Fig. 3From: Split-root systems: detailed methodology, alternative applications, and implications at leaf proteome levelHeatmap (a) and principal component analysis (PCA, b) of the variations in the abundance of leaf proteins in partially (PDR) and totally de-rooted (TDR) plants, compared to uncut plants, 4 h, 5 days, and 10 days after de-rooting. The brackets and corresponding circles shown in a and b, respectively, highlight the clusters of proteins that were affected at the different stages following plant de-rootingBack to article page
