Fig. 6: VOC emission and time-ordered gene co-expression networks related to rose scent during flowering.
From: Multi-omics analyzes of Rosa gigantea illuminate tea scent biosynthesis and release mechanisms
a Five flower developmental time points (S1–S5) of RG. b Major VOC changes in RG from S1 to S5. c Changes in aroma intensity during flowering in Rosa gigantea (RG). The darker shades correspond to greater intensity. d Heatmaps of average TPMs (z-score normalized) at each level of TO-GCNs at each flowering time point in RG. Three flower scent-related stages were identified based on expression profiles: initial (S1), transitional (S2-S3), and terminal (S4–S5). e Predicted gene co-expression networks and connections among VOCs (rhombus), enzymatic genes (hexagon), and TFs (circle) involved in phenylpropanoid/benzenoid (yellow nodes), terpenoid (pink nodes), and fatty acid derivative (purple nodes) biosynthetic pathways. L1 to L7 indicate the levels identified in three time-ordered gene co-expression networks (RG-specific, RC-specific, and the consensus TO-GCNs). Edges between enzymatic genes are not shown. f Changes in aroma intensity during flowering in R. chinensis ‘Old Blush’ (RC). g Heatmaps of average TPMs (z-score normalized) at each level of TO-GCNs at each flowering time point in RC. Three flower coloring stages were identified based on expression profiles: initial (S1), transitional (S2–S3), and terminal (S4–S5). h Major VOC changes in RC from S1 to S5. i Five flower developmental time points (S1–S5) of RC.
