The mechanisms by which\n S<\/jats:styled-content>\n i exerts its prophylactic role remain enigmatic, although a prevailing hypothesis suggests that\n S<\/jats:styled-content>\n i positively influences priming. Attempts to decipher\n S<\/jats:styled-content>\n i properties have been limited to plants able to absorb\n S<\/jats:styled-content>\n i, which excludes the model plant\n A<\/jats:styled-content>\n rabidopsis because it lacks\n S<\/jats:styled-content>\n i influx transporters. In this work, we were able to engineer\n A<\/jats:styled-content>\n rabidopsis plants with an\n S<\/jats:styled-content>\n i transporter from wheat (\n TaLsi1<\/jats:styled-content>\n ) and to exploit mutants (\n pad4<\/jats:italic>\n and\n sid2<\/jats:italic>\n ) deficient in salicylic acid (\n SA<\/jats:styled-content>\n )\u2010dependent defence responses to study their phenotypic response and changes in defence expression against\n \n G<\/jats:styled-content>\n olovinomyces cichoracearum\n <\/jats:italic>\n (\n \n G<\/jats:styled-content>\n c\n <\/jats:italic>\n ) following\n S<\/jats:styled-content>\n i treatment. Our results showed that\n \n TaLsi1<\/jats:styled-content>\n <\/jats:italic>\n plants contained significantly more\n S<\/jats:styled-content>\n i and were significantly more resistant to\n \n G<\/jats:styled-content>\n c\n <\/jats:italic>\n infection than control plants when treated with\n S<\/jats:styled-content>\n i, the first such demonstration in a plant transformed with a heterologous\n S<\/jats:styled-content>\n i transporter. The resistant plants accumulated higher levels of\n SA<\/jats:styled-content>\n and expressed higher levels of transcripts encoding defence genes, thus suggesting a role for\n S<\/jats:styled-content>\n i in the process. However,\n \n TaLsi1<\/jats:styled-content>\n pad4\n <\/jats:italic>\n and\n \n TaLsi1<\/jats:styled-content>\n sid2\n <\/jats:italic>\n plants were also more resistant to\n \n G<\/jats:styled-content>\n c\n <\/jats:italic>\n than were\n pad4<\/jats:italic>\n and\n sid2<\/jats:italic>\n plants following\n S<\/jats:styled-content>\n i treatment. Analysis of the resistant phenotypes revealed a significantly reduced production of\n SA<\/jats:styled-content>\n and expression of defence genes comparable with susceptible controls. These results indicate that\n S<\/jats:styled-content>\n i contributes to Arabidopsis defence priming following pathogen infection, but highlight that\n S<\/jats:styled-content>\n i will confer protection even when priming is altered. We conclude that\n S<\/jats:styled-content>\n i\u2010mediated protection involves mechanisms other than\n SA<\/jats:styled-content>\n \u2010dependent defence responses.\n <\/jats:p>","DOI":"10.1111\/mpp.12213","type":"journal-article","created":{"date-parts":[[2014,10,24]],"date-time":"2014-10-24T04:12:36Z","timestamp":1414123956000},"page":"572-582","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":172,"title":["Silicon\u2010mediated resistance of\n A<\/scp>\n rabidopsis against powdery mildew involves mechanisms other than the salicylic acid (\n SA<\/scp>\n )\u2010dependent defence pathway"],"prefix":"10.1111","volume":"16","author":[{"given":"Julien","family":"Vivancos","sequence":"first","affiliation":[{"name":"D\u00e9partement de Phytologie Facult\u00e9 des Sciences de l'Agriculture et de l'Alimentation Universit\u00e9 Laval Qu\u00e9bec QC Canada G1V 0A6"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Labb\u00e9","sequence":"additional","affiliation":[{"name":"D\u00e9partement de Phytologie Facult\u00e9 des Sciences de l'Agriculture et de l'Alimentation Universit\u00e9 Laval Qu\u00e9bec QC Canada G1V 0A6"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James G.","family":"Menzies","sequence":"additional","affiliation":[{"name":"Agriculture and Agri\u2010Food Canada 101 Route 100 Morden MB Canada R6M 1Y5"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard R.","family":"B\u00e9langer","sequence":"additional","affiliation":[{"name":"D\u00e9partement de Phytologie Facult\u00e9 des Sciences de l'Agriculture et de l'Alimentation Universit\u00e9 Laval Qu\u00e9bec QC Canada G1V 0A6"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,12,15]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-313X.1996.09030341.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.plantsci.2011.01.019"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1094\/PD-79-0329"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1094\/PHYTO.2003.93.4.402"},{"key":"e_1_2_6_6_1","volume-title":"La R\u00e9sistance chez les Plantes.
