Figure 2.

Conserved motifs of grapevine CBL (A) and CIPK (B) proteins and gene structures of grapevine CBL (C) and CIPK (D) genes. The conserved motifs of VvCBL and VvCIPK proteins were performed using MEME program and arranged corresponding to the phylogenetic tree. Different motifs are highlighted with different color boxes and numbers. The length of boxes corresponded to motif length. The gene structures were drawn using the GSDS program. The yellow boxes represent exons, the lines represent introns and the blue boxes represent upstream/downstream UTRs. Subgroup B, C, D, and E of grapevine CIPK family constituted an obviously intron poor clade.
