1. Scanning electron micrographs of developing axillary shoots at the base of the oldest pair of leaves of wild type (A-D), max1-1 (E-H) and max2-1 (I-L).
Scanning electron micrographs of developing axillary shoots at the base of the oldest pair of leaves of wild type (A-D), max1-1 (E-H) and max2-1 (I-L). Plants were fixed after days of growth in long photoperiods. The figure shows normal wild-type buds and mutant buds that appeared abnormal. Scale bars: 100 μm. (A,E,I) Semicircular zone marks initiation of axillary shoot. The size increased in some mutant axils. (B,F,J) Axillary shoot meristem bulging out. The size increased in some mutant axils. (C,G,K) Formation of axillary leaf primordia. Two primordia form at opposite positions in the wild type, but the position can be random in the mutants. (D,H,L) Leaf bases with more than one axillary shoot meristem. One of the two axillary shoots is retarded in the wild type, but in the mutants both develop.
