Fig. 4. Gene expression studies. (A-E) In situ RT-PCR of (A) EGL3
expression, (B) control minus primers, (C) GL3::GUS expression
pattern, (D) GL2::GUS expression in wild type and (E)
GL2::GUS expression in egl3 gl3 mutant. (F) LUX RT-PCR
analysis of CHS and DFR. Gene expression levels relative to
ttg1 are given above the bars. CT values and s.d. are
given below the genotype and test gene labels.
