Plant cells are totipotent, meaning individual cells have the potential to develop into a full organism, a property unique to the zygote for animals. However, in most species for most cells, plant cells are not spontaneously totipotent, since they must be treated with specific hormone combinations to unlock their totipotency. Species within the Kalanchoe genus is unique as they spontaneously develop foliar embryos that are fully realized plantlets with shoot and root from notches along the edges of leaves. We speculate that the progenitor cells that give rise to these foliar embryos are totipotent, and we are using single cell techniques to identify & characterize them. In addition to being a fundamental process for plant biology, we foresee unlocking totipotency has many biotechnological applications, such as faciliating genetic transformation and the development of synthetic organs of biomanufacturing.

The evolution of plants – photosynthetic eukaryotes resulting from the endosymbiosis of a cyanobacterium and a non-photosynthetic host cell – transformed the earth system by reducing the amount of CO…

Europe’s first field trial of gene-edited vines began in northern Italy on 30 September 2024. Developed by EdiVite, a spinoff from the University of Verona, these Chardonnay vines have undergone gene ...
