Hard to make policymakers act when it's usually their greed and corruption that is the cause

How long is that? Be sure to check for potential off-targets with blast on genome!

Cool concept! How do you make it reproducible between batches if you need fresh soil isolate (I'm assuming)? I'm guessing if you split the soil into a few different tubes then let that sit for a few weeks the microbiota might start looking different just by chance🤔 Also would it work for syncoms?

Our latest work is out! We set out to see if we could recreate soil-nurturing plant growth in vitro. The plants looked happy and we see microbiome-induced cell-type-specific responses! A modest step but a fun challenge 😁

My favorite nucleus stain

Also I just learned that the dye is from Höchst outside Frankfurt, not in fact Austria where this is. But the sign is blue!

Using long hairpins too for my research right now ☺️ My strat for doing it in Arabidopsis is cloning it with golden gate and putting fluorescent seed as marker. Unique overhangs works best for assembly, doing same overhangs for all fragments (to make inverts) had pretty crap cloning success.

Your regular reminder that plant genomes are messy. Good luck getting your shortbread data to recapitulate this:

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.

Thanks Farid and @zmbp-tuebingen.bsky.social for inviting us from @mpi-bio-fml.bsky.social this year! I had a great time listening to the great talks from my peers at ZMBP and enjoyed the discussions and feedback about my work ☺️ see you again next year!

ZMBP @zmbp-tuebingen.bsky.social · 25d

Yesterday, we celebrated the 9th #ZMBP PhD Symposium, where our PhD students (and some from @mpi-bio-fml.bsky.social) presented their work as chalk talks, posters and longer talks. Thanks everyone for the scientific discussions on #plantscience!

Yeah there really is a lot of crap in most plasmids. Leftovers from agro and CaMV and random insertion events. Yuck.

Pluripotent, potatoes are a result of root apical meristem doing their thing, and plants can be regrown from the tubers. But the real answer is, depends on the plant.
