Phosphite (Phi) is used to control oomycete diseases, but the molecular mechanisms underlying Phi-induced resistance to P. capsici are unknown. Thus, Phi-inhibited mycelial growth on strain LT1534 and primed host defence were analysed. We demonstrated that Phi (&amp;gt;5 \u00b5g mL\u20131) had a direct antibiotic effect on mycelial growth and zoospore production, and that mortality and DNA content were significantly reduced by pre-treatment with Phi. In addition, elevated hydrogen peroxide (H2O2) promoted callose deposition and increased the levels of soluble proteins and Capsicum annuum L. pathogenesis-related 1 (CaPR1) expression. Furthermore, Phi (1 g L\u20131) significantly increased the transcription of the antioxidant enzyme genes, and the genes involved in ethylene (ET) and abscisic acid (ABA) biosynthesis, as well as mitogen-activated protein kinase (MAPK) cascades. However, pre-treatment with reactive oxygen species (ROS), ABA and ET biosynthesis inhibitors decreased Phi-induced resistance and reduced the expression of ABA-responsive 1 (CaABR1) and lipoxygenase 1 (CaLOX1). In addition, the decreased ROS and ABA inhibited Phi-induced expression of CaMPK17\u20131. We propose that Phi-induced ROS production, ET and ABA biosynthesis mediate the control of P. capsici, and that ABA functions through CaMPK17\u20131-mediated MAPK signalling.<\/jats:p>","DOI":"10.1071\/fp16006","type":"journal-article","created":{"date-parts":[[2016,5,11]],"date-time":"2016-05-11T18:58:33Z","timestamp":1462993113000},"page":"563-574","source":"Crossref","is-referenced-by-count":22,"title":["Phosphite-induced reactive oxygen species production and ethylene and ABA biosynthesis, mediate the control of Phytophthora capsici in pepper (Capsicum annuum)"],"prefix":"10.1071","volume":"43","author":[{"given":"Peiqing","family":"Liu","sequence":"first","affiliation":[{"name":"AInstitute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."},{"name":"CFujian Key Laboratory for Monitoring and Integrated Management of Crop Pests, Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjin","family":"Li","sequence":"additional","affiliation":[{"name":"AInstitute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."},{"name":"CFujian Key Laboratory for Monitoring and Integrated Management of Crop Pests, Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Lin","sequence":"additional","affiliation":[{"name":"BFujian-Taiwan Joint Innovative Centre for Ecological Control of Crop Pests, Fujian Agriculture and Forestry University, Fuzhou 350 002, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoliang","family":"Chen","sequence":"additional","affiliation":[{"name":"BFujian-Taiwan Joint Innovative Centre for Ecological Control of Crop Pests, Fujian Agriculture and Forestry University, Fuzhou 350 002, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueling","family":"Ding","sequence":"additional","affiliation":[{"name":"AInstitute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."},{"name":"CFujian Key Laboratory for Monitoring and Integrated Management of Crop Pests, Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyong","family":"Weng","sequence":"additional","affiliation":[{"name":"AInstitute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."},{"name":"CFujian Key Laboratory for Monitoring and Integrated Management of Crop Pests, Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou, 350 003, China."},{"name":"DCorresponding authors.
