It's not just human relationships that may require a chaperone to prevent inappropriate interactions. Numerous proteins in organisms from Escherichia coli to us, especially hydrophobic membrane proteins, also require chaperones in aqueous environments to prevent inappropriate interactions such as aggregation…

The gardeners among us know that direct sunlight is a prerequisite to obtain full-sized, bright red tomato  (Solanum lycopersicum) fruits. Indeed, light increases the accumulation of yellow and red carotenoid pigments, particularly lycopene, in ripe tomato fruits while it also boosts chlorophyll levels…

The endoplasmic reticulum (ER) is an organelle that is vital for many cellular processes such as protein and lipid synthesis, calcium signaling, detoxification, and movement of other organelles. It forms an intricate meshwork in the cell cortex that is comprised of highly dynamic interconnected tubules…

Small signaling peptides are cleaved from precursor proteins by the action of proteases and are also subject to other post-translational modifications. Subtilases (SBT) are mostly extracellular proteases, but SBT6.1 is membrane-localized at the Golgi and plasma membranes. Furthermore, it has been shown…

Maize has provided some fascinating mutants and developmental insights, but its genomic complexity has made it more difficult (for example as compared to rice) to identify agronomically important genes. Liu et al. describe a new high-throughput method to integrate forward- and reverse-genetics to identify…

Sun et al. reveal the subcellular organization of photosystem biogenesis in Chlamydomonas. Plant Cell https://doi.org/10.1105/tpc.19.00263 by Melissa Valente-Paterno, Yi Sun and William Zerges. Department of Biology, Concordia University.  Background: Cells localize intracellular processes to…

Sun et al. showed that OR interacts with TCP14 in the nucleus of dark-germinated seedlings and reduces chlorophyll biosynthesis, thylakoid membrane development and expression of EARLY LIGHT-INDUCIBLE PROTEINS, and that subsequent illumination relieves this repression.
