Genome-wide identification and analysis of B-BOX gene family in grapevine reveal its potential functions in berry development

Background The B-BOX (BBX) proteins are the class of zinc-finger transcription factors and can regulate plant growth, development, and endure stress response. In plants, the BBX gene family has been identified in Arabidopsis, rice, and tomato. However, no systematic analysis of BBX genes has been undertaken in grapevine.
