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.

Credit: Rob Tilley / MindenExcessive activation of the MUTE gene switch leads to unrestricted asymmetric cell divisions in the leaf surface of the succulent Kalanchoë laxiflora.
© Miro LäderachThe 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.
