Redox switches regulate photosynthetic reactions and are mediated by conserved cysteine pairs, activated by reduction under light and deactivated by oxidation in the dark. Those reactions are mediated by thioredoxins (Trx). Usually, only plastidic and not cytosolic isozymes show these redox switches.…

Zhi Li, Andan Zhu, et al. compare inbred and hybrid lines to explore how daily changes in metabolic pathways affect hybrid vigor. The Plant Cell https://doi.org/10.1105/tpc.20.00320  Background: Heterosis or hybrid vigor refers to the superior growth or fitness in the hybrid progeny compared to one…

As heterotrophs, we are what we eat. One of the UN Sustainable Development Goals is to end all forms of hunger, including the “hidden hunger” that results from nutrient deficiencies. Van Der Straeten et al. provide an overview of biofortification strategies. They review current successes from…

The movement of electrons between molecules and organelles via redox reactions is a cornerstone of cellular metabolism. Electron carriers such as nicotinamide adenine dinucleotide (NAD) and its phosphorylated form NADP mediate reduction or oxidation reactions via their own conversion between reduced…

The term “vitamin B1” indicates a family of molecules that includes thiamine, thiamine monophosphate and thiamine diphosphate (TDP). The latter is the most famous family member and plays a pivotal role in carbon metabolism. Thanks to an optimized detection protocol, Hofmann and colleagues have demonstrated…
