Analysis of speciation process in Liliaceae sensu lato

报道了百合亚科部分成员生活史特征的比较研究结果，并用matK进行了分子系统分析。叶绿体基因和核糖体DNA(ITS)的内部转录间隔区。在分析百合及其近缘类群的属间和属下亲缘关系时，测定了百合、野百合、假丝酵母、野百合和贝母的matK基因及其区域的序列，并以白刺属和维州贝母为外类群。Nomocharis种是百合属的类群。Notholirion、心脏分泌物和贝母被证明是百合的姐妹群。结果表明，百合近缘类群之间的系统发育关系有许多新的证据，百合属和心叶百合属均为单果植物，开花时间从8年到10年或更长时间。百合属Lilium mculatumSensu Lato Coni…较多的有两个亚种，L亚种。斑藻Thunb.和亚种。Dauricum(Ker-Gawl.)哈拉。然而，我最近的研究表明，这两个亚种是不同的两个物种，原因如下。1)形态：麦冬地上部茎上具糙硬毛，发芽；达乌里地龙茎上无毛，地下萌发。2)生活史：黑麦草为上位型植物(HETP)，蝙蝠葛根为上位型植物(ETP)。3)染色体：无核仁收缩，而达乌里乳杆菌核仁收缩频率较高(Noda，1987)。4)分子数据：不同物种的rDNA matK基因及其ITS序列模式不同。南欧特有的球茎乳杆菌是从蝙蝠葛根霉中分离出来的，在日本的一个特有种中分裂为多倍体乳杆菌，是二倍体和三倍体的复合种。三倍体叶连翘植株含有部分连翘叶连翘基因组。马科维奇兹。洋葱属具有弧形-第三纪元素的植物以扁平叶为特征。在目前的分析中，这种形态特征没有反映出系统发育的制约因素。较少

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
