The petal identity gene <i>PhDEF</i> has a major binding and regulatory action in the epidermis
In flowering plants, floral organ identity is specified by the combinatorial action of homeotic genes. While the role of these genes in the early specification of organ identity is well established, their late function throughout floral organ development and in specific cell types is much less characterized. In particular, since plant organs are structured in clonally independent cell layers,…
