries.\n                  <\/jats:p>","DOI":"10.1111\/j.1462-2920.2011.02424.x","type":"journal-article","created":{"date-parts":[[2011,2,17]],"date-time":"2011-02-17T21:19:27Z","timestamp":1297977567000},"page":"1236-1252","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Virulence quenching with a prenylated isoflavanone renders the Malagasy legume\n                    <i>Dalbergia pervillei<\/i>\n                    resistant to\n                    <i>Rhodococcus fascians<\/i>"],"prefix":"10.1111","volume":"13","author":[{"given":"Sanda","family":"Rajaonson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivier M.","family":"Vandeputte","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danny","family":"Vereecke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Kiendrebeogo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliane","family":"Ralambofetra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"St\u00e9vigny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Duez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Rabemanantsoa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adeline","family":"Mol","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Billo","family":"Diallo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie","family":"Baucher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mondher","family":"El Jaziri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,2,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1071\/FP09304"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1187740"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1171661"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1462399410001420"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0031-9422(01)00009-7"},{"key":"e_1_2_6_7_1","first-page":"321","volume-title":"The Leguminosae of Madagascar","author":"Bosser J.","year":"2002"},{"key":"e_1_2_6_8_1","first-page":"209","article-title":"Esp\u00e8ces nouvelles dans le genre Dalbergia (Fabaceae, Papilionoideae) \u00e0 Madagascar","volume":"27","author":"Bosser J.","year":"2005","journal-title":"Adansonia"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.2174\/092986709789057662"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1574-6941.2009.00745.x"},{"key":"e_1_2_6_11_1","first-page":"29","article-title":"Sweet pea fasciation, a form of crowngall","volume":"17","author":"Brown N.A.","year":"1927","journal-title":"Phytopathology"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1128\/jb.175.17.5477-5487.1993"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.251465298"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1094\/MPMI.2002.15.4.398"},{"key":"e_1_2_6_15_1","first-page":"369","article-title":"Amazonian plant crude extract screening for activity against multidrug\u2010resistant bacteria","volume":"12","author":"Correia A.F.","year":"2008","journal-title":"Eur Rev Med Pharmacol Sci"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1460-2075.1992.tb05116.x"},{"key":"e_1_2_6_17_1","first-page":"480","volume-title":"Floriculture, Ornamental, and Plant Biotechnology: Advances and Topical Issues","author":"Depuydt S.","year":"2008"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1104\/pp.107.113969"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1104\/pp.108.131805"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1104\/pp.108.131797"},{"key":"e_1_2_6_21_1","unstructured":"Du Puy D.J.(1998)Dalbergia pervillei.
