Abstract 【Objective】 This study aimed to identify the whole genome WOX (WUSCHEL-related home obox) gene family in Tartary buckwheat and reveal the correlation with sequence characteristics of its gene family members, gene expression pattern and the rate of callus induction. It provides a theoretical basis for breaking through the regeneration and genetic transformation problem of Tartary buckwheat. 【Method】 The protein and nucleic acid sequence of the WOX gene family members in Tartary buckwheat were obtained by homology blast and the sequence of Arabidopsis WOX genes were served as reference. Based on protein homology and conserved domain analysis, all members of Tartary buckwheat WOX gene family were identified. The TBtools software was used to further demonstrate the characteristics of the WOX genes in Tartary buckwheat, including gene structure, conserved domain and cis-acting element. Genomic collinearity of WOX gene family members between Tartary buckwheat and Arabidopsis thaliana was analysed. Based on proximity method, the MEGA X software was used to perform phylogenetic tree of these WOX genes in Tartary buckwheat, Arabidopsis and rice. The hypocotyl explants of 70 Tartary buckwheat varieties were cultured with MS+2,4-D 3.0 mg·L -1+6-BA 1.0 mg·L-1 for callus induction and the callus emergence rate of different genotypes was evaluated. The FtWOX gene expression level was performed by qPCR to compare the different Tartary buckwheat varieties with high and low callus yield. The correlation between callus rate and FTWOXS gene family members was analysed based on Pearson correlation coefficient. 【Result】 A total of 30 WOX genes were identified in Tartary buckwheat and they were unevenly distributed on 8 chromosomes. The 30 Tartary buckwheat WOX genes could be divided into three groups by phylogenetic tree. The WOX genes contained different conserved domains in different groups, and the main conserved domains were HD(Homeodomain), START and MEKHLA. The conserved motif analysis showed that the conserved motif number of FtWOX genes may contain 2 to 10 motifs, and the gene structure analysis showed that the number of exons contained in the genes between 2 to 18. Promoter elements analysis showed 26 different kinds of cis-acting elements in the 30 WOX genes. The phylogenetic analysis showed that 30 Tartary buckwheat, 15 Arabidopsis thaliana and 12 rice WOX gene family members could be divided into three categories, of which the third group is unique to Tartary buckwheat. The collinearity analysis showed that six WOX genes were genomic collinearity between Tartary buckwheat and Arabidopsis thaliana. Expression pattern and correlation analysis show that the expression level of FtWOX1/FtWOX12/FtWOX22/FtWOX23/ FtWOX24 has positive correlation with the callus induction. 【Conclusion】 Collectively, these data suggest that the Tartary buckwheat FtWOX members showed abundant sequence variation characteristics. The expression level and callus rate of WOX gene in different Tartary buckwheat genotypes were significantly different and correlated to some extent, suggesting that different Tartary buckwheat WOX genes had potential functional diversity.
