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.

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.

Our first study on how the leaf succulent Kalanchoë laxiflora makes stomatal subsidiary cells is finally peer-reviewed & out - and it made the cover! 🌵 🧬 🔬 doi.org/10.1126/scia... Despite 150 years of evolution, grasses and Crassulacean succulents use the SAME gene to make subsidiary cells! 🤯

ONLINE COVER: Leaves of Kalanchoe thyrsiflora, a member of the Crassulaceae family of succulents also containing Kalanchoë laxiflora. Stomata, otherwise known as plants’ breathing pores, allow gas exchange between plants and the atmosphere, but little is known about how succulent stomata are formed or move. Cheng et al.’s investigation into K. laxiflora revealed that subsidiary cells can support the opening and closing of stomata and that the transcription factor MUTE, which drives stomatal development, also facilitates additional rounds of asymmetric division needed to generate subsidiary cells. Their work provides insight into succulent development and could be applied in agricultural contexts to engineer water conservation strategies.

Excessive activation of the MUTE gene switch leads to unrestricted asymmetric cell divisions in the leaf surface of the succulent Kalanchoë laxiflora.

The MUTE gene switch is active in all cells of the developing stomata. Gene activity is visible through a weak signal (in blue) in the future helper cells and a strong signal (in green) in the mother cell of the guard cells.
