Here, we applied traditional population genetic analyses to unravel the phylogeographical relationships among invasive (North American) and native (North African, Mediterranean region, and Eurasian) range populations of\u00a0<em class=\"EmphasisTypeItalic \">Brassica nigra<\/em>\u00a0using chloroplast DNA. We sequenced chloroplast DNA intron (<em class=\"EmphasisTypeItalic \">trnF<\/em>\u2013<em class=\"EmphasisTypeItalic \">trnL<\/em>) for 284 individuals representing 36 native and 15 invasive range populations of\u00a0<em class=\"EmphasisTypeItalic \">B. nigra<\/em>. Thirty-two haplotypes were found over the whole data set. A similarity between the invasive range and native range populations in genetic diversity combined with results from analyses of molecular variance and gene genealogies suggest that invasive\u00a0<em class=\"EmphasisTypeItalic \">B. nigra<\/em>\u00a0populations were introduced from multiple sources in the native range. More generally, this study adds to the growing body of data on the genetic patterns involved in biological invasions that is crucial to our understanding of the evolutionary trajectories of invasive populations<\/p>\n<p>&nbsp;<\/p>\n<p>More info:<\/p>\n<p>Oduor AMO, Herrador MB, G\u00f3mez JM, Perfectti F. 2015<br \/>\nInvasion of\u00a0<em>Brassica nigra<\/em>\u00a0in North America: distributions and origins of chloroplast DNA haplotypes suggest multiple introductions<br \/>\n<strong>Biological Invasions 17: 2447-2459<\/strong><br \/>\n<a href=\"http:\/\/dx.doi.org\/10.1007\/s10530-015-0888-1\" target=\"_blank\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-96\" src=\"http:\/\/wdb.ugr.es\/~fperfect\/wp-content\/uploads\/DOI.png\" alt=\"DOI\" width=\"32\" height=\"16\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<pre><a href=\"https:\/\/www.flickr.com\/photos\/amayu\/8911961\">Featured image<\/a> by\u00a0<a class=\"owner-name truncate\" title=\"Ir a la galer\u00eda de Jill Siegrist\" href=\"https:\/\/www.flickr.com\/photos\/amayu\/\" data-track=\"attributionNameClick\" data-rapid_p=\"28\">Jill Siegrist<\/a> (CC BY-NC-SA 2.0)<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>We suggest that invasive\u00a0B. nigra\u00a0populations were introduced in North America from multiple sources in the native range. &nbsp;<\/p>\n","protected":false},"author":1,"featured_media":257,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0},"categories":[6,3],"tags":[26,25,4],"_links":{"self":[{"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/posts\/256"}],"collection":[{"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/comments?post=256"}],"version-history":[{"count":3,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/posts\/256\/revisions"}],"predecessor-version":[{"id":261,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/posts\/256\/revisions\/261"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/media\/257"}],"wp:attachment":[{"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/media?parent=256"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/categories?post=256"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wpd.ugr.es\/~fperfect\/index.php\/wp-json\/wp\/v2\/tags?post=256"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
