Higher level relationships remain unresolved, but supported groups do conflict with previous morphology-based hypotheses. Comparatively low levels of sequence divergence indicate that the use of more rapidly evolving regions will be required to resolve higher level relationships.

This has made it difficult to identify the phylogenetic root of the genus. In this study, we addressed this problem and characterized the early branching patterns within Iso{\"e}tes using an expanded set of taxa and three molecular markers. We assessed the saturation in the molecular data sets, tested for differences in evolutionary rate, determined the stability of the ingroup topology, and evaluated the applicability of the molecular clock. We then explored three alternative rooting approaches: outgroup, midpoint, and maximum likelihood under the assumption of a molecular clock. Attempts to infer the root of Iso{\"e}tes using the outgroup approach were severely hindered by the effects of saturation, but the results from midpoint rooting and the enforcement of the molecular clock were highly consistent among the data sets. We identify the root of Iso{\"e}tes to be located among three major, highly supported clades. {\textcopyright} Copyright 2006 by the American Society of Plant Taxonomists.},

Methods and Results: Using the Fast Isolation by AFLP of Sequences COntaining Repeats (FIASCO) protocol, nine microsatellite loci were isolated and characterized in 32 samples from four natural populations of I. hypsophila. The primers amplified di-and hexanucleotide repeats with three to 11 alleles per locus. Seven of nine primers were cross-amplified in I. sinensis with two to seven alleles per locus. Conclusion: The microsatellite loci primers will be useful for studies of genetic diversity and gene flow in natural populations of Isoetes species. {\textcopyright} 2012 Botanical Society of America.},
