Quantitative paper chromatography of lipids [PDF]

open access: yesExperientia, 1956
Ein qualitatives Verfahren zur papierchromatographischen Trennung von Fettsauren und Derivaten liess sich zur quantitativen Bestimmung ausbauen. Die Methode hat eine Fehlergrenze von etwa ± 5% und ist unabhangig von den funktionellen Gruppen der Molekule. Sie ist fur gesattigte Di- und Triglyceride nicht direkt anwendbar.

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

open access: yesFEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.
