Flowering network in hickory based on that in Arabidopsis It shows 3 stages latitudinally (signal transduction, signal integration, floral organ development) or 5 pathways (photoperiod, vernalization, autonomous, gibberellic acid (GA), and sucrose pathways) longitudinally to flowering. Circle in gray presents a flowering or floral gene lies in A. thaliana but hasn’t been discovered in hickory. Rectangle in reddle presents a common flowering or floral gene in both SampleA and SampleB. Rectangle in green presents a specific flowering or floral gene in SampleA, while Rectangle in pink presents that in SampleB. Rectangle with blue border presents a differentially expressed flowering or floral gene. Circle in dotted line presents a protein complex.
