batrachian

Magainin is the skin secretion product of batrachia under the eriviroment pressure , which can be used to accelerate the fusion rate of wound and resist the infection . it can inhibit the growth of bacteria and fungus with the lowest concentration ; protegrin is isolated from porcine leukocyte hi 1993 and is useful as antiviral agents Magainins是爪蟾的皮膚在一定的環境壓力下分泌出的抗感染和促進傷口愈合的成分,低濃度便可抑制許多細菌和真菌生長; protegrin是1993年從豬的中性白細胞中分離得到,研究發現它具有抗愛滋病毒的功能。

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后期( 300mya )單系起源,并且無尾類和有尾類為姐妹群關系(蛙類假說) 。

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,并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。
