  dna data
Bikinia occurs either as paraphyletic with Tetraberlinia (chloroplast DNA data) or as a monophyletic group that also includes the new monotypic genus Icuria sister to Tetraberlinia (ITS data).
      
A method to reveal hybrids by comparing their placement in cladograms based on morphological or on chloroplast DNA data, respectively, is presented.
      
One important recommendation is made: all phylogenetic analyses of chloroplast DNA data should be accompanied by a data matrix and contain information on how the matrix was compiled.
      
This lack of resolution does not appear to result from insufficient or inappropriate DNA data, nor is it caused by inadequate sampling of taxa.

The analysis of nucleotide sequence variation has proven extremely useful in the reconstruction of plant phylogenetic relationships. In this paper 9 a general review of the methods of molecular systematic of plant at DNA level has been made. The progresses of RFLP analysis and the applications of PCR in this field were introduced. The phylogenetic analysis and testing methods using DNA data were especially discussed.

本文简要总结了近年来在DNA水平上的植物系统学研究方法,着重介绍了限制性长度多态性分析,PCR技术在植物系统学上的应用等这一领域最新的进展,并对分子数据的分析方法及系统树的构建进行了详细讨论。

Genetic differentiation among three pine stem rust fungi from China,i.e., Cronartium ribicola, C.flaccidum and C.quercuum, was assessed by random amplified polymorphic DNA(RAPD). Ten isolates(including an outgroup isolate)with different host and/or geographical origins were subjected to study. Pairwise similarity analysis was conducted on 51 RAPD loci detected by five selected primers.

Genetic differentiation among three pine stem rust fungi from China,i.e., Cronartium ribicola, C.flaccidum and C.quercuum, was assessed by random amplified polymorphic DNA(RAPD). Ten isolates(including an outgroup isolate)with different host and/or geographical origins were subjected to study. Pairwise similarity analysis was conducted on 51 RAPD loci detected by five selected primers. The result shown that although there were intraspecific variations, three rust pathogens were clearly separated as distinctive groups, thus justifying these traditional fungal taxa by using DNA data. Genetic relatedness between C.ribicola and C.flaccidum was closer than that between C.quercuum and either of the former two,this being consistent with the relationship reflected by disease symptom and telial stage host range of these pathogens.High degree of intraspecific divergence was found between two C.flaccidum isolates which differ from each other in host specialization over their life circles, possibly demonstrating the genetic background underlying these two supposed formae speciales. Intraspecific variation was also found among C.quercuum isolates with different pine hosts, suggesting that the host specialization of C.quercuum in aceial stage as reported in Northern America may also exist in China. Evidences were also obtained that host adaptation,rather than geographic factors, is the primary force to drive genetic differentiation of the pine stem rust fungi.

用RAPD手段分析了我国3种松干锈菌Cronartiumribicola、C.flaccidum及C.quercuum在DNA水平上的遗传分化。用5个随机引物从10个菌株(含1个不同属参照菌株)中检测出51个多态DNA片段进行聚类分析,3种锈菌清晰地显示为不同类群,此结果为传统分类的成立提供了分子遗传学证据。3种锈菌中C.ribicola和C.flacidum的亲缘关系较近,这同由症状和冬孢子寄主反映出的相似关系一致。种内菌株间存在遗传差异,但其程度小于种间差异。锈孢子及冬孢子寄主都不同的C.flacidum菌株间差异明显,可能反映着专化型分化的遗传学基础。不同松树寄主的C.quercuum菌株间也存在差异,暗示我国的C.quercuum同北美一样存在对松类的寄生专化性分化。研究结果还提示松干锈菌的遗传分化主要同寄主有关,而与地理分布关系不大。

The Liaodong oak (Quercus Liaotungensis Koidz.) is a close relative of the Mongolia oak ( Q.mongolica Fisch.) which were separated by some morphological characters,such as the number of leaf lobes and the squamate form of cupula. Recently some authors observed that morphological diversity made the Liaodong oak unable to separate clearly from the Mongolia one,therefore,plant materials have been collected from Maoer Mountain of Heilongjiang province as a typical Q.mongolica population,and from Guandi...

The Liaodong oak (Quercus Liaotungensis Koidz.) is a close relative of the Mongolia oak ( Q.mongolica Fisch.) which were separated by some morphological characters,such as the number of leaf lobes and the squamate form of cupula. Recently some authors observed that morphological diversity made the Liaodong oak unable to separate clearly from the Mongolia one,therefore,plant materials have been collected from Maoer Mountain of Heilongjiang province as a typical Q.mongolica population,and from Guandi Mountain of Shanxi Province which represented the typical Liaodong oak population to compare isozyme and DNA diversity between both species. The winter bud samples were also analysed from Dongling Mountain near Beijing City since Dongling population is an intermediate form between the Maoer population and the Guandi population morphologically. Statistics of 13 putative loci belonging to 5 enzymes showed a high level of diversity within all populations. The value of genetic distance among populations was low,and showed that the Dongling population genetically located at the middle of both typical species. DNA data also showed that both typical oak populations shared similar variation with the Dongling pooulation. Among 172 polymorphic RAPD and DAF loci, no population specific band has been found .A significant difference in frequency of amplified products existed in 26 loci. Except for 3 irregular ones,frequency distribution of 23 loci seems clinal. The Dongling population also genetically located at the middle of both flanking populations. It was worth to note that the OPD 08 434 was probably unique to the Dongling oak since its frequency in the Guandi population has been estimated up to 100% and decreased to 0 in the Maoer population. The Dongling population received this unique DNA from the Guandi population probably by introgression. The strong gene flow in both directions implied a long history of distributive continuity for both oak species. High levels of morphological ,isozymatic and DNA diversity supplied enough genetic basis for reconstruction of degraded oak ecosytems.

通过植物群落结构、壳斗、叶脉形态特征、同工酶及DNA等多方面调查与测定,分析了帽儿山的蒙古栎(QuercusmongolicaFisch.)和东灵山、关帝山的辽东栎(Q.liaotungensisKoidz.)的遗传分化及多样性。各种水平的研究一致说明:两种植物的遗传分化较小,东灵山种群是典型蒙古栎、辽东栎种群的中间类型。确切地说,从东北到山西组成一个地理渐变群,存在大范围、强大的双向基因流
