A total of 173 DEGs related to the floral development were discovered in our transcriptome data (Additional file 7: Table S6). These TFs were attributed to different gene families, including MADS (34 DEGs), TCP (12 DEGs), MYB (34 DEGs), ARF (9 DEGs), NAC (21 DEGs), b-ZIP (17 DEGs), WRKY (18 DEGs) (Table 6). Twenty-eight DEGs related to the flowering time were identified (Additional file 8: Table S7) and some shown in Table 7. Most of these TFs showed higher expression in the flower buds indicating that these genes might involve in the flower development.Table 6DEGs related to floral differentiation in the flower and vegetative budsGenes related to floral differentiationTotal No. of DEGsNo. of DEGs in flower budsNo. of up-regulated DEGs in flower budsNo. of DEGs in vegetative budsNo. of up-regulated DEGs in vegetative budsMADS34332985TCP12701212MYB343029115ARF97198NAC21202081b-ZIP171413134WRKY181715103 Table 7Some DEGs related to flowering time in the flower and vegetative budsGenes related to floweringTotal No. of DEGsNo. of DEGs in flower budsNo. of up-regulated DEGs in flower budsNo. of DEGs in vegetative budsNo. of up-regulated DEGs in vegetative budsPHYA11011CCA132231LHY11110FCA22111FY11011FRI31122CO21121
