Description
Bai-Jun Li and co-authors explain how a plant hormone holds back strawberry ripening, in a 2024 paper. The edible part of the berry is the receptacle, the swollen stem tip. Ripening needs a second hormone, ABA, while auxin from the true fruits on the surface keeps ABA low early on.
The team finds a response factor whose levels fall as auxin drops, letting ABA rise and ripening start. The factor binds the switch of a key ABA making gene and shuts it down. Forcing the factor high kept berries unripe, while silencing it sped ripening. Added ABA partly undid the block, which pins the link between the two hormones.
