Plants must adjust to varying levels of light in order to optimize photosynthetic rates; too little electron transport and plants will incur an energetic penalty, while excessive excitation of photosystem I leads to photodamage. During high light conditions, the increase in DpH acts as a brake on electron…

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…

Despite a large variation in leaf morphology, laminar leaf anatomy is largely conserved, comprising two developmentally distinct mesophyll tissues, the palisade and spongy mesophyll. Spongy mesophyll cells along with intercellular spaces form an interconnected network to maximize the surface area for…

Ostermeier et al. introduce AncM, a new factor for structuring the photosynthetic membrane system in cyanobacteria. Plant Cell https://doi.org/10.1093/plcell/koab253 By Matthias Ostermeier, Steffen Heinz and Jörg Nickelsen at Molecular Plant Science at LMU Munich Background: Cyanobacteria are…

Albino plants lack chlorophyll, which means that they cannot photosynthesize. These kinds of plant are unique and can offer information as to the molecular mechanism of chlorophyll degradation and photosynthesis in plants. Here, Arisha et al. explored the differences in gene expression patterns of seedling…

Chloroplasts are indispensable for plant growth and physiological performance; not only for photosynthesis but also for many biochemical processes. Due to the endosymbiont origin of the chloroplast, chloroplast development requires sophisticated machinery to relay the signals between the nuclear and…

Zupok et al. demonstrate that photosynthesis genes encoded on the chloroplast genome can establish hybridization barriers. Plant Cell. (2021)  https://doi.org/10.1093/plcell/koab155 By Arkadiusz Zupok, Danijela Kozul and Stephan Greiner, Max Planck Institute of Molecular Plant Physiology, Potsdam/Golm,…

DeTar et al. examined whether disruption of ion homeostasis affects plastid gene expression and chloroplast development. Rachael Ann DeTar and Hans-Henning Kunz both at School of Biological Sciences at Washington State University & Plant Biochemistry at LMU Munich Background: Proteins that…
