Non-metric multidimensional scaling (NMDS) graph depicting the relative importance of variables (arrows) explaining the transgenic and wild-type control lines composition. Ellipses denote the dispersion around the mean values of each iTarget. The individual points are the ordenation of each line and they are colored and symbolized according to their silencing level. The centroids are the average of the levels of the factors indicated. alpha, α-gliadins content; gamma, γ-gliadins content; omega, ω-gliadins content; gli, total gliadin content; HMW, total high molecular weight glutenin subunit content; LMW, total low molecular weight glutenin subunit content; glu, total glutenins content; gli.glu, ratio total gliadins content/total glutenins content; prolamin, prolamins content; non_gluten, non-gluten proteins; SDSml, SDS sedimentation test; Weight1000, thousand seeds weight.
