|a The full ORFs of three floral genes in hickory (Carya cathayensis Sarg.), CcAGL24 (the AGAMOUS-LIKE24 homolog), CcSOC1 (the SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 homolog) and CcAP1 (the APETALA1 homolog) are derived using a 5' RACE PCR protocol. Through sequence alignment and phylogenetic analysis, it is demonstrated that the three genes belong to the MADS-Box family. According to the evolutionary trees of the three genes, the homologous genes from the same family cluster well together, while those from different orders doesn't match evolutionary regularity of individual organisms. The result of Quantitative RT-PCR analysis shows that the transcriptional levels of the three genes are up-regulated in early stage and down-regulated in late stage in pistillate floral development. However, it takes different time to reach respective expression peak among the three genes. In staminate floral development, the transcription trend of the three genes is up-regulated, subsequently down-regulated, and then up-regulated again. Nevertheless, those trajectories, peaks, expression levels, inflection points are different in pistillate floral development. The result suggests that their functions are different in between pistillate and staminate floral development. The probable ordinal site of the three genes in the flowering network from top down is CcAGL24, CcSOC1, and CcAP1, which is identical to that in herbaceous plants. Moreover, several adverse environmental factors trigger several negative genes and then confine the development of staminate floral buds. Our results suggest the possible relationship among the three critical floral genes and their functions throughout the floral development in hickory
