Here's 123 new bryophyte genomes for you!
Apparently, bryophytes time and again include microbial genes in their genomic repertoire, and occupy a langer gene space than vascular plants.

Bryophytes hold a larger gene family space than vascular plants - Nature Genetics

A super-pangenome analysis incorporating 123 newly sequenced bryophyte genomes reveals that bryophytes exhibit a larger number of unique and lineage-specific gene families than vascular plants.

Which fungal 🍄 molecules cause zombie 🧟‍♀️ ant 🐜 behaviors? @williamycete.bsky.social has begun to answer this question! He found a peptide that binds to scramblase and affects important odor-dependent behaviors in ants. Spoiler: worms 🪱 played a key role in this research 🧐 doi.org/10.1101/2025...

Finally, I also want to highlight our other review on cortex, this one is specifically about Poaceae and more about the physiological roles of the different cortex modifications:

Very cool - and yes, I would be interested in reading that!

Kaisa Kajala @kaisakajala.bsky.social · 20d

Great questions! I personally don’t like the molecular signatures for defining cell types as we don’t know how well they hold across evolution. If a similar looking/functioning cell types convergently evolve (with different grn), are they then different cell types?

Kaisa Kajala @kaisakajala.bsky.social · 22d

Starting in 3h or so - we will be discussing why and how we should be defining cell types and states - I expect really stimulating conversation and important suggestions for how to (not) use the terminology!

This might be one of the simplest images I captured, but very fascinating nonetheless, as it shows how tight the cytoplasm in a plant cell is. The cytosol and all other organelles are squished between the plasma membrane (magenta) and the central vacuole (its membrane is green)
#MicroscopyMonday

The image shows one straight magenta line and, close to it, another wavy green line.

A de novo-originated gene drives rose scent diversification

Genomic analysis of more than 100 Rosa species uncovers a multi-step process for the de novo origination of SCREP, a taxon-restricted gene specific to the Rosa genus, highlighting its function in modulating eugenol biosynthesis and driving rose scent diversification.

these are all real DAP-seq peaks!

specifically, peaks in the promoter of SWEET11 (a sugar transport gene) and its orthologs across 10 plant species

the darker colored peaks are binding sites for transcription factors that have maintained regulation of SWEET11 across 100+M years of plant evolution
