Thrilled to share our latest short technical paper in PCP!
We propose an alternative leaf-level gas exchange measurement method with petiole-cut leaves and whole plant chamber, enabling the measurements even with the small Arabidopsis plants.🌱

we find evidence that mistranslation in wild-type plants varies under stress conditions. This suggests that optimization of protein synthesis may improve plant stress tolerance. Moreover, the initial discovery of a hypermistranslating Arabidopsis mutant will benefit

mistranslation was unknown. We isolated a Q➡️E hypermistranslating Arabidopsis mutant and show that plant cells are highly tolerant towards Q➡️E mistranslation in mitochondrial- and plastid-expressed proteins and even incorporate Q➡️E altered peptides into the photosynthetic machinery. Interestingly,

that gene expression works close to perfection, especially protein synthesis is a messy business. Bacteria use protein mistranslation since increased proteome plasticity can aid survival under stress conditions. The relationship of plant cells and their bacterial-type organelles towards protein

Please read here the summary of our news on DOG1 and its signaling pathway via AHG1 and AFPs in Arabidopsis 🌱seeds. www.uni-muenster.de/news/view.ph... @uni-muenster.de #seeds #plants @seedbarrett.bsky.social @ifink-lab.bsky.social

DOG1 controls dormancy independently of ABA core signaling kinases regulation by preventing AFP dephosphorylation through AHG1 DOG1’s autonomous signaling pathway allows seeds to regulate dormancy and stress traits independently.

Our labrodog also highly recommends reading about DOG1 because it’s important for seed storage, agriculture and our food! www.science.org/doi/10.1126/... #plantscience #seeds

And most important: independent of ABA-dependent SnRK2 activity!

DOG1 controls dormancy independently of ABA core signaling kinases regulation by preventing AFP dephosphorylation through AHG1 DOG1’s autonomous signaling pathway allows seeds to regulate dormancy and stress traits independently.

Our manuscript on the DOG1 dormancy pathway is out! 🥳 It started with a phosphoproteome when working @mpipz.bsky.social and 10 years of hard work @uni-muenster.de from Guillaume Nee with Thorben Krüger and more to prove that AFPs are target! #proteomics #seed www.science.org/doi/10.1126/...

We propose that the molecular separation of the DOG1-PP2C module from the regulation of SnRK2 activity keeps seed ABA signaling primed independently of the dormancy level. This allows non-dormant seeds to quickly reinduce ABA responses and arrest germination upon sensing stress.

Very happy that our story on dormancy control by DOG1-PP2C is now published in Science Advances. We found that DOG1 prevents the activation of AFPs by AHG1. This is the result of a great team effort led by Guillaume Née. Summary of key findings below🧵 www.science.org/doi/10.1126/... @science.org
