In this study, transgenic hybrid poplar (Populus × euramericana 'Guariento') harboring five effector genes (vgb, SacB, JERF36, BtCry3A and OC-I) were subjected to drought, salinity, waterlogging and insect stressors in greenhouse or laboratory conditions. Field trials were also conducted to investigate long-term effects of transgenic trees on insects and salt tolerance in the transformants. In greenhouse studies, two transgenic lines D5-20 and D5-21 showed improved growth, as evidenced by greater height and basal diameter increments and total biomass relative to the control plants after drought or salt stress treatments. The improved tolerance to drought and salt was primarily attributed to greater instantaneous water use efficiency (WUEi) in the transgenic trees. The chlorophyll concentrations tended to be higher in the transgenic lines under drought or saline conditions. Transformed trees in drought conditions accumulated more fructan and proline and had increased Fv/Fm ratios (maximum quantum yield of photosystem II) under waterlogging stress. Insect-feeding assays in the laboratory revealed a higher total mortality rate and lower exuviation index of leaf beetle [Plagiodera versicolora (Laicharting)] larvae fed with D5-21 leaves, suggesting enhanced insect resistance in the transgenic poplar. In field trials, the dominance of targeted insects on 2-year-old D5-21 transgenic trees was substantially lower than that of the controls, indicating enhanced resistance to Coleoptera. The average height and DBH (diameter at breast height) of 2.5-year-old transgenic trees growing in naturally saline soil were 3.80% and 4.12% greater than those of the control trees, but these increases were not significant. These results suggested that multiple stress-resistance properties in important crop tree species could be simultaneously improved, although additional research is needed to fully understand the relationships between the altered phenotypes and the function of each transgene in multigene transformants.", "link"=>"http://www.mendeley.com/research/expression-multiple-resistance-genes-enhances-tolerance-environmental-stressors-transgenic-poplar-po-2", "reader_count"=>23, "reader_count_by_academic_status"=>{"Unspecified"=>1, "Professor > Associate Professor"=>4, "Researcher"=>6, "Student > Ph.

In this study, transgenic hybrid poplar (<em>Populus</em> × <em>euramericana</em> ‘Guariento’) harboring five effector genes (<em>vgb</em>, <em>SacB</em>, <em>JERF36</em>, <em>BtCry3A</em> and <em>OC-I</em>) were subjected to drought, salinity, waterlogging and insect stressors in greenhouse or laboratory conditions. Field trials were also conducted to investigate long-term effects of transgenic trees on insects and salt tolerance in the transformants. In greenhouse studies, two transgenic lines D5-20 and D5-21 showed improved growth, as evidenced by greater height and basal diameter increments and total biomass relative to the control plants after drought or salt stress treatments. The improved tolerance to drought and salt was primarily attributed to greater instantaneous water use efficiency (WUEi) in the transgenic trees. The chlorophyll concentrations tended to be higher in the transgenic lines under drought or saline conditions. Transformed trees in drought conditions accumulated more fructan and proline and had increased <em>Fv</em>/<em>Fm</em> ratios (maximum quantum yield of photosystem II) under waterlogging stress. Insect-feeding assays in the laboratory revealed a higher total mortality rate and lower exuviation index of leaf beetle [<em>Plagiodera versicolora</em> (Laicharting)] larvae fed with D5-21 leaves, suggesting enhanced insect resistance in the transgenic poplar. In field trials, the dominance of targeted insects on 2-year-old D5-21 transgenic trees was substantially lower than that of the controls, indicating enhanced resistance to Coleoptera. The average height and DBH (diameter at breast height) of 2.5-year-old transgenic trees growing in naturally saline soil were 3.80% and 4.12% greater than those of the control trees, but these increases were not significant. These results suggested that multiple stress-resistance properties in important crop tree species could be simultaneously improved, although additional research is needed to fully understand the relationships between the altered phenotypes and the function of each transgene in multigene transformants.</p> </div>", "links"=>[], "tags"=>["genes", "enhances", "stressors", "transgenic", "poplar"], "article_id"=>133468, "categories"=>["Biotechnology", "Ecology", "Cell Biology"], "users"=>["Xiaohua Su", "Yanguang Chu", "Huan Li", "Yingjie Hou", "Bingyu Zhang", "Qinjun Huang", "Zanmin Hu", "Rongfeng Huang", "Yingchuan Tian"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0024614.s001", "https://dx.doi.org/10.1371/journal.pone.0024614.s002"], "stats"=>{"downloads"=>2, "page_views"=>6, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/Expression_of_Multiple_Resistance_Genes_Enhances_Tolerance_to_Environmental_Stressors_in_Transgenic_Poplar_Populus_euramericana_Guariento_/133468", "title"=>"Expression of Multiple Resistance Genes Enhances Tolerance to Environmental Stressors in Transgenic Poplar (<em>Populus</em> × <em>euramericana</em> ‘Guariento’)", "pos_in_sequence"=>0, "defined_type"=>4, "published_date"=>"2011-09-09 00:57:48"}
