Detergent effect on cytochrome b559 electron paramagnetic resonance signals in the photosystem II reaction centre
(Wiley, 2003)
Detergent effect on Cytochrome b559 from spinach photosystem II was studied by electron paramagnetic resonance (EPR) spectroscopy in D1-D2-Cyt b559 complex preparations. Various n-dodecyl-β-D-maltoside ...

PRC1 is taking the lead in PcG repression
(Blackwell Publishing, 2015-03-06)
Polycomb group (PcG) proteins constitute a major epigenetic mechanism for gene repression throughout the plant life. For a long time, the PcG mechanism has been proposed to follow a hierarchical recruitment of PcG repressive ...

Analysis of expression of the argC and argD genes in the cyanobacterium Anabaena sp. strain PCC 7120.
(American Society for Microbiology, 1994)
A cloned DNA fragment from Anabaena sp. strain PCC 7120 that complements an arginine auxotrophic mutant from the same organism was found to include an open reading frame encoding a 427-residue polypeptide that is homologous ...

Trans-oligomerization of duplicated aminoacyl-tRNA synthetases maintains genetic code fidelity under stress
(Oxford University Press, 2015)
Aminoacyl-tRNA synthetases (aaRSs) play a key role in deciphering the genetic message by producing charged tRNAs and are equipped with proofreading mechanisms to ensure correct pairing of tRNAs with their cognate amino ...

Stress-related biomolecular condensates in plants
(American Society of Plant Biologists, 2023-09)
Biomolecular condensates are membraneless organelle-like structures that can concentrate molecules and often form through liquid-liquid phase separation. Biomolecular condensate assembly is tightly regulated by developmental ...

Sulfide promotes tolerance to drought through protein persulfidation in Arabidopsis
(Oxford University Press, 2023-08-17)
Hydrogen sulfide (H2S) is a signaling molecule that regulates essential plant processes. In this study, the role of H2S during drought was analysed, focusing on the underlying mechanism. Pretreatments with H2S before ...

NsrR1, a Nitrogen stress-repressed sRNA, contributes to the regulation of nblA in Nostoc sp. PCC 7120
(Frontiers Media, 2018-09-24)
Small regulatory RNAs (sRNAs) are currently considered as major post-transcriptional regulators of gene expression in bacteria. The interplay between sRNAs and transcription factors leads to complex regulatory networks in ...
