Plant hormone trafficking

Brassinosteroids en route

Nature Chemical Biology volume 19, pages 1294–1295 (2023)Cite this article

Subjects

Brassinosteroid (BR) hormones promote root growth by controlling meristem size and cell elongation, but the mechanism of BR transport remains elusive. A new study shows that BR precursors move via intercellular pores called plasmodesmata to modulate BR cellular levels and their signaling functions.
