🔬3D Cell segmentation of the shoot apical meristem (SAM) of maize🌽in top/side view was analyzed by Dr Cecilia Lara Mondragon from the University of Tübingen. 💡The SAM consists of pluripotent stem cells that determine the cell number and position of all lateral organs during plant shoot development.

⌛One month until early bird registration and abstract submission deadline! The International Symposium on 🌽Cereal Meristems and Stem Cell Systems 🌱 organized by @cerealcell.bsky.social will take place in Regensburg (Germany) from Sep 28 – Oct 1, 2025. Register until June 30: www.cscs2025.de

🔬 Proliferating cells in a barley inflorescence meristem visualized by Jan Maika, Heinrich Heine University Düsseldorf. 💡Cell proliferation is characterized by de novo DNA synthesis. Incorporation of 5-Ethynyl-2′-deoxyuridine, a thymidine analogue, detected with a fluorescent azide molecule in vivo.

🔬 This photo taken by Dr Yaping Zhou (University of Bonn) shows that defects in the lateral root system inhibit nutrient uptake and thereby affects the entire plant development in maize. 🌽While the WT has a normal leaf phenotype, the lateral root defective mutants have significantly smaller leaves.🍃

Early bird registration is ending soon! Get ready to connect, collaborate, and innovate at the International Symposium on Cereal Meristems and Stem Cell Systems! 📍 Where: University of Regensburg, Germany 🕒 When: 28th September - 1st October 2025 💻 Registration: cscs2025.de

📷This photo of the construction site 🏗of a new greenhouse at the Institute of Plant Sciences was taken by Prof Dr Grasser (University of Regensburg). 👷 A greenhouse that allows to grow even tropical maize 🌽 lines of about 4 m height indoors at highly controllable conditions 💦🌞🌡is taking shape. 🎉

🔬 This field photo of a maize cross was shared by Cecilia Lara Mondragon from the University of Tübingen. 💡 Maize is about 95% wind-pollinated by pollen by neighboring plants. For controlled crosses, the female ear is covered, and pollen from a selected male plant is manually applied to the silks.

🔬 Insights into the depths of a maize ovule primordium were provided by Martina Balboni from University of Hamburg. 💡 The chromosome axis protein DSY2 fused to YFP (in yellow) and the RFP labeled TUBULIN2 (in magenta) were visualized in a live cell imaging approach during maize meiosis.

🔬 Scanning electron microscope picture of an immature maize tassel tip taken by Jia-Chi Ku (University Regensburg). 💡 Via several intermediate meristem stages (see picture) the tassel (male inflorescence of maize) with hundreds of male flowers, which contain the pollen producing anthers, is formed.

🔬 Maize embryo at 8 days after pollination, prepared by Dr Guojing Jiang, University of Regensburg. 💡 Plant embryogenesis is the process by which embryos develop from the fertilized zygote, involving the establishment of apical-basal polarity, meristem initiation, and lateral organ formation.

🔬 An image competition was organised at the Biologists @ 100 conference in Liverpool. The extraordinary image of the mature leaf epidermis of Brachypodium by Lea Berg @lbmountain.bsky.social is one of 15 finalists 🏆 in the Company of Biologist's @focalplane.bsky.social competition.👏 #Biologists100

🎬After months of preparation by Martina and Cecilia, the on-site filming of the CSCS video took place in Regensburg with the support of Guojing and PICT GmbH. 📽 Looking forward to share our research topic 🔬🧪 and why doing research on stem cells in plants 🌱 is important for the future.

🔬 This colorful picture shows the expression of MADS box genes in a young barley spike. The mapping was carried out by Jan Maika from Heinrich Heine University Düsseldorf. 💡 MADS box genes code for transcription factors that regulate a.o. flower development, fruit formation and seed maturation.

🔬 The expression pattern of the epidermis marker gene HvOCL7a in a barley shoot apex was visualized by Dr. Thirulogachandar Venkatasubbu from Heinrich Heine University Düsseldorf. 💡 The shoot epidermis protects plants from dehydration and pathogens and maintains shoot stem cells.

🔎 Our PI Frank Hochholdinger from @unibonn.bsky.social received the 2025 maize genetics cooperator award 🏆 at the 67th maize genetics conference together with Caroline Marcon for their work on BonnMu a public transposon-tagged maize population designed for genetics studies in maize.🎉 #MGM2025

The DFG Research Unit Cereal Stem Cell Systems invites you to the INTERNATIONAL SYMPOSIUM ON CEREAL MERISTEMS AND STEM CELL SYSTEMS Sun. 28th Sept. 2025 – Wed. 1st Oct. 2025 University of Regensburg, Germany For more detailed information and registration please visit our website www.cscs2025.de

Excellent talk by Yaping Zhou of @unibonn.bsky.social and @cerealcell.bsky.social at the development and cell biology workshop prior to the 2025 maize genetics meeting in St. Louis. #MGM2025.

🔬 This cell arrangement of a barley root apical meristem (RAM) was visualized by Anika Dolata from Goethe University Frankfurt using Renaissance blue staining. 💡. The stem cell niche in the RAM provides a pool of undifferentiated cells that can be activated when needed for root growth.

🔬 The photo taken by Dr. Yaping Zhou from the University of Bonn shows the maize root morphology after 7 days of germination. 💡 The root system of maize🌽 develops from a primary radicle, followed by 3-5 seed-borne seminal roots. Lateral roots are essential for efficient water and nutrient uptake.💦

🔎 Our PI PD Dr. Karina van der Linde from the university of Regensburg has presented her work on “Cell division in freshwater algae and land plants 🌱 governed by a novel, conserved plant peptide hormone” in a great talk at the #MBP2025 Conference in Hennef, Germany. 👍 @molplantsci.bsky.social

👏Many thanks to our PI Prof. Dr Rüdiger Simon for sharing the importance of our research on plant meristems 🌱🌽🌾with a broad audience during his great keynote lecture 👌 at the Molecular Biology of Plants Conference of the DBG (@plantsciencedbg.bsky.social) in Hennef, North Rhine-Westphalia, Germany.

🔬This beautiful picture of a 7-day-old vegetative shoot apical meristem (SAM) of maize 🌽 was taken by Dr. Cecilia Lara Mondragon from the University of Tübingen. 💡 SAMs harbour a population of pluripotent stem cells which give rise to all organs above-ground.

📢With regular posts of pictures 📷 🔬from our current cereal stem cell research, we want to whet our followers' appetite for plant research. 🌾🌽 🎉Many thanks to all our PhD students and PostDocs for these beautiful contributions that show the unique aesthetics of plant research!🌱

🎉Our junior research group leader Dr Karina van der Linde successfully defended her habilitation on 15 January 2025. 🥂 We would like to congratulate her and wish her the best of luck 🍀 and success for her future career!

Our 3rd annual CSCS meeting, which took place in December 2024 in Bern, provided a unique opportunity for the entire RU to discuss our research in the beautiful Swiss mountain landscape. Many thanks to you all for 3 days of fantastic scientific presentations 👏 great discussions and inputs ❤️!!!
