Comparison of Hj PHAN and Hj STM Expression in H. japonicum Shoots.
(A) to (C) Longitudinal sections of the same vegetative shoot.
(A) Hj PHAN was expressed in the distal part of the youngest leaf primordium (L1).
(B) Expression of Hj STM was restricted to the basal part of L1.
(C) Negative control using the Hj PHAN sense probe.
(D) and (E) Longitudinal sections of the same reproductive shoot.
(D) Hj PHAN was expressed in the distal part of the youngest bract primordia (B1 and B2).
(E) Expression of Hj STM was restricted to the basal part of B1 and B2.
(F) and (G) Longitudinal sections of the same reproductive shoot older than ([D] and [E]).
(F) Hj PHAN was expressed in a spathella (S) and distal parts of B1 and B2.
(G) Hj STM was expressed in the entire floral meristem (FM) and not in the spathella (S).
Asterisks indicate vacuolated cells. B1 to B4, youngest to oldest leaves; FM, floral meristem; L1 to L3, youngest to oldest leaves; S, spathella. Bars = 50 μm.
