Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid‐independent manner

open access: yesThe Plant Journal, Volume 123, Issue 5, September 2025.
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...
