You know that thing when you are starting a new project and exploring the regulated genes, then you find a gene that you don't know regulated by what you work on. Then you look up the reference for it and it is your own paper from ~20 years ago. Yeah, that happened today. - A real full circle event

IPGSA 2025 is over, but there were many great talks and meetings with old and new plant hormone friends. See you all in Vienna if not sooner. #IPGSA

Excited to head out to IPGSA and see lots of great science on plant hormones! The lab is busy making posters to show what we have all been doing.

These are the types of reviews with commentary (Unanswered questions) that I really like seeing, as they combine expert opinions with what we don't know - and should be working on!
