FIGURE 4.
Analysis of MADS-box gene expression during carpels and ovules development. Expression profiles of MADS-box genes obtained from carpels and ovules at two different stages of development (early and late stages) of the floral bud. The expression profiles were obtained by qPCR experiments; values in the graphs represent initial RNA quantities ± SEM. Black asterisks above an expression level indicate a significant difference between the two developmental stages, for that specific gene. Red asterisks indicate a significant difference of the expression levels of genes under the red bar (∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001).
