  • The concentrations of the hub activity proteins are denoted by x1 = [FT], x2 = [TFL1], x3 = [FD], x4 = [LFY], and x5 = [AP1]. Kij are effective binding constants between hub activity proteins i and j, Ki:k the effective binding constants between hub activity protein i and a promoter site for the hub activity gene k, Kij:k effective binding constants between complexes of hub activity proteins i and j and a promoter site for gene k, and hi the effective Hill coefficients. pi:k is the fraction of hub activity protein i bound to a promoter site of gene k and pij:k the fraction of the promoter of gene k with the complex i and j . All degradation rates were set to δi = 0.1. We also present the parameters we used to compute the data shown in the figures and tables.
