Multiple sequence alignment of VviGRFs. VviGRF proteins were aligned using ClustalX2 program. ɑ helices of VviGRF proteins were analysed by searching SOPMA website, and were marked on their corresponding sequences. VviGRF-like1 and VviGRF-like2 respectively are the longest and the shortest amino acid sequences among VviGRFs, and they show very different motif and intron-exon structures with other 14–3-3 members (Fig. 3b). In order to present a more visualized secondary structure of VviGRFs, nine VviGRF proteins were used except for VviGRF-like1 and VviGRF-like2
