Use of ISSR markers to assess small scale genetic variation of reed canarygrass (Phalaris arundinacea) in an Ohio wetland.
We are using ISSR markers to assess small scale genetic variation of the invasive reed canarygrass (Phalaris arundinacea) in a 121 hectare mixed wetland preserve in Richland County, Ohio. Approximately 12 hectares of this wetland was logged in the mid 1990ís, and this was followed by expansion of reed canary grass into a mostly monotypic stand. Small patches of reed canarygrass also exist in nearby unlogged swamp forest. The goal of this study is to assess the relative roles of establishment by seed vs. by rhizomatous spread in the recent expansion and to estimate the overall genetic diversity of reed canarygrass at this site. A pilot project sampled plants along a 120 meter linear transect, and significant genetic variation was revealed using ISSR markers. Variation for ISSR markers is being used to examine clonal diversity in the wetland and to compare the population with nearby populations.
