Analysis of speciation process in Liliaceae sensu lato

本文报道了丁香属植物生活史特征的比较研究结果，并用分子标记进行了分子系统分析。叶绿体基因和核糖体DNA（ITS）内部转录间隔区。为分析百合及其近缘类群的属间和属下关系，以日本赤藓属（Erythronium japoniicum）和Medeola virginana为外群类群，对百合、Nomocharis、Candiocrimun、Notholirion和贝母进行了matK基因和ITS区域的测序。Nomocharis属属于百合属的类群。Notholirion， Cardiocrinum和贝母被证明是百合的姐妹类群。本研究结果为莲属亲缘分类群之间的系统发育关系提供了许多新的证据，Notholirion属和Cardiocrinum属为单果植物，开花时间从8年到10年不等，甚至更长。白百合（Lilium mculatum sensu lato conto）。欧了。和无性系种群。dauricum(百合)。Hara。然而，我最近的研究发现，这两个亚种是不同的两个物种，有以下四个原因。1)形态学;在地面以上的茎上有糙硬毛，并显示上胚芽；茎上无毛，显示下胚芽。2)生活史;白莲属水仙型植物（HETP），金莲属水仙型植物（ETP）。3)染色体：无核仁缩窄，但高频率有核仁缩窄（Noda 1987）。4)分子数据：这些物种在rDNA的matK基因和ITS序列模式上存在差异。欧洲南部特有的黄乳草是从日本特有种黄乳草中分离出来的。Lancifolium是二倍体和三倍体复合体。三倍体植物中含有莱希特兰变种的部分基因组。葱属植物具有近三级元素，其特点是叶片扁平。这种形态特征在本分析中没有反映出系统发育的限制。少

The results of comparative studies on the life history characteeristics of selected members of Lileae are reported along with molecular systematic analysis using the matK. of chloroplast genes genes and the internal transcribed spacer region of nuclear ribosomal DNA(ITS). In analyzing the inter-and infra-generic relationships in Lilium and allied taxa, the matK gene and ITS region were sequmenced for Lilium, Nomocharis, Candiocrimun, Notholirion, and Fritillaria species, with Erythronium japoniicum and Medeola virginiana used as outgroup taxa. The Nomocharis species were ingroup taxa of the genus Liliurn. Notholirion, Cardiocrinum, and Fritillaria were demonstrated to be sister groups to Lilium. The present results have shown many new evidence concerning the phylogenetic relationships among the Lilian allied taxa, Genus Notholirion and Cardiocrinum were monocarpic plants and flowering time of these plants took from 8 years 10 to years or more over years.Lilium mculatum sensu lato consi … More sts of two subspecies, L mculatum subsp. maculatum Thunb. and subsp. dauricum(Ker-Gawl.) Hara. However, my recent studies revealed that these two subspecies are different two species with the follwing four reasons. 1)Morphology; L. mculatum has hispid hair on the stem above the ground, and shows epigeal germination; L. dauricum no hair on the stem and shows hypogeal germination. 2)Life history; L. mculatum is a hyo-epigeous type plant(HETP), while L. dauricum is epigeous type plant(ETP). 3)Chromosomes: L. mculatum has no nucleolar constrictions but L. dauricum has nucleolar constrictions in high frequency (Noda 1987.) 4) Moleculer data: these species are different in the sequence patterns of matK gene and ITS of rDNA. The South Europe endemic L. bulbiferum sparated from L. dauricum and after divided to L. mculatum of a endemic species in JapanL.lancifolium was diploid and triploid complex species. Triploid plants of L.lancifoliumcontained a part of genom of L.leichtlinii var. maximowiczii. The plants of having Arcto-Tertiary element in genus Allium is characterized by having flat leaf. This morpholpgical character was not refrected the phylogenetic constraints in the present analysis. Less
