The MIK region rather than the C‐terminal domain of AP3‐like class B floral homeotic proteins determines functional specificity in the development and evolution of petals

In core eudicots, euAP3-type MADS-box genes encode a PISTILLATA (PI)-derived motif, as well as a C-terminal euAP3 motif that originated from a paleoAP3 motif of an ancestral APETALA3 (AP3)-like protein through a translational frameshift mutation. To determine the functional and evolutionary relevanc... View More
