Duplication is a prominent feature of plant genomic architecture. This has led many
researchers to speculate that gene duplication may have played an important role in the
evolution of phenotypic novelty within plants. Until recently, however, it was difficult to make
this connection. We are now beginning to understand how duplication has contributed to
adaptive evolution in plants. In this review we introduce the sources of gene duplication and
predictions of the various fates of duplicates. We also highlight several recent and pertinent …
