Fig. 7From: Integrated analysis of transcriptome and metabolites reveals an essential role of metabolic flux in starch accumulation under nitrogen starvation in duckweedThe enzyme activity of AGPase, UGPase, and SSs during nitrogen starvation at 0, 3, and 7 days. Fronds were collected at different time points and used for a starch metabolism-related enzymatic activity assay after nitrogen starvation. All data are presented as the mean of triplicate measurements ± standard deviationBack to article page
