What do u use to kill the agro? I use carb 500 mg/ul, or timetin 100, but when overgrown it's impossible to remove the agro.

What if the pollination causes changes? There's many examples of changes in pollination syndromes pre and post pollination, in other species....

Oh thats cool. I was curious if this variation is observed in the same plants.. If you play with conditions, you can also change flower size. Stress leads to smaller corolla's for example (soon to be published).
Map the trait, what do you think??

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.

So I am absolutely going to host a Flower Design symposium in 2030. This is a formal call for designers. We have @nickdesnoyer.bsky.social with his beautiful Arabidopsis roses, and I'm likely giving my life to my Alice Petunia...but we need more people. Where you at?!

Friday Flower 001: Mimulus lewisii ๐ŸŒธโœจ

Monkeyflowers are masterpieces of design with nectar-guide spots formed by an activatorโ€“inhibitor system of MYB transcription factors. These generate reactionโ€“diffusion patterns across the ventral petal.
