📢 New publication 'Evolutionary history of sex and accessory chromosomes in #hornworts' by John Bowman and Jonathan Levins in @newphyt.bsky.social 🧪 doi.org/10.1111/nph....

It’s hard to believe our summer undergraduate researchers are wrapping up in just a few weeks! This summer of science has flown by. Catch up on their adventures in the lab, out in the field, around Ithaca, and beyond!

A little belated but I've started a faculty position at Ecology, Evolution and Marine Biology department at @ucsantabarbara.bsky.social. I'm absolutely stoked! I'll be recruiting at all levels and will be at #Botany2025 Reach out! www.martinezgomezlab.com

This seems to work really well! Improved a draft genome with N50=0.5 Mb (flye 2.9.4/hifiasm-0.19.8), increased to N50=5 Mb (11 Mb after removing all the repetitive element contigs)

Preprint on hifiasm Nanopore-only assembly. Led by Haoyu Cheng: www.biorxiv.org/content/10.1...

🎉 Great news! The paper ‘Distinct patterns of genome size evolution in each bryophyte lineage are not correlated with whole genome duplication’ in @annbot.bsky.social by Nikisha Patel and co-authors is now #free for a limited time 🧵(1/8) 👉 doi.org/pcjr @mossplants.bsky.social #AoBpapers

The reviews are in, this was the best Quillwort Conference ever! Thanks so much to our speakers: Gemma Milly Lisa George David Wickell @wickellomics.bsky.social Megan Nibbelink @megantheebotanist.bsky.social Jacob Suissa John Evans

(2/2) Giant sex chromosomes were discovered in Silene latifolia more than 100 years ago. Two papers back to back now show the sequence of the 550 Mbp Silene Y chromosome helping to understand sex determination www.science.org/doi/10.1126/... www.science.org/doi/10.1126/... #plantscience

I am very proud of UMN Duluth undergrad Isabel Smalley, whose summer REU project led to co-authorship on her first paper, now out in Nature Plants! 🎉

Second paper of the year led by Peter Schafran from @fernway.bsky.social lab (Cornell University). Again hornworts rock !! www.nature.com/articles/s41...

First paper of the year, led by Tanner Robison from @fernway.bsky.social lab (Cornell University!). Hornworts rock!! www.nature.com/articles/s41...

Paper #2 - we generated 10 new chr-level genomes for hornworts covering all families and most genera. Also the first look into their U/V sex chromosomes! 3/4 www.nature.com/articles/s41...

Two new #hornwort papers from our group out in Nature Plants @natureplants.bsky.social today - a great way to celebrate the new year! 1/4

One thing yinz should all know is whenever you write a title of the form <Catchy Phrase> [colon] <Description Of What The Paper is About> I reserve the right to decide whether or not the phrase following the colon is interesting or informative enough to be worth the aesthetic cost to my bibliography
