| 1 | Metabolic responses of Eucalyptus species to different temperature regimes显示文摘Species and hybrids of Eucalyptus are the world's most widely planted hardwood trees. They are cultivated across a wide range of latitudes and therefore environmental conditions. In this context, comprehensive metabolomics approaches have been used to assess how different temperature regimes may affect the metabolism of three species of Eucalyptus, E. dunnii, E. grandis and E. pellita.Young plants were grown for 53 d in the greenhouse and then transferred to growth chambers at 10°C, 20°C or30°C for another 7 d. In all three species the leaf chlorophyll content was positively correlated to temperature, and in E.pellita the highest temperature also resulted in a significant increase in stem biomass. Comprehensive metabolomics was performed using untargeted gas chromatography mass spectrometry(GC-MS) and liquid chromatography(LC)-MS.This approach enabled the comparison of the relativeabundance of 88 polar primary metabolites from GC-MS and625 semi-polar secondary metabolites from LC-MS. Using principal components analysis, a major effect of temperature was observed in each species which was larger than that resulting from the genetic background. Compounds mostly affected by temperature treatment were subsequently selected using partial least squares discriminant analysis and were further identified. These putative annotations indicated that soluble sugars and several polyphenols, including tannins, triterpenes and alkaloids were mostly influenced. | Joao Benhur Mokochinski Paulo Mazzafera Alexandra Christine Helena Frankland Sawaya Roland Mumm Ric Cornelis Hendricus de Vos Robert David Hall | 2018 | Journal of Integrative Plant Biology2018，60，5： | 2 |
| 2 | Quantitative resistance against Bemisia tabaci in Solanum pennellii:Genetics and metabolomics显示文摘The whitefly Bemisia tabaci is a serious threat in tomato cultivation worldwide as all varieties grown today are highly susceptible to this devastating herbivorous insect.Many accessions of the tomato wild relative Solanum pennellii show a high resistance towards B. tabaci. A mapping approach was used to elucidate the genetic background of whiteflyresistance related traits and associated biochemical traits in this species. Minor quantitative trait loci(QTLs) for whitefly adult survival(AS) and oviposition rate(OR) were identified and some were confirmed in an F2BC1 population, where they showed increased percentages of explained variance(more than 30%). Bulked segregant analyses on pools of whiteflyresistant and-susceptible F2 plants enabled the identification of metabolites that correlate either with resistance or susceptibility. Genetic mapping of these metabolites showed that a large number of them co-localize with whiteflyresistance QTLs. Some of these whitefly-resistance QTLs are hotspots for metabolite QTLs. Although a large number of metabolite QTLs correlated to whitefly resistance or susceptibility, most of them are yet unknown compounds and further studies are needed to identify the metabolic pathways and genes involved. The results indicate a direct genetic correlation between biochemical-based resistance characteristics and reduced whitefly incidence in S. pennellii. | Floor van den Oever-van den Elsen Alejandro F.Lucatti Sjaak van Heusden Colette Broekgaarden Roland Mumm Marcel Dicke Ben Vosman | 2016 | Journal of Integrative Plant Biology2016，58，4： | 2 |
