We have written a review on MADS-box genes expression in developing floral organs, which has been under-explored as compared to their early role to specify floral organ identity. Congrats to Emma Désert for her first review article as a PhD student! #proudPI @rdplab.bsky.social

Women’s use of AI is perceived as a sign of incompetence, while men’s use of AI is seen as an indication of initiative. 🤦🏻‍♂️
