中国丝盖伞属裂盖组的三个新种

丝盖伞属裂盖组Inocybe sect.

Two distinct endogenous type C viruses isolated from the asian rodent Mus cervicolor: conservation of virogene sequences in related rodent species.

The cocultivation of a lung cell line from the Southeast Asian mouse Mus cervicolor with cells from heterologous species has resulted in the isolation of two new distinct type C viruses. Both viruses are endogenous to M. cervicolor and are present in multiple copies in the cellular DNA of these mice. One of the viruses, designated M. cervicolor type CI, replicates readily in the SIRC rabbit cell line and is antigenically related to the infectious primate type C viruses isolated from a woolly monkey (simian sarcoma-associated virus) and gibbon apes (gibbon ape leukemia virus). This virus is also closely related by both immunological and nucleic acid hybridization criteria to a type C virus previously isolated from a second Asian murine species, Mus caroli. The isolation of the M. cervicolor type C I virus thus provides further evidence that the infectious primate type C viruses originated by trans-species infection of primates by an endogenous virus of mice. The second virus, designated M. cervicolor type C II, replicates well in various cell lines derived from the laboratory mouse Mus musculus. While antigenically related to type C viruses derived from M. musculus, the M. cervicolor type C II virus isolate can be readily distinguished from standard murine leukemia viruses. Both new type C viruses from M. cervicolor are unrelated to the previously described retrovirus (M432) isolated from the same Mus species. The DNA of M. cervicolor therefore contains multiple copies of at least three distinct classes of endogenous viral genes. An examination of the cellular DNA of other rodent species for nucleic acid sequences related to the genomes of both M. cervicolor type C I and II reveals that both viruses have been highly conserved evolutionarily, and that other species of rodents, such as laboratory mice and rats, contain endogenous virogenes related to those in the DNA of M. cervicolor.

Taxonomic synopsis of Hippophae (Elaeagnaceae)

The small genus Hippophae (Elaeagnaceae) was thoroughly revised by Rousi in 1971. Several systematic treatments have since then confused the concept. Recent reports from China have added new subspecies, taxa with possible hybrid origin, and invalidly published names. Phylogenetic work on morphology and molecular markers agrees to Rousi's view of terminal taxa and seven species are currently recognised. Hippophae rhamnoides is a highly variable species and circumscribes eight subspecies. Recent work also confirms hybrid origins of two Chinese taxa. The purpose of this paper is to present a taxonomic synopsis of the genus with all currently accepted taxa and known types, especially in a situation of growing economic interest in Hippophae. We also provide a key and a map of the generic distribution.

中国沙塘鳢属鱼类线粒体12S rRNA基因序列分析

沙塘鳢属鱼类为东亚特有的小型淡水经济鱼类,中国产沙塘鳢属鱼类分类问题长期存在争议。本文测定了中国产沙塘鳢属鱼类全部种类的线粒体12S rRNA基因部分序列,结合GenBank中下载的2种日本沙塘鳢属鱼类和塘鳢科鱼类同源序列,探讨中国产4种沙塘鳢属鱼类的物种有效性,分析沙塘鳢属鱼类的系统发育关系。作者所使用的同源序列长度为690bp,其中变异位点258个,简约信息位点201个,包括插入/缺失位点34个,转换/颠换平均值为3.0,表明12S rRNA基因是研究沙塘鳢属鱼类系统发育关系的合适分子标记。基于p-distance模型的6种沙塘鳢属鱼类种内遗传距离为0.000—0.024,种间遗传距离为0.058—0.064,支持暗色沙塘鳢和中华沙塘鳢为不同种,中国产沙塘鳢属鱼类包括中华沙塘鳢、河川沙塘鳢、海丰沙塘鳢、鸭绿江沙塘鳢4个种的观点;至于中国还有没有新的沙塘鳢属鱼类,尚有待进一步研究。系统发育分析表明海丰海塘鳢是河川沙塘鳢的姐妹群,暗色沙塘鳢与O.hikimius的亲缘关系最为密切,而同属其余类群之间的系统发育关系则由于自展数据支持率较低而尚不明确。中国产沙塘鳢和日本产沙塘鳢并未单独分群,推测沙塘鳢属鱼类的共同原始祖先可能广泛分布于中国、朝鲜和日本等东亚地区,约在4.9—6.5百万年前的上新世开始分化,系统发育过程比较适合离散假说。
