Detrimental impact of sulfide on the seagrass Zostera marina in dark hypoxia
Fig 2
Metabolomic fingerprinting of Zostera marina leaves over time using PCA.
PCA scores plot that captures the time-related metabolomic fingerprinting of compounds found in Zostera marina leaves when exposed to varying sulfide levels over a span of 120 minutes. The upper panel shows component 1 vs component 2 and the lower panel shows component 2 vs component 3. Triangles indicate samples under high sulfide levels (> 2 mM H2S) and squares samples under sulfide absence; different colors indicate varying time points. The Venn diagram indicates the number of metabolites with high influence on sample separation on the respective component.
