Each data set represents independent experiments using at least five different mutant and wild-type root samples. The roots used have the same developmental stage in each data set, but are of increasing age in the following lanes. The nos. in bold represents the average of the data from those three experiments.

^a Percentages are calculated based on wild type being 100%. 

^b Difference between wild type and mutant significant at P < 0.05.
