2Out of Africa: Miocene Dispersal, Vicariance, and Extinction within Hyacinthaceae Subfamily Urgineoideae显示文摘Disjunct distribution patterns in plant lineages are usually explained according to three hypotheses:vicariance,geodispersal,and long distance dispersal.The role of these hypotheses is tested in Urgineoideae(Hyacinthaceae),a subfamily disjunctly distributed in Africa,Madagascar,India,and the Mediterranean region.The potential ancestral range,dispersal routes,and factors responsible for the current distribution in Urgineoideae are investigated using divergence time estimations.Urgineoideae originated in Southern Africa approximately 48.9 Mya.Two independent dispersal events in the Western Mediterranean region possibly occurred during Early Oligocene and Miocene(29.9–8.5 Mya)via Eastern and Northwestern Africa.A dispersal from Northwestern Africa to India could have occurred between 16.3and 7.6 Mya.Vicariance and extinction events occurred approximately 21.6 Mya.Colonization of Madagascar occurred between 30.6 and 16.6 Mya,after a single transoceanic dispersal event from Southern Africa.The current disjunct distributions of Urgineoideae are not satisfactorily explained by Gondwana fragmentation or dispersal via boreotropical forests,due to the younger divergence time estimates.The attened winged seeds of Urgineoideae could have played an important role in long distance dispersal by strong winds and big storms,whereas geodispersal could have also occurred from Southern Africa to Asia and the Mediterranean region via the so called arid and high altitude corridors.Syed Shujait Ali Martin Pfosser Wolfgang Wetschnig Mario Martínez Azorín Manuel B.Crespo Yan Yu 2013Journal of Integrative Plant Biology2013,55,10:0
3Molecular phylogenetics of subfamily Urgineoideae(Hyacinthaceae):Toward a coherent generic circumscription informed by molecular,morphological,and distributional data显示文摘The taxonomy and systematics of Urgineoideae(Hyacinthaceae)have been controversial in recent decades,with contrasting taxonomic treatments proposed based on preliminary and partial studies that have focused on morphology and/or solely plastid DNA sequence data.Some authors have recognized only two genera,with a very broadly conceived Drimia,while others have accepted several genera that,although better defined morphologically,were doubtfully monophyletic.Here,we present phylogenetic analyses involving four plastid DNA regions(trnL intron,trnL-F spacer,matK,and the trnCGCA-ycf6 intergenic region),a nuclear region(Agt1),and a selection of 40 morphological characters.Our study covers 293 samples and ca.160 species of Urgineoideae(ca.80%of its global diversity).Bayesian inference,maximum likelihood,and maximum parsimony analyses were performed to derive the phylogenetic patterns.The combination of data yielded phylogenetic trees with 31 well-defined clades or lineages,most corresponding to previously described genera,although some have required description or revised circumscription.As with other monocot families,a considerable degree of homoplasy was observed in morphological characters,especially in those groups with unspecialized flowers;nonetheless,consistent syndromes of traditional and novel characters are shown to support clade recognition at genus rank.The forthcoming revised classification of Urgineoideae is outlined here.Mario Martínez-Azorín Manuel BCrespo MaríaÁngeles Alonso-Vargas Michael Pinter Neil RCrouch Anthony PDold Ladislav Mucina Martin Pfosser Wolfgang Wetschnig 2023Journal of Systematics and Evolution2023,61,1:0
