Summary of expression of MADS-box genes involved in the differentiation of selected floral organs of E. pusilla. a Expression of EpMADS4/14 (in black) correlating with a sepaloid-petaloid identity is high in the lateral sepals (left side) but low in the remainder of the perianth (right side), b Expression of the lip complex EpMADS5/13/16 (in white/grey)) correlating with a lip identity is high in in the lip and callus (left side) but low in the remainder of the perianth (right side). Expression of the sepal/petal-complex EpMADS3/15/16 (in black/grey) correlating with a sepal and petal identity is low in the lip (left side) but high in the sepals and petals (right side), c Expression of EpMADS20/23 (in white) correlating with a stelidia-stamen identity is high in the stelidia (left side) but low in the stamen (right side). Expression of EpMADS6/22 (in black) is low in the stelidia (left side) but high in the stamen (right side)
