Table 2.

Classification of the Antirrhinum mutants according to the combination of highly significant PCs (p<0.01%) in the allometry model. Gene abbreviations are as described by Hammer et al. (1990) and Stubbe (1966). The + or − sign corresponds to the way the corresponding PCs are affected in the leaf mutant (as compared to the mean). Cloned genes are in bold (Golz et al., 2002; Golz et al., 2004).
