Quantitative RT-PCR of differentially expressed ABC genes across J. calliantha floral organs and development. a JcAPETALA3 (JcAP3) is expressed as predicted in petals and stamens, and in late emerging coronas. b JcPISTILLATA/JcGLOBOSA2 (JcPI/JcGLO2) is expressed as predicted in petals and stamens, and in late emerging coronas. c JcAGAMOUS (JcAG) is unexpectedly expressed in leaves, sepals, and petals, and in late emerging coronas. d JcAGAMOUS-LIKE 1 (JcAGL1) is expressed as predicted in stamens and carpels, and in late emerging coronas. e JcAPETALA1 (JcAP1) is expressed broadly in floral organs, but is not detected in stamens. f Overlapping expression domains in each floral organ. Black, strong relative expression; gray, weak relative expression. Bars in graphs denote averages of three biological replicates with standard errors. Colors mark expression in the same floral organs between the graphs and floral diagrams. Leaves, black; sepals, green; petals, blue; stamens, yellow; coronas, red; and carpels, orange
