Developmental Defects of the cdkf;1 and cdkd Mutants.
(A) Schematic maps of cdkf;1 and cdkd T-DNA insertion mutant alleles. Exons, blue boxes; introns, black lines; LB and RB, left and right T-DNA border repeats.
(B) Compared with the wild type (top section), the cdkf;1 mutant develops small curly serrated leaves.
(C)
cdkf;1 is severely dwarfed and shows retarded development.
(D)
cdkf;1 flowers carry serrated sepals, deformed petals, and stamens with short filaments.
(E) Upon pollination with the wild type, cdkf;1 develops normal looking siliques that contain no seed.
(F) The phenotype of cdkf;1-2 is restored to wild type (wt) by genetic complementation with a wild-type cDNA expression construct controlled by the cauliflower mosaic virus 35S promoter.
(G)
cdkd single mutants show no change in development compared with the wild type.
(H)
cdkd double and d123* triple mutants display different degrees of growth inhibition. See also Supplemental Figure 5 online.
