a Hierarchical cluster analysis (based on Bray-Curtis distance) of dsr genes based on hybridization signal intensities for all wells. Every sample is named after A plant with “1”, “2” or “3” that indicates one of three replicate samples from each plant. b Relative abundance of dsr genes. The signal intensity for each functional gene category is the average of the total signal intensity from all replicates. All data are presented as mean ± SE
