INTERVIEW - Light drives photosynthesis, but an excess can harm plants. Sanchali Nanda used a novel instrument that monitors the stress levels of plants to gain new insights on their energy dissipation mechanisms. Read more in this interview with her: upsc.se/about-upsc/new…


“The important thing is not to stop questioning. Curiosity has its own reason for existence.” Just published a new article inspiring kids to explore the wonders of science. Saumitra Dey Choudhury, PhD, DBA Maneesh Lingwan, PhD. kids.frontiersin.org/articles/10.33… #scienceoutreach #kidsinSTEM


Very happy to see our latest paper by Rory Osborne et al out today in Developmental Cell. In this work we identify a role for VRN2-PRC2 in regulating light-responsive growth in Arabidopsis through the conditional epigenetic repression of PIF signalling. cell.com/developmental-…






🍀🎉😊❤️🙏 I am so grateful and proud to be working with Catherine, Joanna, Adrienne and Nan to create the Arabidopsis timeline! Such a landmark project, published The Plant Cell & initiated by NAASC NAASC & North American ICAR


Excited to share the latest study in New Phytologist, exploring how a B-box factor integrates light and ethylene signaling to optimize seedling soil emergence. Kudos to Nevedha Ravindran, Kavuri Venkateswara Rao, and souravdatta for the efforts! Thanks IISER Bhopal Dept of Biological Sciences (DBS), IISER Bhopal nph.onlinelibrary.wiley.com/doi/10.1111/np…

Heartfelt thanks to Prof. Sourav Datta (souravdatta) for the invaluable support and guidance. Big shoutout to Venky (Kavuri Venkateswara Rao) for co-authoring the paper! Grateful to PCDB Lab (PCDB Lab IISERB) for their support. Thanks also to IISER Bhopal & Dept of Biological Sciences (DBS), IISER Bhopal!

Had great time meeting these inspiring scientists in Ghent for #ICAR2025 India Plant Science Plant functional Genomics Lab Santosh Satbhai SKB Lab souravdatta Jyothi Vadassery Shri Ram Yadav Almost 10 years since my first introduction with them at Indian Arabidopsis conference Mohali 2016 Safe travel 🙏




Out now in Nature Plants! Our study reveals: Water availability positions auxin response maxima to determine plant regeneration fates. 💧 High water → roots, low water → callus. Stress hormones fine-tune the switch. nature.com/articles/s4147…

Plants grow strong under pressure 🌱💪 Weight-induced stress causes wider stems+more vascular bundles. The response is driven by BRs & strigolactones via key signaling genes, boosting seed yield 📖doi.org/10.1111/tpj.70… Lorena Raminger julietacabello IAL-Comunica pilarcubas
