| 中文摘要: |
| 采用胸腔注射植物血球凝集素(phytohemagglutinin,PHA)及秋水仙素溶液,取活体头肾细胞经低渗、固定、空气干燥法,分析比较了中华单角鲀(Monacanthus chinensis)、黄鳍东方鲀(Takifuguxanthopterus)、红鳍东方鲀(T.rubripes)的核型。结果表明,3种海水鱼中期染色体均为二倍体,未发现异型性染色体、随体和次缢痕。其核型如下:中华单角鲀的核型为2n=34(34t),臂数:NF=34;黄鳍东方鲀的核型为2n=44(12m+8sm+24t),臂数:NF=64;红鳍东方鲀的核型为2n=44(14m+6sm+24t),臂数:NF=64。中华单角鲀的核型与后两者存在较大差异。同时,将此3种鱼的核型与前人报道的其他鲀形目鱼类核型作了比较。 |
| 英文摘要: |
| The karyotypes of three species of Tetraodontiformes fishes were analyzed. The PHA and colchicine were injected in vivo,and kidney cells were collected and treated with lower osmotic pressure and air-drying technique. The results showed that these three marine species had diploid chromosome karyotypes,and all did not contain satellite chromosome,secondary constrictions and sex chromosome. The karyotype formula were as follows: the karyotype of Monacanthus chinensis was 2n = 34,34t,NF = 34; the karyotype of Takifugu xanthopterus was 2n = 44,12m + 8sm + 24t,NF = 64; and the karyotype of T. rubripes was 2n = 44,14m + 6sm + 24t,NF = 64; We also compared the karyotypes of the related fishes in the order of Tetraodontiformes. |
