Additional file 1 of Identification of BBX gene family and its function in the regulation of microtuber formation in yam

Additional file 1: Supplementary Table 1. The information of BBX family genes in D. rotundata. Supplementary Table 2. The information of BBX family genes in D. alata. Supplementary Table 3. The information of BBX family genes in D. opposita ‘Tiegun’. Supplementary Table 4. Homologous BBX gene pairs between D. alata, D. rotundata, O. sativa and A. thaliana. The homologous gene pairs were identified by the results of BLAST and collinearity analysis. When both Ka and Ks were equal to 0, Ka/Ks was considered equal to 1. When only Ks was equal to 0, it was marked as Ka >> Ks. Segmental means that the gene might arise from segmental duplication. Tandem means that the homologous sequences in close genomic proximity. Supplementary Table 5. Primers used for gene cloning, semiqRT-PCR and qRT-PCR detection of DoBBX2 and DoBBX8. The double underscores represent the pBI121 plasmid based linker sequences. The restriction endonuclease recognition sites for Sac I and Xba I were included in the respective oligonucleotide primers, which are markered with single underlines. Supplementary Table 6. Accession numbers of the protein sequences used in phylogenetic analysis of DoBBX2 and DoBBX8.
