Quantitative real-time-PCR expression analysis of ABS- and GOA-like genes from selected Brassicaceae. Expression quantities of mRNAs in roots, leaves, flowers and siliques are presented relative to the expression level of the corresponding ABS-like gene in floral buds, which was set to 1. Bars represent SDs. Relative expression levels of (A) ABS and GOA from Arabidopsis thaliana, (B) CrTT16 (ABS ortholog) and CrAGL63 (GOA ortholog) from Capsella rubella, (C) AalAGL32 (ABS ortholog) and AalAGL63 (GOA ortholog) from Arabis alpina and (D) EsAGL32 (ABS ortholog) from Eutrema salsugineum are depicted. A star indicates a statistically significant (P value <0.05) difference between the expression of an ABS-like gene in different tissues as compared with its expression in floral buds and a circle indicates a significant (P value <0.05) difference between the expression of ABS- and GOA-like genes in the same tissue. Note that the expression levels are shown on logarithmic (Log₁₀) scale and that there is no GOA-like gene in E. salsugineum.
