Who at #botany2026 is thinking about which talks to see tomorrow? Maybe I humbly recommend our talk on Physalis phylogenomics where we ask the question, why are there so many tomatillo species 50 million years after a (famous to Solanologists) bottleneck? Tomorrow 1:30pm in San Ignacio!

We identified a novel location for acylsugars, on the fruit surface, widely distributed across the Physalis genus. Paves the way for understanding the cell types and regulation responsible to fruit-surface localized acylsugars in collab with @iochromaland.bsky.social www.biorxiv.org/content/10.1...

A new phylogeny and phylogenetic classification for the nightshades 🍅🌶🍆 Thirteen years after the previous family phylogeny, we expanded the sampling, reaching 1474 species and resulting in a new rank-free classification for Solanaceae dx.doi.org/10.1002/tax....

The new bee documentary is out today in Disney+. Our buzzing bees did make the cut at the end! It is really nice to see the clip of how bees use previously collected nectar to pack pollen even in nectarless flowers! There are lots of other cool things in this two-part film!

And now it is out! Even if you haven't been sweating how old tomatoes are, click for some lovely time trees decorated with plant fossils! (or if you're thinking about doing a TED analysis yourself and want to see how we pulled it off :) academic.oup.com/aob/advance-...

The seed fossil record of Solanaceae revisited is out! Using morphometrics and micro-CT data from 110 fossils and 354 extant taxa, we described 6 new genera and 6 new species, doubling fossil diversity for the nightshades! 🔗 doi.org/10.1002/tax.... @iochromaland.bsky.social

@sandyknapp.bsky.social opens the #SOLRUB2025 meeting talking about how wonderful are #Solanaceae species. New dating results are coming out soon. The family is older that we thought. Almost 90 MY. She closes her presentation talking about the importance of community.
