Fig. 5. Abnormal lateral branches observed in max1-1, max2-1 and max1-1 max2-1 double mutant shoots. (A) Lateral growth from one rosette leaf axil of wild type (left) and max2-1 (right). There is a single lateral inflorescence in wild type and two lateral inflorescences in the mutant. s, leaf subtending the lateral shoot; a, axillary leaf; i, stem of lateral inflorescence. (B-D) Fasciated lateral inflorescences of (B) max1-1, (C) max2-1, (D) max1-1 max2-1. (E-H) Transverse sections of (E) a wild-type lateral inflorescence and (F) max1-1, (G) max2-1 and (H) max1-1 max2-1 fasciated lateral inflorescences. Scale bars: 1 cm (A-D); 100 µm (E-H).
