Relative expression of MADS-box genes in 35S:TM8 plants. Panels from A to M show the relative expression of MADS-box transcription factor encoding genes in wild-type (white) and TM8 over-expressing (grey) flower organs: (SE), petals (PE), stamens (ST) and ovaries (OV). Each panel incorporates the name of the analyzed gene. Expression data (means of the normalized expression) were obtained by real-time PCR analyses. Values represent the mean of three different transgenic lines and two untransformed plants. Bars are the standard deviations from the means. Asterisks indicate values significantly different by Student’s t test from the control (P <0.05).
