Lipids build the membranes of all cells, but identifying their precise functions is extremely challenging. Here’s our attempt to change that: How to find and understand lipid-protein interactions, by Katelyn Cook & company. www.biorxiv.org/content/10.6...

FYI there is no "real" reason why Rome "fell." Its power waned for the usual, mundane reasons: widening gap between rich and poor, inability to maintain infrastructure, incompetent leadership, pointless wars, endless persecution of marginalized groups who performed vital labor, etc.

Plant–cyanobacterial symbioses: mutualism with emerging translational possibilities
Engineering rhizobial–plant nitrogen fixation in crops is a major goal in plant synthetic biology. We propose expanding efforts to plant–cyanobacterial symbioses as an alternative path. Targeting the ...

(1/16) Nearly two-thirds of ocean carbon fixation flows through a diverse organelle: the pyrenoid. Our new paper maps its 3D architecture in the alga Chlorella and identifies new proteins — expanding the toolkit to engineer this CO2-concentrating machine into crops🧵 #Pyrenoid #CCM #Photosynthesis

Excited to share our latest preprint on #PhycologyFriday. We map out the carbon fixation pathway for the first time in a multicellular alga, the green seaweed Ulva, and reveal a unique Rubisco-Linker interaction in the pyrenoid, a chloroplast condensate. Below I summarize some key points. #seaweeds

The algal pyrenoid fixes ~1/3 of global carbon, relying on a unique membrane-within-condensate architecture. How is this architecture built? We discovered that the protein MITH1 draws membranes into the pyrenoid condensate by promoting wetting! 🌿💧 www.biorxiv.org/content/10.6...
These little oases are entirely dependent on rainfall. The quillworts that live here have adapted by shortening their life cycle and shifting their growing season to winter and spring. Their spores mature in early summer as the pools dry out and plants enter dormancy.

This is a section of juvenile moss (Physcomitrium patens) tissue, called protonemata. The apical cells expand by tip-growth, while subapical cells sometimes divide to make lateral filaments. Cytosolic GFP is in green, and chlorophyll autofluorescence is in magenta. #microscopymonday #moss
