Expression profiles of the grapevine VvBBX genes during three fruit developmental stages. a Hierarchical clustering of the transcript accumulation profiles of 24 VvBBX genes during three berry developmental stages. b RT-qPCR transcript analysis of 18 selected VvBBX genes at three berry developmental stages. Berries from 3 year old ‘Fujiminori’ grapevine trees were sampled in triplicate at the fruit expanding (40DAF or DAF40), veraison (65DAF or DAF65), and ripe (90DAF or DAF90) stages throughout the growing season. The experiments were repeated three times and provided consistent results
