  1. 3 the comparison of mitochondrial genomes and phylogentic relationships of amphibian there still is a lack of consensus regarding living amphibian phylogenetic relationships. the most widely accepted hypothesis, based on morphological data, supports the monophyletic origin in the late paleozoic ( 300 mya ) of the three living orders in the class amphibia and a sister - group relationship between caudata and anura ( the batrachia hypothesis ) to the exclusion of the gymnophiona

    3兩棲類動物的線粒體基因組結構比較和系統發生關系現存兩棲類的三個目的系統發生關系仍然沒有統一意見，最廣泛被接受的假說，是建立在形態學證據基礎上，支持現生的兩棲類三個目在古生代後期（ 300mya ）單系起源，並且無尾類和有尾類為姐妹群關系（蛙類假說） 。
  2. Robustness of our results was confirmed by high bootstrap support of all nodes in the trees. this result contradicts the batrachia hypothesis ( a salamander + frog grouping ), and is consistent with bolt ' s hypothesis ( 1991 ) basing on the morphological data. the result was also supported by previous molecular studies based on mitochondrial and nuclear rrna data

    這個結果與蛙類假說是相矛盾的，與bolt （ 1991 ）中國澤蛙線粒體基因組結構及種群系統地理學研究在形態學基礎上提出的絨蝶類和蚓螺類為姐妹群關系的假說相一致，並得到建立在線粒體和核trna基因數據基礎上的許多分子研究的支持。
  3. The complete nucleotide sequence of the mitochondrial genome of f. limnocharis was detailedly compared with those of 5 other amphibians. the nucleotide sequences of 22 trna encoded by 6 amphibians mitochondrial genomes were combined and aligned to the homologous sequences of the 11 veterbrate taxa. using teleosts as outgroup, the phylogenetic analyses results show that mp, nj and ml trees all strongly support the monophyly of living amphibians with respect to other living tetrapods and favor a sister group relationship for caecilians and salamanders

    我們在測定了澤蛙線粒體全基因組序列的基礎上，與已知其它的5種兩棲類進行詳細的比較分析，同時選擇了11種高等脊椎動物的線粒體全基因序列，以硬骨魚類做外群，用22個trna基因合併數據進行系統發生重建分析，結果表明mp 、 nj和ml樹都強力地支持現生兩棲類動物為單系群並且蠑螈類和蚓螈類為姐妹群關系（自引導值分別為92 、 99 、 100 ） 。
  4. The results show that ( 1 ) loops are in general more variable than stems, and in loops a strong adenine bias are observed : ( 2 ) there does not exist a saturation effect in stems, loops or all positions of the 16s rrna gene fragments : ( 3 ) in the molecular cladogram, bagarius forms a sister group with glyptothorax, and euchiloganis forms a sister group with pareuchiloglanis, and exostoma forms a sister group with glyptosternum : ( 4 ) the phlogenetic positions of pseudecheneis, exostoma and glyptosternum are not recognized ; the glyptosternoid fishes are not monophyly although they are defined by 13 osteological apomorphies ; the incongruence of cladograms between molecular and morphological sets may be caused by less informative sites of the 550 homologous sites ; ( 5 ) e. davidi and e. kishinouyei could be the same species according to the genetic distances ; p. sinensis and p. anteanalis could be too

    結果表明： （ 1 ）環區平均變異位點較莖區多，有很強的a偏好性； （ 2 ）沒有替代飽和現象； （ 3 ）分子系統樹上?屬和紋胸?屬構成姐妹群，石爬?屬和?屬構成姐妹群， ?屬和原?屬構成姐妹群； （ 4 ） ?屬、原?屬和褶?屬的系統發育位置不定， ? ?魚類並未形成一個單系類群；可能的原因是所得到的16srrna基因片段信息位點太少； （ 5 ）青石爬?和黃石爬?可能是同一物種，中華?和前臀?可能是同一物種。
  5. 2. 5 ul of 10 x reaction buffer, 1. 5 ul 25mm mgcl2, 0. 3 ul lomm dntp, 0. 5 ul taqdna polymerase ( 5 u / ul ), and lul ( = 20ng ) of primer were used in per reaction. each reaction was overlaid with one drop of paraffin oil. the initial denaturation step was used at 94 for 1 min 45 sec ; then denatured at 94 for 30 sec, annealed at 37 1 min, extended at iv b 72 for 2 min and repeated the cycle 45 times, at last, extended at 72 ' c for lomin

    等（ 1995 ）利用rapd標記區分美國東部一雜交地帶的蟋蟀的兩個姐妹種， allonemobiusfasciatus和a . socius ，並於1998年使用rapd和異型酶標ic做出了這兩種蟋蟀的基因連鎖圖；國內田英芳、鄭哲民（ 20of ）首次將rapd技術運用於蟋蟀總科的分子系統學研究中，採用2種引物對7種蟋蟀進行了基困組dna多態性研究，並應用upg問a法構建樹狀圖，椎測系統發生關系
  6. But the interrelationships among these genera remain uncertain until now. a great quantity of features recognized in dromaeosaurids supports the view that dromaeosauridae is the sister group of avialae

    目前關于奔龍類在手盜龍類中的系統位置有幾種不同的觀點，本文支持奔龍類與avialae的關系最為密切的觀點，即奔龍類是與avialae最為親近的類群，兩者構成姐妹群關系。
  7. But there is ambiguously taxonomic position between chaitophoridae and aphidinae. the genetic distance of aphididae and macrosiphinae in aphididae is more diverged than that of between chaitophoridae and aphididae. the 600bp - 1700bp region of issrdna gene maybe unsuitable to aphididae, it includes a helix e21

    1數據分析軟體中構建的upgma 、 nj 、 me和mp分子系統樹一致支持群蚜科和毛管蚜科形成一單系群，這二者相聚后與刺蚜亞科互為姐妹群。
