Maybe a dumb question, but in a complete chromosome, is it normal to have base pairs after the telomeric repeats? Some of my T2T chromosomes sometimes have 300 bp after the repeats… Assembly artefacts?

Hidden Harvest is Excited to Be Part of Groundbreaking Cannabis Research! We’re thrilled to be part of the ongoing work at Université de Moncton, where some of our Hidden Harvest genetics are playing a key role in developing PM-resistant cannabis cultivars.

Never heard of a -80 that broke during regular working hours. Those things know when you’re not reachable. Still got there in time (-47) to make sure our precious pollen is kept safe. I would think it would lose viability quicker than bacterial cultures at room temperature.

Looking for someone that still has the installation disc (or equivalent) for the Perkin Elmer 2030 Workstation… I have an old Victor X3 for which the computer stopped working and I lost the CD!

Ok, this was way more impressive than I was thinking (and way more than the best I could capture with my phone)… #Eclipse2024

~20 years ago, I discovered a hybrid between two rust fungi. A paper just came out that investigated the frequency of these hybrids in WY and CO, and showed that some isolates could infect C. ribicola alternate host (Ribes spp.). @richamelin shorturl.at/hFM07

Question for the #MPMI crowd: if I have a ongoing infection on an N. benthamiana leaf, then agroinfiltrate an R gene recognizing the pathogen, will it kill the pathogen? Trigger a noticeable HR?

I remember there was some contamination between the genomes of Albugo laibachii and Golovinomyces but I don’t remember which way… Is this that many Albugo sequences are incorrectly labelled as Golovinomyces or the opposite (on NCBI)???

Are there any known examples of cereal Pm resistance genes being non-effective at higher temperature like we see for rust fungi? @gurcharn_brar @PietroSpanu @IzzySaur @lambros_f @stefan_kusch

Good news: proposal ranked 25/92. Bad news: not good enough for $$$. No worries. Projects are still going forward. Still, I'm glad I won't have time to think about it as I'm flying to @_SLU to give a seminar and participate to the thesis defence of Christian Benjamin Andersen!
