From: GC heterogeneity reveals sequence-structures evolution of angiosperm ITS2
Distribution and variation of ITS2 GC contents among angiosperms. A Histogram of ITS2 GC contents across 165 sampled genera showing a normal distribution. B a scatter plot illustrating the correlation between ITS2 GC contents and the GC contents at the third codon position of the expressed sequence tags (EST-GC3) among 107 representative genera of Eudicots, Poaceae and the non-Poaceae monocots. Each data point represents the average GC value of a genus
