Please share! I'm looking for a postdoc. The position is to lead one of the following projects: 1) regulation of plant specialized metabolism by cell fate, or 2) foliar embryogenesis in the succulent plant Kalanchoe. Learn more abt projects: cxli233.github.io/cxLi_lab/res...
cxli233.github.io
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.

Our current carbon economy relies on fossil fuels, from which we isolate small organic molecules to produce medicines, plastics, cosmetic, or other chemicals that we use everyday. However, sustainability requires a more biomass-based carbon economy, where we engineer plants to produce precursor molecules, which can then be assembled to desired chemicals that we use daily. Plants have evolved an amazing diversity of metabolites, but these metabolites are not produced in every cell of the plant. Therefore, it is essential to understand how plants can express different metabolic pathways across different organs, tissues, and even cell types. We are interested in the following questions: How are metabolic pathways (especially specialized metabolism) controlled by cell fate? How can we reprogram plant cell fates for biomanufacturing? How can we toggle between differentiated cell states for metabolic engineering and totipotent cell state for genetic engineering?
