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...

DARWIN REVIEW 🟢 Kenji Matsui reviews how and why plants came to smell green 🟢 Rapidly released from damaged cells, green leaf volatiles exemplify an evolutionary adaptation conserved across terrestrial plants, serving as essential defences and interplant signals shaping ecological interactions.
Fig. 3 (shortened, full legend in paper): Hypothetical mechanism of green leaf volatile (GLV) burst promotion by Arabidopsis lipoxygenase 2 (LOX2) activation. In intact cells (left), AtLOX2 exists as a soluble protein and does not exert its activity as it does not approach the membrane. Interaction of AtLOX2 with other proteins may be involved in the suppression of its activity. The Ca2+ concentrations in the vacuole and thylakoid lumen of intact cells are 0.2–5 and 15 mM, respectively, whereas stromal Ca2+ concentration is maintained low at 150 nM. Cell disruption disturbs the integrity of the vacuolar, plastid envelope, and thylakoid membranes, leading to Ca2+ leakage. Indeed, the Ca2+ concentration in completely disrupted Arabidopsis thaliana leaves was approximately 2.5 mM.
