Our work on chromatin evolution in brown algae is now published in @natecoevo.nature.com! We show that developmentally complex brown algae evolved without epigenetic silencing pathways long thought universal, underscoring why non-model lineages are important to study. www.nature.com/articles/s41...

Also many thanks to @claudiakohler11.bsky.social and @mpi-mp-potsdam.bsky.social for supporting this little project of making seed phenotyping less user-biased.

Thanks to @newphyt.bsky.social for a straightforward review and publication process and of course to the reviewers for constructive feedback to improve the manuscript!

First publication of the year! We set up an image-based quantification of seed phenotypes (here Arabidopsis thaliana). It comes together with a random forest classifier for our favorite phenotype, seed abortion.

Preprint alert! It is my great pleasure to announce the first manuscript from the lab, a story that started @gmivienna.bsky.social and was mainly accomplished by the intrepid @gesahoffmann.bsky.social at @mpi-mp-potsdam.bsky.social. A brief thread with our findings www.biorxiv.org/content/10.1...

AGO5 restricts virus vertical transmission in plant gametophytes
The propagation of a viral infection from a host parent to its progeny is known as vertical transmission, or seed transmission in plants. It allows viral infections to rapidly spread locally via polle...

It was wonderful to have Bijun with us @mpi-mp-potsdam.bsky.social & @incavirus.bsky.social to finally "use our microscope to its full potential" as our core-facility put it! 🔬 Congrats to all, esp. @bijuntang.bsky.social and @xanderjones.bsky.social ! Super happy to be a part of this great story!

Huge thanks to everyone involved! This has been a fun project—useful for our own experiments and, hopefully, valuable for others as well!

Samplify can also provide detailed parameters of your seed population—size, color, shape, and more. For further information, check out our preprint.

Naturally, this reduces user bias—here, mostly my own. So we built a full framework for training models and annotating images, making it easy for anyone to create their own seed classifier.

This approach to quantifying the triploid block worked remarkably well, achieving near-perfect classification—closely matching human annotations of seed abortion:

Luckily, I already had thousands of manually scored seed images— over 13,000 seeds in total. This gave us a solid base to train a random forest classifier, which our bioinformatician used to achieve reliable seed classification.

In a great collaboration with our institute’s bioinformatics group, we developed "Samplify"—a tool that blends classic image segmentation with the transformer-based Segment Anything Model (SAM) to accurately count seeds, even when they touch or cluster, aligning almost perfectly with manual counting

Heinrich Bente @hebente.bsky.social · 27/09/2025
We always dreamed of automating seed phenotyping to save time and reduce user bias. But Arabidopsis seeds are tiny and often cluster, making analysis tricky—traditional imaging methods usually just excluded those clusters.

Heinrich Bente @hebente.bsky.social · 27/09/2025
Quantification of these aborted seeds was traditionally done manually, i.e., by taking a picture and counting how many normal, abnormal, and totally aborted seeds were present in a given image. The problem was always the huge variation between different people doing the counting.

Our lab has a keen interest in hybridization barriers, such as those that occur in Arabidopsis when parents of different ploidy are crossed — a phenomenon often referred to as the "triploid block." Normal seeds appear light brown, plump, and healthy, whereas seeds from interploidy crosses do not.
