Rubisco is an important but challenging protein engineering target. Fast and selective rubiscos could enhance photosynthesis in plants and accelerate biobased production processes. To facilitate engin...

Approaches combining genetic association and Perturb-seq data that link genetic variants to functional programs to traits are described.

Le réseau « Saclay Plant Sciences » (SPS) organise en 2026 une Ecole d’été dédiée aux approches de single cell RNAseq (scRNAseq) appliquées aux plantes. Pendant cinq jours, doctorants et post-doctorants pourront se former à toutes les étapes d’un projet de scRNAseq : conception expérimentale, préparation d’échantillons, choix des protocoles, analyses bioinformatiques et interprétation des résultats.   L’Ecole d’été est coordonnée par Bruno Guillotin de l’IPS2, et les sessions, animées par des experts de l’IPS2, de l’IJPB, du VIB Ghent et de l’Institut Pasteur, mettront en lumière les spécificités des modèles végétaux et aideront les participants à sélectionner les méthodes les plus pertinentes pour leurs travaux.   Limitée à 20 participants, cette école internationale offrira un cadre privilégié pour échanger, poser des questions et approfondir ses compétences en scRNAseq végétal.   Lien pour les inscriptions (date limite 12 mars 2026)

### Competing Interest Statement The authors have declared no competing interest.

Bruno Guillotin has joined the IPS2 unit (Institute of Plant Sciences Paris-Saclay) as a CNRS Research Scientist. He was recruited in February 2025.   After studying Plant Biology and Physiology, he completed his PhD between 2013 and 2016 at the Plant Science Research Laboratory (LRSV – Toulouse) under the supervision of Guillaume Bécard and Jean-Philippe Combier. His doctoral work focused on the autoregulation of arbuscular mycorrhizal symbiosis in Medicago truncatula.   Following his PhD, he turned his attention to the study of root development in various plant species as a postdoctoral researcher in Kenneth Birnbaum’s group at New York University. There, supported by a Human Frontiers Long-Term Fellowship, he developed numerous protocols for single-cell transcriptomics (single-cell RNA-seq), which he implemented to study gene evolution across agronomically relevant species (maize, sorghum, millet), as well as to investigate cell regeneration in the roots of Arabidopsis thaliana.   In 2025, he was appointed as a CNRS Research Scientist and was also awarded the CNRS–INSERM ATIP-Avenir grant. At IPS2, Bruno Guillotin’s research focuses on understanding how plant cells communicate through plasmodesmata, aiming to identify which proteins and peptides move from one cell to another and contribute to organ morphogenesis in plants. His work combines single-cell RNA-seq, proteomics, genomics, and bioinformatics approaches.   Contact email : [email protected]
