Unlabelled: Production and isolation of recombinant proteins are key steps in modern Molecular Biology. Expression vectors and platforms for various hosts, including both prokaryotic and eukaryotic systems, have been used. In basic plant research, Arabidopsis thaliana is the central model for which a wealth of genetic and genomic resources is available, and enormous knowledge has been accumulated over the past years - especially since elucidation of its genome in 2000. However, until recently an Arabidopsis platform had been lacking for preparative-scale production of homologous recombinant proteins. We recently established an Arabidopsis-based super-expression system, and used it for a structural pilot study of a multi-subunit integral membrane protein complex. This review summarizes the benefits and further potential of the model plant system for protein productions.
Abbreviations: Nb, Nicotiana benthamiana; OT, oligosaccharyltransferase.

Recent advancements in fluorescence-based biosensor technologies have enabled more precise and accurate Förster Resonance Energy Transfer (FRET) imaging within Agrobacterium-mediated plant transformation systems. However, the application of FRET imaging in plant tissues remains hindered by significant challenges, particularly the time-intensive process of generating transgenic lines and the complications arising from tissue autofluorescence. In contrast, protoplast-based FRET imaging offers a rapid and efficient platform for functional screening and analysis, making it an essential tool for plant research.

N-degrons are amino-terminal degradation signals. Non-acetylated first residues with bulky side chains were the first discovered N-degrons. In yeast, their ability to destabilize a protein depends on ubiquitin ligase Ubr1, which has a binding site for basic first residues, the UBR box, and one for hydrophobic first residues, the N domain.

Waterlogging stress is a significant abiotic factor that severely limits plant growth and development. Identifying genes involved in the waterlogging stress response and understanding the mechanisms by which plants resist waterlogging stress are therefore critical. In this study, we identified a specific role for two transcription factors, BPC1 and BPC2, in the waterlogging stress response of Arabidopsis thaliana.

Class I glutaredoxins (GRXs) are nearly ubiquitous proteins that catalyse the glutathione (GSH)-dependent reduction of mainly glutathionylated substrates. In land plants, a third class of GRXs has evolved (class III). Class III GRXs regulate the activity of TGA transcription factors through yet unexplored mechanisms.
