Plant MADS-box genes form a large gene family for transcription
factors and are involved in various aspects of developmental
processes, including flower development. They are known to be
subject to birth-and-death evolution, but the detailed features of
this mode of evolution remain unclear. To have a deeper insight
into the evolutionary pattern of this gene family, we enumerated
all available functional and nonfunctional (pseudogene) MADS-
box genes from the Arabidopsis and rice genomes. Plant MADS-
