SHAW<\/p>\n<h3>Abstract<\/h3>\n<div>\n<p>The monoicous peatmoss <em>Sphagnum subnitens<\/em> has a tripartite distribution that includes disjunct population systems  in Europe (including the Azores), northwestern North America and New  Zealand. Regional genetic diversity was highest in European <em>S.\u00a0subnitens<\/em> but in northwestern North America, a single microsatellite-based  multilocus haploid genotype was detected across 16 sites ranging from  Coos County, Oregon, to Kavalga Island in the Western Aleutians (a  distance of some 4115\u00a0km). Two multilocus haploid genotypes were  detected across 14 sites on South Island, New Zealand. The  microsatellite-based regional genetic diversity detected in New Zealand  and North American <em>S.\u00a0subnitens<\/em> is the lowest reported for any <em>Sphagnum<\/em>.  The low genetic diversity detected in both of these regions most likely  resulted from a founder event associated with vegetative propagation  and complete selfing, with one founding haploid plant in northwest North  America and two in New Zealand. Thus, one plant appears to have  contributed 100% of the gene pool for the population systems of <em>S.\u00a0subnitens<\/em> occurring in northwest North America, and this is arguably the most  genetically uniform group of plants having a widespread distribution yet  detected. Although having a distribution spanning 12.5\u00b0 of latitude and  56\u00b0 of longitude, there was no evidence of any genetic diversification  in <em>S. subnitens<\/em> in northwest North America. No genetic structure was detected among the three regions, and it appears that European plants of <em>S.\u00a0subnitens<\/em> provided the source for New Zealand and northwest North American populations.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>An article published in Molecular Biology presents a unique report on Sphagnum in North America.\u00a0 Details appear in BBC Earth News and the journal article information is presented below: One haploid parent contributes 100% of the gene pool for a &hellip; <a href=\"https:\/\/blogs.nwic.edu\/bryoblog\/2011\/03\/30\/%e2%80%a6-arguably-the-most-genetically-uniform-group-of-plants-having-a-widespread-distribution-yet-detected\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":172,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[8156,8155,8154],"class_list":["post-769","post","type-post","status-publish","format-standard","hentry","category-uncategorized","tag-clone","tag-peatmoss","tag-sphagnum-subnitens"],"_links":{"self":[{"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/posts\/769","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/users\/172"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/comments?post=769"}],"version-history":[{"count":0,"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/posts\/769\/revisions"}],"wp:attachment":[{"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/media?parent=769"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/categories?post=769"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.nwic.edu\/bryoblog\/wp-json\/wp\/v2\/tags?post=769"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
