Molecular dissection of the role of auxin in fruit initiation.
Fruit set and growth usually requires fertilization. Fruit set and development without fertilization is called parthenocarpy. Feeding auxin to virgin flowers induces fruit development without fertilization. Recent studies by Hua Wang et al. and Marc Goetz et al. have identified molecular events leading to fruit initiation in the absence of fertilization, showing that parthenocarpy can be achieved by altering different steps of the auxin signaling pathway. Thus, independent evidence indicates that auxin plays a key role in fruit initiation.
