1/3 New preprint led by Shanshan Wang, in collaboration with the Timmermans lab.

Several groups have presented sc/snRNA-seq analyses of Arabidopsis leaves after bacterial infection before. Is there anything left to discover? Turns out: Yes.

😃

Super happy to share that I’ve passed my PhD defense! 🍾
It’s been an amazing journey doing my PhD in the Weigel World.
Huge thanks to my supervisor, Detlef @plantevolution.bsky.social , even with your crazy schedule, you always made time to guide me.
Couldn’t have done it without all your support!!!

Diagram of somatic TE insertions across the A. thaliana genome

In our latest @biorxiv-genomic.bsky.social preprint, we describe our approach to use PacBio HiFi reads to detect somatic TE transposition -- good enough to detect rare events that are present in only single cells. Led by Andrea Movilli.

Thanks, Eirik 😊

Large repeats are common in plant organellar genomes. Half of the A. thaliana mitogenomes we assembled have two large repeat pairs, while others have only one, where we identified two potential HGT events. Large repeats link to geography and cold traits.
Feedback welcome on bioRxiv, Email, etc.!

Phosphorylation‐dependent activation of the bHLH transcription factor ICE1/SCRM promotes polarization of the Arabidopsis zygote In Arabidopsis thaliana, the asymmetric cell division (ACD) of the zygote gives rise to the embryo proper and an extraembryonic suspensor, respectively. This process is controlled by the ERECTA-YODA...

Super excited to announce that our SCRM story is officially published!!! 🎉🎉🎉

How cool is that -- would not have guessed that the type of genetic incompatibility, hybrid necrosis, that we've studied for many years, is also the cause for graft incompatibility. I wonder whether it's a story of mismatched helper NLRs... @kamounlab.bsky.social

Disparity of cycad leaves dispels the living fossil metaphor - Communications Biology An analysis of leaf disparity through time in cycads shows that this group has a dynamic and expanding morphological diversity until the present, and thus does not fit the ‘living fossil’ hypothesis o...

last week my latest paper on #cycads came out.
The article deals with the idea of cycads as "living #fossils", but what does this mean exactly, and what did we actually test? A thread for #FossilFriday!

A spiral galaxy takes up almost the entire frame, from bottom left to top right. The circular-shaped galaxy is not seen perfectly face-on, but is slightly tilted. The galaxy has a bright light yellow central core that is surrounded by tightly wound spiral arms that are oriented counter clockwise. Beginning at the core and going to the right and then to the top are prominent, dark brown dust lanes. The other region forms an arc toward the bottom left, starting near the core at around 9 o’clock. The outer edges of the galaxy are where there are brighter blue areas filled with clusters of stars. Pink star clusters are found throughout, are most obvious toward the edges, and appear more clustered toward the middle-right edge and toward the bottom left corner. The background of space is black.

Asymmetry has never been so pleasing! Hubble’s near-infrared and visible-light view shows jostled dark brown dust lanes and a core knocked off center. Why? Galaxy M96 is part of a group of galaxies in a gravitational “tug of war.”
