Plants use starch in leaf chloroplasts to fuel their growth and metabolism during the night. In Arabidopsis, nighttime starch degradation is tightly regulated; the degradation rate is linear and adjusts to both the availability of starch and length of night, so that most but not all the starch is used…

Photosynthesis is an attractive target for improving crop yields, and tailoring downstream photosynthesis-associated metabolism is a relatively unexplored path for achieving this. Chlorella ohadii is the fastest growing photosynthetic organism identified, has high photosynthetic rates, and can survive…

Lee et al. unravel a mitochondrial transporter responsible for selectively exporting citrate in exchange for malate. Plant Cell (2021) By Chun Pong Leea, Marlene Elsässerb, Philippe Fuchsb,c, Ricarda Fenskea, Markus Schwarzländerb, A. Harvey Millara aARC Centre of Excellence in Plant Energy Biology,…

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…
