Fig. 3. Genetic interactions of Pc-G mutants. (A) Comparison of emf2-10 clf-9 double mutant (arrow) and parental single mutants of same age. Note the minute size of the double mutant. (B) emf2-10 clf-9 double mutant showing cotyledons (c), a few sessile leaves (sl) and a terminal flower. Tissue-culture-grown plant. (C) emf2-3 single mutant, grown in tissue culture. Note similarity with B and D. (D) clf-2 emf2-10 double mutant, grown in tissue culture. (E) clf-2 emf2-10 ag-1 triple mutant showing minute plant with several ag– flowers. (F) clf-50 single mutant (left) compared with clf-50 swn-1 double mutant (right) to show enhanced phenotype. swn-1 single mutants (not shown) had wild-type appearance. (G) swn-1 clf-50 double mutant showing small size and reduced inflorescence bolt. (H) swn-3 clf-50 double mutant plants after about 5 week's growth in tissue culture. Arrows indicate root hairs developing from mass of callus-like tissue. (I) swn-3 clf-50 double mutant showing somatic embryo (arrow) formed on callus-like tissue. (J) swn-3 clf-50 double mutant showing green shoot-like tissue developing from primary root (arrow). The arrowhead indicates the main shoot. Scale bar: 1 mm.
