Fig. 8. CYCA and SIM expression in cpl3 mutant and transgenic Arabidopsis plants expressing CPL3. Real-time PCR analysis of CYCA2;1 (A), CYCA2;2 (B), CYCA2;3 (C), CYCA2;4 (D), CYCA1;1 (E) and SIM (F) in wild type, cpl3, 35S::CPL3 and CPL3p::CPL3 at four developmental stages. Expression levels of each gene were normalized to ACT2 expression. Relative expression levels: expression levels of each gene relative to wild type at 12 days. The experiment was repeated four times. Error bars indicate s.d. Student's t-test, ^*P<0.020 versus wild type.
