It's 30 years to the day since the first GM crop product went on sale in the UK. To celebrate this milestone, here's a pic of my original tin with our new GM tomatoes engineered to accumulate omega-3 fish oils in the fruit. In collaboration with @johninnescentre.bsky.social & Susana Silvestre.

8/ 📣 Help us spread the word!
Please repost/share this thread and tag colleagues working on mitochondria, chloroplasts, protists, parasites, evolution, metabolism, or synthetic biology.

4/
• Synthetic & High-Throughput Organellar Biology

🔬 Want to give a talk?
Each session has talk slots selected from submitted abstracts.
⏰ Program finalization: March 21 → if you want to be considered, submit your abstract now.

3/ Sessions on:
• Origins & Evolution of Organelles (Keynote)
• Organelle Gene Expression
• Protein Import, Sorting & Assembly
• Structure & Function of Organelle Complexes
• Organelle Metabolism
• Responses to Fluctuating Environments
• Proteostasis & Biogenesis
• Non-Canonical & Novel Organelles

2/ What makes this GRC special?
The sheer breadth of biology. From classic endosymbiotic organelles to:
🦠 apicoplasts of malaria parasites
🐌 kleptoplasts in sea slugs
🧪 the recently described nitroplast
➕ deep cell biology, physiology, metabolism, evolution, and synthetic organellar biology

1/ Energy-Transducing Organelles at the Nexus of Evolutionary Biology & Synthetic Engineering
This GRC is deliberately cross-kingdom and cross-disciplinary: from biomedical to plant science, from mammals to protists. Care about mitochondria, chloroplasts, or anything in between? This is for you!

🧬⚡ Call for abstracts & participants | GRC 2026 ⚡🧬

Together with Vamsi Mootha, I’m chairing the 2026 Gordon Research Conference on Mitochondria & Chloroplasts (July 19 - 24, 2026). We’d love to see your application.

Gentechnik wird zur gezielten Änderung des Erbguts eingesetzt – z.B., um genetische Defekte zu korrigieren. Eine bekannte Methode ist die Genschere, auch CRISPR/Cas genannt. Sie wird u.a. bei Pflanzen angewendet, um Krankheitsresistenzen, höhere Erträge oder bessere Klimaanpassungen zu erzielen. 1/4

Likely Brassicaceae lost the ability to evolve C4.
This review in the journal Plant Biology, the journal of the German Society for Plant Sciences @plantsciencedbg.bsky.social, summarizes the current knowledge on Cleomaceae. #PlantScience

Cleomaceae: diversity and potential of a model family for studies on the evolution of photosynthesis The Cleomaceae family integrates floral diversity, physiological plasticity, and the evolution of C4 photosynthesis, serving as an important model to investigate plant adaptation and evolutionary inn...

Cleomaceae are the sister group to the Brassicaceae. In contrast to the Brassicaceae, they contain true C4 photosynthetic species. This indicates that the genetic capacity to evolve C4 is ancestral to the split of Brassicaceae and Cleomaceae.

Ganz unabhängig davon, wie man zu den Neuen Genomischen Techniken (NGTs) steht, gibt es natürlich einfach grundlegende Fakten, die man nicht einfach ingnorieren kann.

"Plant single cell RNAseq workshop: From current technologies to data analyses"  Saclay Plant Sciences Summer School, June 28 - July 3, 2026 – Versailles (France) This Summer school is organized by the Saclay Plant Sciences (SPS) network, one of the largest European plant sciences communities.   scRNAseq approaches have revolutionized the way biologists approach their research subjects, by making it possible to dissect molecular mechanisms at the single-cell level. But although technological developments have recently made these approaches more accessible, their expensive use still requires significant technical training, including the good conception of experimental designs, the preparation of samples as well as their bioinformatics analyses. In addition, different protocols and various bioinformatics and statistical analyzes are available, and it can be difficult to choose the most relevant ones for the biological question at hand.   Over five days, the SPS Summer School 2026 will cover all the stages of a scRNAseq project in plants. Through a combination of lectures and practical work, the many specific features of plant models will be highlighted by experts from the Saclay Plant Sciences network (CNRS and INRAE), the ViB in Ghent and the Pasteur Institute. After this international school, participants will: –    Have an overview of the different scRNAseq technologies and understand their pros and cons. –    Be able to design experiments depending on the biological question.  –    Be trained on sample preparation techniques for single cell and single nuclei –    Understand the different steps of bioinformatics and statistical analysis –    Have a better biological interpretation of results –    Have facilitated exchanges with technology platforms, bioinformaticians, and biostatisticians in order to successfully complete their scRNAseq project The summer school will bring together outstanding and enthusiastic young scientists (PhD students and post-docs) from all over the world in order to exchange knowledge and ideas. It is limited to a small group of participants (20 maximum) to privilege informal interactions and scientific discussions   Application deadline: March 12, 2026 (midnight) Answers will be sent mid-April at the latest.
