A total of 1363 mutants were isolated from the M2 plants. Some of these correspond to genes previously described by other authors who used EMS or X/gamma-rays. For example, the mutant #60 (Fig. 4) is similar to the axr1-12 mutant, which shows a semi-dwarf phenotype, bushy lateral branches, and is involved in auxin-resistance pathways[20]. The mutant #164 (Fig. 6b) is similar to the rot3 mutant, which displays short petioles and rounded leaves due to a mutation in a cytochrome P-450 gene that is involved in the polar elongation of cells in the longitudinal axis [21]. The mutant #352 (Fig. 6v) is analogous to the var2 mutant characterized by a variegated stem, rosette and cauline leaves, sepals, and siliques [22], [33] and [34]. The mutant #436 (Fig. 7a) is similar to thebon1-1 mutant, which shows a dwarf phenotype with twisted leaves and short inflorescences and stems [35]. The mutant #488 (Fig. 7e) is similar to the bru1-1 mutant, which has distorted phyllotaxy (resulting in an irregular branching pattern), and a fasciated stem (thick and flattened stems) [36]. On the other hand, there were also several mutants
