Anchoring Membranes in Cyanobacteria

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…

Transcriptome sequencing of a novel albino mutant of hexaploid sweetpotato (Plant Mol Biol Rep)

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…

Review. Chloroplast development in green plant tissues: The interplay between light, hormones, and transcriptional regulation (New Phytol.)

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…

Photosynthesis genes in the chloroplast help to direct species formation in Oenothera

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,…

Keeping an “i-on” chloroplast gene expression

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…

Radical Information - Daily Stress and When the Light is Just Too Strong…

Haber et al. developed an automated microplate system to continuously monitor levels of reactive oxygen species in planta. Plant Cell. https://doi.org/10.1093/plcell/koab068. By Zechariah Haber and Shilo Rosenwasser, The Robert H. Smith Institute of Plant Sciences and Genetics in Agriculture, The…

Structural insights into photosystem II assembly (Nature Plants)

Photosystem II is a multisubunit enzyme complex in the thylakoid membranes of plant, algae, and cyanobacteria. Here, Zebret et al. used cryo-electron microscopy to produce high-resolution structural information of the intermediate complexes involved in the biogenesis and assembly of photosystem II from…

Review: Improving crop yield and resilience through photosynthesis optimisation: panacea or pipe dream? (J. Exp. Bot.)

Has crop photosynthesis research been successful for increasing yields? This very crucial question is analyzed in a new review by Araus et al. The authors report that there has been no increase that can be described as a "quantum leap," but they discuss the merits of increasing leaf photosynthesis and…

Chlamydomonas keeps the rhythm going

By Patrice Salomé, Department of Chemistry and Biochemistry, UCLA, Los Angeles, CA  Salomé and Merchant analyze hundreds of RNA-seq samples in the single-cell green alga and discover vast co-expression potential and surprising residual synchronized expression across samples derived from cultures…
