Fig. 6. blr interacts with as stm1 but not with bel1. (A,B,F,G,H) Whole plants and (C-E) seedlings of bp (A), blr bp (B), blr as1 (C), blr as1 stm-11 (D-F), bel1 (G) blr bel1 (H). (A) The bp mutant is reduced in stature, pedicels are short and flowers hang down. (B) The blr bp double mutant is much reduced in stature compared with either single mutant. Double mutants also have additional leaves, pedicels are short and siliques tend to hang down (inset in B). (C) Twelve-day-old emerging shoot of blr as1 seedling compared with (D) blr as1 stm-11 sibling, with only a single vegetative leaf. (E,F) Occasionally vegetative shoot growth is resumed in blr as1 stm-11 triple mutants. Leaves in the double and triple mutant have an as1 phenotype. (G) The phenotype of the bel1 mutant is confined to the ovule. Siliques do not elongate as plants fail to set seed. (H) The double blr bel1 mutant fails to set seed as in bel1 single mutants. The phyllotaxy is disturbed and stature is reduced as in blr single mutants. Scale bars: 2.5 cm (A,B,F-H).
