The MADS-box genes are involved in floral development and specifying the identity of floral organs such as sepals, petals, stamens, and carpels. AP1 is specifically involved in sepal and petal development and is not involved in stamen development. If AP1 is replaced by AG, which is involved in stamen and carpel development, then it is likely that petals would be changed into stamen-like structures.
