Abstract
It is unclear whether gene regulatory changes that drive evolution at the population and species levels [1-3] can be extrapolated to higher taxonomic levels. Here, we investigated the role of cis-regulatory changes in fruit evolution within the Brassicaceae family. REPLUMLESS (RPL, At5g02030) controls development of the replum, a structure with an important role in fruit opening and seed dispersal [6]. We show that reduced repla resembling the Arabidopsis rpl mutant correlated across the Brassicaceae with a point mutation in a conserved cis-element of RPL. When introduced in Arabidopsis, this nucleotide change specifically reduced RPL expression and function in the fruit. Conversely, Brassica RPL containing the Arabidopsis version of the cis-element was sufficient to convert the Brassica replum to an Arabidopsis-like morphology. A mutation in the same nucleotide position of the same cis-element in a RPL ortholog has been independently selected to reduce seed dispersal during domestication of rice, in spite of its very different fruit anatomy. Thus, single-nucleotide regulatory mutations at the same position explain developmental variation in seed-dispersal structures at the population and family levels and suggest that the same genetic toolkit is relevant to domestication and natural evolution in widely diverged species.
