ApE users: Does anyone know a work-around for opening the .ab1 files from some whole-plasmid sequencers? ApE can open files from @plasmidsaurus.bsky.social but not two others. (Other apps can open them all, but can't align them like ApE.)

Czechia has been pronounced as “Chechnya” by three people at NBC4-LA in their sports coverage. I’m thinking the last guy was finally corrected as he said “Czech Republic” when they returned to him. Ooof.

Happy to announce our study that has just been published from work done during my PhD at the University of Bristol working in Prof. Jill Harrison's lab. It's about WOX genes and sporophyte development in the model moss, Physcomitrium patens. Take a look 🧵👇

We know a lot about how roots grow but far less about why they stop, decline and die. In our recent @theplantcell.bsky.social review, Feng Qin connects the biology of root growth and root aging, highlighting opportunities to extend root function, enhance crop productivity, and increase soil carbon.

this is not my ideal way of seeing my lab published in Science magazine, but, here we are. Roger is well known as a devoted life-long plant scientist, but he is also an incredible human being who shows constant kindness and encouragement to everyone around him. this is simply not fair.

I hope none of the former Estelle lab members wanted to rescue their old boxes of seeds and plasmids! Also, I learned today that metal paper clips cannot go in biohazard waste, so I'm slightly annoyed with the many large boxes in which every envelope was paper clipped. Luckily, have help.

It looks like there will be an open postdoc position in my lab soon. I'll be looking for someone with substantial wet-lab experience in microbiology / microbial ecology / evolution / physiology. If everything goes well, an ad will be coming. But if you know someone, ask them to reach out already.

The last gel in the long history of the Estelle lab just became the penultimate gel when I got distracted and ran it too far.

I'm going through and updating my moss genes' GeneIDs to the Ppv7 annotations. After all of the gaps in v3 and the occasional sequence jumbles in v6, v7 is perfect as far as I can tell! I only wish it was more easily available.

Ugh, whole-plasmid sequencing was supposed to SAVE time. We've been burned by an oddly optimistic base caller. Almost two-thirds of the reads had a GGA → TGA nonsense mutation, but it called it GGA. Of course, we did our experiment with a TGA colony. @genewiz.bsky.social

Bittersweet milestone: I think I wrapped up my last ever set of moss DNA preps/genotyping PCR. Nice note to end on; I got a great efficiency—44% of the transformants appear to have clean deletions of the entire gene that was targeted (5.9 & 6.8 kb deletions).
