Phylogenetic relationship, motif and gene structure analysis of grape 14–3-3 members. (a) Phylogenetic tree of 14–3-3 family in V. vinifera. Bootstrap values less than 40 were cut off. (b) Gene structure and motif analysis of grape 14–3-3 members. The black blocks represent the untranslated region (UTR), the gray blocks represent exons, and the black lines represent introns. Different motifs were represent in different colour blocks, and their sequences were list in c. (c) The amino acid sequences of motifs in VviGRF proteins. Arrows showed the intron position appeared in “exon-intron-exon” sequences. Red arrow means the epsilon group, green arrow means the non-epsilon group. The detail information for the intron position was shown in Additional file 7
