Variations in leaf growth parameters over time in Arabidopsis with altered CGR2 and CGR3 expression. A, LMA, B, leaf area ratio, C, leaf mass ratio, and D, root mass ratio at four different harvests (H) for Col-0, cgr2com, CGR2OX, and cgr2/3 is presented. H1, H2, H3, and H4 correspond to 29, 49, 63, and 82 DAS, respectively. Values represent the mean and n = 5 plants per line. Statistical differences at α = 0.05 are marked with lower-case letters.
