Fig. 7From: De novo transcriptome analysis and glucosinolate profiling in watercress (Nasturtium officinale R. Br.)Expression of indolic glucosinolate biosynthetic genes in different organs of N. officinale. The expression level was measured in 2-month-old N. officinale. Relative expression level was plotted after normalization to UBC9. Mean values and SDs from triplicate biological experiments are plottedBack to article page
