Apomixis in Boechera isn't a quirk—it’s driven by fragile genomic sites, B chromosomes, and chromosome fissions.

Key takeaway: Evolution is reusing these fragile regions repeatedly to trigger apomixis. Not just dosage, but structural evolution! #PlantSci #Evolution #Genetics #PAG33

Legumes usually fix nitrogen in their roots, but Sesbania rostrata does it in the stem. Haofei Luo used EMS to find that ARP1 is a key transcription factor, and when overexpressed, can induce stem nodule-like structures in a relates species. #PlantSci #Legumes #Symbiosis #PAG33

For example, you shouldn't use a splice-aware RNA-Seq aligner like STAR on reads from a prokaryotic organism. 🧬 🖥️ #PAG33

I think this is why it can be challenging to teach bioinformatics. There is so much knowledge that needs to be taught!

What other examples can you think of?

Bioinformatics rests on three pillars of knowledge: Biology, Sequencing Technology and Software. Not understanding the assumptions and limitations of these pillars as they relate to your project will reduce your ability to explore your data. 🧬 🖥️ #PAG33

Agata Daszkowska-Golec highlights a "genetic flip" where removing two components of the cap-binding complex (CBC) actually creates hormone insensitivity though single mutants are highly sensitive. CBC loss disturbs the spliceosome and interacts with SERRATE (SE) to alter mRNA metabolism. #PAG33

Kevin Cox presented Expansion Microscopy: using a swellable hydrogel to enlarge cells physically moving cellular structures apart, allowing nanoscale imaging on a standard light microscope. I wonder if this can translate to better chromosome squashes? #Microscopy #Jim_Birchler #PAG33

In a global first, Uganda’s Ministry of Health, the World Health Organization (WHO) and other partners today launched a first-ever vaccine trial for Ebola from the Sudan species of the virus, and at an unprecedented speed for a randomized vaccine trial in an emergency.🧵

RIP blood brain barrier & brain trauma grants

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

The soybean cyst nematode genomics database has been updated as of last night. SCNBase.org now has all 9 early release H. glycines genomes and annotations. All files are downloadable and accessible through BLAST, feature search, and Jbrowse. The pan-genome paper is coming soon! #science #genomics

Turkeys have 80 chromosomes. Humans have 46. We don't know the biological significance of the chromosome numbers. All we know is changing the number changes the biology.

Unlike XX/XY in Humans, Birds have ZZ/ZW system. There's more, males are homogametic ZZ, and females are heterogametic ZW.

Whales are more closely related to cows than cows are to horses
