Description
Moritz Sexauer and co-authors identify a signal that lets a plant's shoot direct how its roots branch. Their 2023 paper starts from a puzzle: roots adjust their growth to soil nitrogen, but the shoot seems to give the orders. The team shows that a tiny RNA called miR2111 travels from shoot to root. There it acts on a target gene known as TML, which reins in new root branches.
The same pair already had a known role in hosting nitrogen-fixing bacteria in the legume Lotus japonicus. Strikingly, the system also works in Arabidopsis, a plant with no such partnerships. That conservation marks the pair as a core, shared tool for shoot control of root shape across dicots.
