A total of 240 genes associated with flowering time were obtained (Additional file 6: Table S5). These include floral meristem identity genes LEAFY (LFY) and APETALA1 (AP1); autonomous pathways genes FCA, FPA, FLOWERING LOCUS (FLD), FY, FVE, FLOWERING LATE KH MOTIF (FLK); vernalization pathways genes FRI and VERNALIZATION INSENSITIVE (VIN); photoperiod pathway genes such as FT, Phytochrome A (PHYA), Phytochrome B (PHYB), PIF3, ELF3, LHY, SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1), CIRCADIAN CLOCK ASSOCIATED1 (CCA1) and CO; Gibberellin (GA) pathway genes such as GIBBERELLIC ACID INSENSITIVE (GAI). All these unigenes provide important resources for future study of floral organ development, floral bilateral symmetry and flowering time.
