Increasing photosynthetic capacity appears to be a viable route towards increasing crop yields. An endogenous target identified for manipulation toward this goal is the cytochrome b6f (cyt b6f) complex that is located in the thylakoid membrane and which functions in both linear and cyclic electron transport,…

New reviews cover the hot topic of membrane and vesicle trafficking in plant immunity.  Gu et al. (Mol. Plant 10.1016/j.molp.2017.07.001) provide an overview of the two membrane trafficking pathways: the secretory pathway involved in movement of antimicrobials, defense proteins and cell wall components…

In 2016, Rangan et al. reported on “New evidence for grain specific C4 photosynthesis in wheat,” but later that year Busch and Farquhar responded with “Poor evidence for C4 photosynthesis in the wheat grain.” Now these two groups continue their arguments for and against wheat seed C4 photosynthesis,…

Protein-protein interactions are crucial to our understanding of biology but can be hard to detect. Trigg et al. developed a sophisticated yeast two-hybrid assay augmented with Cre recombinase (CrY2H-seq) to identify the Arabidopsis transcription factor protein-protein interactome.  In this method,…

Plants, green algae and cyanobacteria carry out oxygenic photosynthesis through the coordination of two photosystems, PSI and PSII. Many other photosynthetic prokaryotes use a single reaction center to carry out anoxygenic photosynthesis. Gisriel et al. describe the structure of a photosynthetic reaction…

Long et al. examined transcription factor complex formation in vivo in Arabidopsis roots using a technique that combines FRET (Förster Resonance Energy Transfer) and FLIM (Fluorescence Lifetime imaging Microscopy). Using this method, the authors were able to observe cell-type specific complex formation…
