Expression divergence is thought to be a hallmark of functional diversification between homologs post duplication. Modification in regulatory elements has been invoked to explain expression divergence after duplication for several MADS-box genes, however, verification of reciprocal loss of cis-regulatory elements is lacking in plants. Here, we report that the evolution of MPF2-like genes has entailed degenerative mutations in a core promoter CArG-box and an auxin response factor (ARF) binding… CONTINUE READING
