FIGURE 2

A simplified schematic of the core flowering time regulatory network in Arabidopsis. Colors of the nodes represent current information on orthology of these genes in the lettuce genome. Please refer to Srikanth and Schmid (2011); Bouché et al. (2015), and Wils and Kaufmann (2017) for examples of detailed depictions of these complex pathways. (CO: Constans; FLD: Flowering locus D; FRI: Frigida; FT: Flowering locus T; GA3OX1: Gibberellin 3-beta-dioxygenase 1; LFY: Leafy; PHYA: Phytochrome A; PHYB: Phytochrome B; SOC1: Suppressor of CONSTANS overexpression 1; SPL: squamosa promoter binding protein like; SVP: Short vegetative phase.)
