Fig. 6. Ectopic expression of JAG in bop mutants. JAG
(A,C,D) and BOP2 (B) expression, as determined by in situ
hybridization. (A-C) Vegetative shoot apex from 11-day-old wild-type (A,B) and
bop1-5 bop2-2 (C) plants. (A) JAG is expressed in the distal
parts of leaf primordia (brackets). (B) BOP2 is expressed in the
proximal parts of leaf primordia (bracket). (C) In bop1-5 bop2-2, JAG
is ectopically expressed in the whole leaf primordium (brackets). (D) Section
through a bop1-5 bop2-2 flower. JAG shows a uniform
expression in the bract (arrowhead). Scale bars: 100 µm.
