a Simplified schematic representation of the conserved and intertwined carotenoid and apocarotenoid pathways in the three organisms of this work. b Heatmap of metabolite levels under the different conditions/samples; the color and symbol codes are as in Fig. 2 and can be found in the bottom right corner of the figure. c Pigment pool fluctuations due to stress exposure. Areas relative to size of pigment pool/contribution of individual pigment to the pool normalized on Pp t0 (see key and individual values written below each pie). The total size of the pie reflects the overall size of the pigment pool; for an alternative visualization of the pigment data, see Supplementary Fig. 13. d Expression changes of important homologous genes likely salient to carotenoid metabolism in the first 6 h of stress exposure (only one respective homolog shown also in some cases more were present; for the expression profiles of all detected homologs and all correlations, see Supplementary Figs. 14–17). e Relative change of selected metabolite levels/ratios in the first 6 h of stress exposure relative to the average value of t0 normalized by DW of sample, recovery rate of measurement, and molecular mass of the respective metabolites. 6MHO, 6-methyl-5-hepten-2-one, 9-cis-β-car, 9-cis-β-Carotene, 9-cis-neox, 9-cis-Neoxanthin, (A + Z)/(V + A + Z), (Antheraxanthin + Zeaxanthin)/(Violaxanthin+Antheraxanthin+Zeaxanthin), antherax, Antheraxanthin, β-car, β-Carotene, β-car/9-cis-neox, β-Carotene/9-cis- β-Carotene, β-Car/β-CC, β-Carotene/β-Cyclocitral, β-Car/β-IO, β-Carotene/β-Ionone, β-Car/DHA, beta β-Carotene/Dihydroactinidiolide, β-Car/β-CC + β-IO + DHA, β-Carotene/(β-Cyclocitral + β-Ionone + Dihydroactinidiolide), β-CC, β-Cyclocitral, β-IO, β-Ionone, Chl a, Chlorophyll a, Chla/Chlb, Chlorophyll a/Chlorophyll b, Chl b, Chlorophyll b, DHA, Dihydroactinidiolide, DHA/β-IO, Dihydroactinidiolide/β-Ionone, violax, Violaxanthin, V + A + Z/Chla + Chlb, (Violaxanthin + Antheraxanthin + Zeaxanthin)/(Chlorophyll b), Zeax, Zeaxanthin.
