FEBS Letters, EarlyView.Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

FEBS 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.

Green solvents for sample preparation in analytical chemistry
Current Opinion in Green and Sustainable Chemistry, 2017 An analytical procedure comprises two steps: sample preparation mostly extraction (Soxhlet, Dean–Stark, Likens– Nickerson, Blye & Dyer, Folch, leaching, maceration, percolation) and analysis (spectrophotometry, chromatography, spectrometry). Whereas chemical analysis is finished after few minutes, extraction takes at least several hours and requires ...
