Humbled to be a part of Indian Science Academies, @ IAScBng, @nasi_academy, and Now @insa_academy
Such moments remind me how fortunate I am to work with talented lab members (past and present), collaborators, colleagues and mentors all along. Thank you for this opportunity 🙏

Honoured & excited that ‘Breathing Underground’ has been funded by the ERC!
This will let me explore one of the most fundamental questions of plant life: how roots breathe underground? @erc.europa.eu

Amazing how responsive different regions of the same tissue type is to tissue culture hormones! Here is the hypocotyl of a plant segmented into lower hypocotyl (seedling stem near root crown) left, middle hypocotyl, and upper hypocotyl right (seed stem near cotyledons).

Inducible RUBY expression in independent transformant lines of A.thaliana over 4 days.

Several lines (top) show induction everywhere except the petals... cool but I'd prefer the opposite!!

🧪🌾News - How do seedlings straighten when emerging from the soil?🔬

@srobertgroup.bsky.social & collaborators have identified a protein that promotes this seedling straightening via the plant hormone auxin.
