Reviews: Membrane and vesicle trafficking in plant immunity and beyond ($)
Blog, Plant Science Research Weekly, Research, Research BlogNew reviews cover the hot topic of membrane and vesicle trafficking in plant immunity. Gu et al. (Mol. Plant 10.1016/j.molp.2017.07.001) provide an overview of the two membrane trafficking pathways: the secretory pathway involved in movement of antimicrobials, defense proteins and cell wall components…
Letters to the Editor: Does C4 photosynthesis occur in wheat seeds?
Blog, Plant Science Research Weekly, Research, Research BlogIn 2016, Rangan et al. reported on “New evidence for grain specific C4 photosynthesis in wheat,” but later that year Busch and Farquhar responded with “Poor evidence for C4 photosynthesis in the wheat grain.” Now these two groups continue their arguments for and against wheat seed C4 photosynthesis,…
CrY2H-seq: a massively multiplexed assay for deep-coverage interactome mapping ($)
Blog, Plant Science Research Weekly, Research, Research BlogProtein-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,…
Structure of a symmetric photosynthetic reaction center–photosystem ($)
Blog, Plant Science Research Weekly, Research, Research BlogPlants, green algae and cyanobacteria carry out oxygenic photosynthesis through the coordination of two photosystems, PSI and PSII. Many other photosynthetic prokaryotes use a single reaction center to carry out anoxygenic photosynthesis. Gisriel et al. describe the structure of a photosynthetic reaction…
In vivo FRET–FLIM reveals cell-type-specific protein interactions in Arabidopsis roots ($)
Blog, Plant Science Research Weekly, Research, Research BlogLong 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…
Metabolic engineering of anthocyanin and betalain pigments for health and aesthetics: Purple rice, blue chrysanthemums and violet tomatoes
Blog, Plant Science Research Weekly, Research, Research BlogPigment engineering was featured in three recent papers. Anthocyanins are blue pigments valued for their antioxidant health benefits and for their beauty, but their biosynthesis and chemistry is complex. Noda et al. introduced two genes to produce blue anthocyanins in chrysanthemum petals (Sci Advances…
Rhamnose-containing cell wall polymers suppress helical plant growth independently of microtubule orientation
Blog, Plant Science Research Weekly, Research, Research BlogSaffer et al. identified an Arabidpsis mutant with swirled petals and with petal epidermal cells that show a left-handed (but never right-handed) twist. They mapped the mutation to the RHAMNOSE BIOSYNTHESIS1 (RHM1) gene, which is most highly expressed in petal epidermal cells and encodes an enzyme that…
