Figure Legend Snippet: Natural genetic variation in promoter sequences is predicted to alter the molecular phenotype (dynatype). ( A ) GI transcript levels under 10L:14D cycles were simulated in U2020.5 (white region, light interval; shaded region, dark interval). The K d for CCA1 binding to the promoter of GI was calculated using the EMA matrix (Fig. ), for all GI promoter sequences from the 1001 Genomes Project (dashed lines). The model retained the default GI gene (solid line, second highest peak), while a second copy that simulated only GI RNA production was tested with the K d for each promoter sequence and plotted (dashed lines). The range of dynamics shown reflects only altered GI transcription rates, without the effects of altered GI protein dynamics. ( B ) Connecting models (adapted from Millar, Fig. ). The central circuit represents the conceptual steps as a genome, in cells, builds organismal traits (upper arrow) in a given environment (green shading). Those traits and potentially management inputs (yellow), in populations, lead to selection on genome sequences (lower arrow). The black, green and cyan arcs represent, respectively, the clock gene circuit models such as U2020 (schema from Urquiza-García and Millar, Supp Fig. ), the Framework Model version 2 for clock-controlled seedling and rosette growth in simple environments (FMv2; Chew et al, ), and the FM-life model for whole-lifecycle simulation under natural environments (Zardilis et al, ). This paper illustrates how a clock gene circuit model can incorporate genome sequence data (dashed black arc), via promoter sequences that alter CCA1 binding, as in ( A ). Others might connect such models in future and add simulated genetic variation (pink), in order to explain and predict both the operation and the evolution of the plant clock genes.
