Overall averages for controls (n = 6 individual plants) are presented with standard deviation. Z scores represent the number of standard deviations each RNAi plant measurement is from the control average, with z scores greater than 2 or less than −2 highlighted in italic font. Plants are listed in ascending order of total lignin content
