Diversification of Lupinus (Leguminosae) in the western New World: Derived evolution of perennial life history and colonization of montane habitats

Phylogenetic insights into Andean plant diversification

“…In Halenia, the colonization of the South American Andes from Central America occurred more recently (∼1 Ma), according to the estimates of von Hagen and Kadereit (2003). Similar timing and direction were estimated for Lupinus by Drummond (2008). Overall, these estimates would be in agreement with the ideas of Simpson (1983), who argued that colonizations of the Andean flora by Nearctic elements occurred gradually since the Middle Miocene, and the closing of the Panama gap had little effect on it.…”

Legume Crops Phylogeny and Genetic Diversity for Science and Breeding

“…The vast range of morphological variation (from tiny herbs to large trees) and ecological adaptation (from coastal sand dunes to montane forests) pose challenges for resolving phylogenetic relationships using taxonomic methods (Drummond et al, 2012). Comparisons of nuclear and chloroplast DNA sequences (Ainouche and Bayer, 1999;Wink and Mohamed, 2003;Ainouche et al, 2004;Ree et al, 2004;Drummond and Hamilton, 2007;Drummond, 2008;Eastwood et al, 2008b;Drummond et al, 2012) have made some progress toward resolving Lupinus phylogeny, but ambiguities still remain. Current efforts are underway to sample large gene sets obtained by whole transcriptome sequencing across New World Lupinus (C. Hughes, G. Atchison, D. Filatov, personal communication), which should definitively answer these remaining questions.…”

Development of microsatellite markers in Lupinus luteus (Fabaceae) and cross‐species amplification in other lupine species

“…Only six loci amplifi ed in L. mutabilis . The lower success rate for ampli fi ca tion in L. mutabilis vs. L. hispanicus might have been predicted given the close genetic relationship between L. luteus and L. hispanicus and the earlier divergence between New and Old World lupines ( Drummond, 2008 ). The low proportion of polymorphic SSR markers revealed low levels of genetic variation for L. luteus .…”

“…Lupinus luteus L. (Fabaceae) belongs to a large and diverse genus comprising more than 200 annual and perennial herbaceous species growing in a wide range of climatic and soil conditions ( Drummond, 2008 ). It is widely distributed across the Mediterranean region, but it is not clear how much of this range is native, and how much involves naturalization due to human cultivation (Petterson et al, 1998).…”
