Fig. 6From: Integrated analysis of transcriptome and metabolites reveals an essential role of metabolic flux in starch accumulation under nitrogen starvation in duckweedHeatmap of metabolite contents of duckweed fronds during nitrogen starvation. Fronds were collected at different time points and used for metabolite content measurement. The fold change of contents is indicated by the scale bar. Red indicates a higher content, while yellow indicates a lower contentBack to article page
