Orchids are known for their beauty and complexity of flower and ecological strategies. The evolution in orchid floral morphology, structure, and physiological properties has held the fascination of botanists for centuries, from Darwin through to the present. In floral studies, MADS-box genes contributing to the now famous ABCDE model of floral organ identity control have dominated conceptual thinking. The sophisticated orchid floral organization offers an opportunity to discover new variant genes and different levels of complexity to the ABCDE model. Recently, several remarkable research reports on orchid MADS-box genes, especially B-class MADS-box genes, have revealed the evolutionary track and important functions on orchid floral development. Diversification and fixation of both paleoAP3 gene sequences and expression profiles might be explained by subfunctionalization and even neofunctionalization. Knowledge about MADS-box genes encoding ABCDE functions in orchids will give insights into the highly evolved floral morphogenetic networks of orchids.
