Congrats @jeffgroh.bsky.social et al. Some avocado trees open female-phase flowers in the morning & then male in afternoon. Others show complementary pattern (m->f), to synchronize pollination of two types. Jeff show this to be a >45Mya polymorphism at a transcription factor across 100s of species.
Balanced polymorphism in a floral transcription factor underlies an ancient rhythm of daily sex alternation in avocado https://www.biorxiv.org/content/10.64898/2025.12.22.695989v1

I'm recruiting a postdoc for my group (based in beautiful Eugene, OR). Please get in touch if you're interested, esp if you'd like to chat at #ASHG25!
We'll primarily work at the intersection of statistical and population genetics, and we also have active projects related to the ethical and social implications of human genetics (ELSI). Please get in touch if that's a combination that sounds interesting to you!

I keep trying to get people to recognize that my having a PhD says a lot more about me being stubborn than me being smart.
PhDs aren't given to intelligent people.
They are earned by people who attempted something quite difficult, the creation of new subfield knowledge, and were both humbled and transformed by it.

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...
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.
