Tuesday Morning Contributed Talks Vision, TJ [1]. Genomics in Mimulus (Phrymaceae), a model for evolutionary genetics. THE genus Mimulus (Phrymaceae, Lamiales) has been a model plant system for ecological and evolutionary genetics for over half a century because of its striking ecological and phenotypic diversity and tractability as an experimental organism. Most of the ~160 species are part of two large radiations centered in western North America and Australia. Mimulus occupies habitats from desert to aquatic to alpine, includes annual, herbaceous perennial and woody perennial growth forms, and contains both diploid and polyploid taxa. Reproductive traits and pollination systems are particularly diverse, and mating systems range from completely outcrossing to obligately selfing and even obligately asexual. A multi-institutional consortium is currently developing genomic resources for Mimulus including ESTs, gene-based markers, permanent mapping populations, high-density genetic maps, BAC-based physical maps, and a whole genome shotgun sequence from M. guttatus (2n = 28, ~500 Mb). These genomic tools are being applied to study reproductive isolation in the wild, including habitat specialization, floral divergence, and the fertility of hybrids. Because of its phylogenetic position, Mimulus also serves as a useful point of comparison for genome studies in the Solanaceae.
