          Abstract

          Premise

          Rosebay willowherb, or fireweed ( Chamerion angustifolium: Onagraceae), has diploid, tetraploid, and hexaploid cytotypes. There are known physiological and ecological differences among the three cytotypes, but genetic differences remain undetermined. We developed simple sequence repeat (SSR) markers for this species.

          Methods and Results

          Leaf samples were collected from three hexaploid C. angustifolium populations. We successfully amplified 16 SSR loci, which were found to be highly polymorphic. The number of alleles, the observed heterozygosity levels, and the expected heterozygosity levels ranged from four to 13, 0.286–0.899, and 0.372–0.871, respectively. Most primers could also be amplified successfully in C. conspersum and the closely related species Epilobium palustre.

          Conclusions

          The 16 polymorphic SSR markers developed here will be useful for genetic studies in C. angustifolium and related species.

              Efficient Exact Maximum a Posteriori Computation for Bayesian SNP Genotyping in Polyploids

              The problem of genotyping polyploids is extremely important for the creation of genetic maps and assembly of complex plant genomes. Despite its significance, polyploid genotyping still remains largely unsolved and suffers from a lack of statistical formality. In this paper a graphical Bayesian model for SNP genotyping data is introduced. This model can infer genotypes even when the ploidy of the population is unknown. We also introduce an algorithm for finding the exact maximum a posteriori genotype configuration with this model. This algorithm is implemented in a freely available web-based software package SuperMASSA. We demonstrate the utility, efficiency, and flexibility of the model and algorithm by applying them to two different platforms, each of which is applied to a polyploid data set: Illumina GoldenGate data from potato and Sequenom MassARRAY data from sugarcane. Our method achieves state-of-the-art performance on both data sets and can be trivially adapted to use models that utilize prior information about any platform or species.
