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.

Understanding how evolution shapes genetic networks to create new developmental forms is a central question in biology. Flowering shoot (inflorescence) architecture varies significantly across plant f...

Developmental timing in plants is tightly regulated at the whole-organism scale, from germination to flowering. Less is known about when and how local transitions are temporally regulated. Not every ...
