MetabolomicsFunctional metabolomics as a tool to analyze Mediator function and structure in plants
Mediator is a multiprotein transcriptional co-regulator complex composed of four modules; Head, Middle, Tail, and Kinase. It conveys signals from promoter-bound transcriptional regulators to RNA polymerase II and thus plays an essential role in eukaryotic gene regulation. We describe subunit localiz...

MetabolomicsOverexpression of vesicle-associated membrane protein PttVAP27-17 as a tool to improve biomass production and the overall saccharification yields in Populus trees

Background

Bioconversion of wood into bioproducts and biofuels is hindered by the recalcitrance of woody raw material to bioprocesses such as enzymatic saccharification. Targeted modification of the chemical composition of the feedstock can improve saccharification but this gain is often abr...

MetabolomicsA metabolite roadmap of the wood-forming tissue in Populus tremula (UPLC-MS assay; Wood ring and extraxylary tissue)

Wood, or secondary xylem, is the product of xylogenesis, a developmental process that begins with the proliferation of cambial derivatives and ends with mature xylem fibers and vessels with lignified secondary cell walls. Fully mature xylem has undergone a series of cellular processes, including ...

MetabolomicsA metabolite roadmap of the wood-forming tissue in Populus tremula (GC-MS assay; Wood ring and extraxylary tissue)

Wood, or secondary xylem, is the product of xylogenesis, a developmental process that begins with the proliferation of cambial derivatives and ends with mature xylem fibers and vessels with lignified secondary cell walls. Fully mature xylem has undergone a series of cellular processes, including ...

MetabolomicsMulti-omics analysis of xylem sap uncovers dynamic modulation of poplar defenses by ammonium and nitrate
Xylem sap is the major transport route for nutrients from roots to shoots. In the present study, we investigated how variations in nitrogen (N) nutrition affected the metabolome and proteome of xylem sap and the growth of the xylem endophyte Brennaria salicis, and we also report transcriptional re-w...

MetabolomicsA metabolite roadmap of the wood-forming tissue in Populus tremula (UPLC-MS assay; Wood fibre and ray cell tissue)

Wood, or secondary xylem, is the product of xylogenesis, a developmental process that begins with the proliferation of cambial derivatives and ends with mature xylem fibers and vessels with lignified secondary cell walls. Fully mature xylem has undergone a series of cellular processes, including ...

MetabolomicsA metabolomic study of Gomphrena agrestis in Brazilian Cerrado suggests drought-adaptive strategies on metabolism
Drought is the main factor that limits the distribution and productivity of plant species. In the Brazilian Cerrado, the vegetation is adapted to a seasonal climate with long- and short-term periods of drought. To analyze the metabolic strategies under such conditions, a metabolomic approach was use...

MetabolomicsA multi-omics approach reveals functions of Secretory Carrier-Associated Membrane Proteins in wood formation of Populus trees
Secretory Carrier-Associated Membrane Proteins (SCAMPs) are highly conserved proteins that are involved in membrane trafficking. An integrated approach was taken to elucidate function of SCAMPs in wood formation of Populus trees. The metabolomics analyses were performed in woody tissues of transgeni...

MetabolomicsThe glycosyltransferase UGT76B1 modulates N-hydroxy-pipecolic acid homeostasis and plant immunity
The trade-off between growth and defense is a critical aspect of plant immunity. Therefore, the plant immune response needs to be tightly regulated. Salicylic acid (SA) is an important plant hormone regulating defense against biotrophic pathogens. Recently, N-hydroxy-pipecolic acid (NHP) was identif...
