Glad to share a little bit of plant science and P. syringae to the @cmdi.bsky.social group seminar at the Georgia Institute of Technology 🌱

Cysteine-rich receptor-like kinases mediate Wall Teichoic Acid perception in Arabidopsis Plants and animals detect microbe-associated molecular patterns (MAMPs) to initiate defense responses. Both lineages employ pattern recognition receptors (PRRs), yet plant mechanisms for sensing Gram-...

Gram-positive bacterial MAMP sensed by a plant cysteine rich receptor kinase. I've been waiting for this preprint to drop. Nice story!

It was truly a convenient way to access reporter expression, protein-protein interaction, and so much more in plants without microscope or something fancy!

Lucky enough to have a chance to try out this tool in Nbemthi and Arabidopsis with the REEU summer intern in our lab last year!

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.

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.

Our review on disease resistance gene diversity in Triticeae is finally online 🌾🌾! Gained so many insights writing it with Yinghui Li & Liubov Govta and from the guidance of gittacoaker.bsky.social & Tzion Fahima. Fascinated by plant resistance gene diversity—excited to share!
