Very happy and proud to share our preprint on biorxiv where we describe two distinct mechanisms of nuclear and mitochondrial transfer RNA 3’ maturation. Thread below.

The move from a free-living environment to an endosymbiotic relationship has profound effects on bacterial function. This #UnsolvedMystery from John P McCutcheon &co explores how bacterial endosymbionts work with so few genes. #symbiosis plos.io/441F6Gk

Thrilled to "ExPOSE" our preprint! We present ExPOSE: a comprehensive toolkit to perform expansion microscopy in plant protoplasts. Great collaborative work with Sarah Pardi Lily O'Connor Nusinow Lab and the Advanced Bioimaging Lab! biorxiv.org/content/10.110…

Happy to share our new preprint, reviewing the expansion of the MutS gene family in plants. Feedback welcome! biorxiv.org/content/10.110…

Can free-living eukaryotes exist without mitochondria? In a new paper from my group led by Shelby, we show that the answer is probably yes! nature.com/articles/s4146…

Anna Karnkowska But M. exilis is a protist that is a commensalistic inhabitant of the gut of chinchillas. In this new paper we find a second case of complete mitochondrial loss in Skoliomonas litria, a protist isolated from alkaline lake sediments by Yana Eglit Psi Wavefunction !

The Hagler lab is hiring a research technician/assistant!!! Please consider applying if you are interested in RNA structure, RNA-protein interactions, and drug discovery. tamus.wd1.myworkdayjobs.com/en-US/TAMU_Ext…

The mitochondrial protein synthesis machinery in 4D (gorgeous 3D structure plus motion over time) This is how mitochondria synthesize parts of the life-giving electron transport chain

4) The scientific method also applies to computational results: proper controls and negating all alternative hypotheses are just as important in computational biology as in bench experiments.

My favourite discovery ever has just come online. Can I please tell you about some seriously wacky molecular biology? The story starts with a reverse transcriptase that SOMEHOW defends bacteria from viruses. (👇 I recommend sound ON for the video 🎹) 1/

Excited to see our work out in preprint form! Not all mitochondria carry mtDNA in plants- so we asked: is there a link between dynamics, intermitochondrial connectivity and presence/absence of DNA- and we show- yes! 🤓🌱

Happy to see The Plant Cell include this text in their author guidelines. I fully agree!

Super excited to share our latest work on the native in-cell organization of the mitochondrial respiratory chain 🥳 Using cryo-electron tomography🔬, we show how the respiratory complexes (and other complexes) are organized inside native mitochondria!  biorxiv.org/content/10.110…

Check out our paper! We identify a population of retinal progenitors that are maintained late in human retinal development, and give rise to both first- and last-born cell types in the retina, condensing 100 days of retinal development into a small region at the retinal margin!

A new fascinating symbiosis in plankton unveiled by imaging and physiology: Hijacking and Integration of Algal Plastids and Mitochondria in a Polar Planktonic Host. New preprint of the team led by AR with Omaya Dudin🍉¦ 🦠¦🔬¦ Elisabeth Hehenberger Florian Jug groups biorxiv.org/content/10.110…

Collaborative work of slavica pavlovic djuranovic, Yaser Hashem, Jovanovic Lab and Sergej Djuranovic - a new method to isolate ribosomes and translational material in minutes. We show multiple usage of our RAPPL method in biochemical and structural assays with ribosomes. Please be free to contact

Check out our new preprint on plant🌱mitoribosome! We captured it in action, translating mRNA, and combining cryo-EM and Nanopore sequencing, identified key rRNA modifications. Plus we delve into a late-stage maturation step of the small subunit. 📖:biorxiv.org/content/10.110…
