Premise of the study: Microsatellite or simple sequence repeat (SSR) markers were developed to investigate the influence of ecological factors on gene flow and spatial genetic structuring of the submerged plant Ranunculus bungei (Ranunculaceae), which is regarded as an important species for understanding how plants adapt to an aquatic environment. Methods and Results: Twenty‐two microsatellite loci were identified from an expressed sequence tag (EST) library. The number of alleles per locus ranged from one to five, and the expected heterozygosity varied from 0.0 to 0.5 in four Chinese populations of R. bungei . Fourteen loci were polymorphic and significantly deviated from Hardy–Weinberg equilibrium. All of the loci were found to be amplifiable in two other species of Ranunculus section Batrachium , and cross‐amplification in six riparian and aquatic species of Ranunculaceae was also partially successful. Conclusions: These novel EST‐SSR markers will be useful for ecological and evolutionary studies of R. bungei as well as related species.
