Elicitors trigger plant defense responses, including phytoalexin production and cell-wall reinforcement. Primary metabolism plays an important role in these responses as it fuels the associated energetic costs and provides precursors for the synthesis of the numerous secondary metabolites involved in defenses against pathogens. In this context, we aimed to determine whether oligosaccharidic elicitors differing in their capacity to activate defense-associated secondary metabolism in grapevine would differently impact primary metabolism...

We introduce an innovative specimen preparation method employing the selectivity of a wet-chemical etching step to improve data quality and success rates in the atom probe analysis of contemporary semiconductor devices. Firstly, on the example of an SiGe fin embedded in SiO2 we demonstrate how the selective removal of SiO2 from the final APT specimen significantly improves accuracy and reliability of the reconstructed data. With the oxide removal, we eliminate the origin of shape artefacts, i.e. the formation of a non-hemispherical tip shape, that are typically observed in the reconstructed volume of complex systems...
