Extended Data Figure 5: Integrative analysis of flowering time.
From: The sunflower genome provides insights into oil metabolism, flowering and Asterid evolution
a, Flowering time network in the sunflower. Flowering time genes of A. thaliana and their interactions are drawn in green. Sunflower genes and orthology relationships with A. thaliana genes are shown in orange. b, Genomic architecture of flowering time in the domesticated sunflower. Outer ring, location of genomic regions associated with flowering time. Inner ring, links between ohnologues of a sunflower-specific whole-genome duplication (WGD-2), limited to genes located in regions associated with flowering time. Links between ohnologues of WGD-2 that are both located in regions associated with flowering time are drawn in red, other links are drawn in grey. c, Pathway of the integration of flowering signals in meristem (simplified pathway adapted from ref. 20). The bright orange backgrounds indicate genes for which at least one sunflower orthologue was located in a region associated with flowering time. Bold italic genes indicates genes for which we identified additional in-paralogues compared to a previous study using more limited genomic data21. Simple arrows represent positive regulation and other arrows negative regulation. Curved lines between genes represent protein–protein complexes.
