WebThe ABC model for the specification of floral organ identity, published 15 years ago, has proven to be a useful framework for interpreting floral development data from a wide variety of species. In Arabidopsis, A‐function (specification of sepal and petal identity) is attributed to two unrelated genes, APETALA1 ( AP1) and APETALA2 ( AP2 ).
