Fruit ripening is a unique plant developmental process with direct implications for our food supply, nutrition and health.

The hormonal control of ripening in nonclimacteric fruit such as grape (Vitis vinifera) is poorly understood. Brassinosteroids (BRs) are steroidal hormones essential for normal plant growth but not previously implicated in the ripening of nonclimactercs fruit.

This paper shows that increases in endogenous BR levels are associated with ripening in grapevine and that application of BRs to grape berries significantly promoted ripening.

This is a significant insight into the mechanism controlling ripening in grapes,  and could have implications for the logistics of grape production and down-stream processing. (page 150)
