Fig. 4. CUC2 in situ hybridisation on longitudinal sections of
inflorescence apices. (A) Wild type. (B,C,D)
CUC2g-m4 transgenic plants. (C) Twisted stem with CUC2
expression on the inner side. (D) Close-up of the inner and outer sides of C.
Arrows point to the lowest axils with detectable CUC2 expression.
Arrowheads indicate ectopic CUC2 in the internodes. Scale bars: 100
