The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.
刺鳅,属鲈形目、刺鳅科(Perciformes,Mastacembelidae),是广泛分布于中国南方的小型淡水鱼类。1998年,我室通过核型分析,首次发现该物种具有明显分化的异形性染色体,其性别决定类型为XX/XY型。1999年,本室通过染色体显带、精母细胞联会复合体观察,再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体,两者不仅已经出现结构异染色质分布上的不同,同时在外部形态上也存在明显差异,识别特征鲜明,在光镜观察下无需显带即能清晰辨认性染色体。

The excited-state intramolecular proton transfer tautomerism reaction of 6-methyl-4-hydroxy pyri-midine monomers and dimmers was investigated by the ab initio method with the self-consistent reaction field with Tomas's polarized continuum mode and CIS theories at HF level on the basis of 6-311+G* and 6-31G basis set. By studying the potential energy surface, it was found that the monomer's ground-state proton transfer process together with the excited-state proton transfer process is a molecular system of four energy level, but dimmers were not, which can be used to explain the fact that UV-visible absorption and fluorescence spectra of monomer and dimers all corresponded to quinoid.
采用 ab initio HF理论的组态相关CIS方法和连续溶剂模型PCM,分别在6-311+G*和6-31G水平上研究了6-甲基-4-羟基嘧啶单体及二聚体激发态质子转移的异构化反应;对其反应势能面的研究发现,单体基态和激发态的异构化反应一起可以形成四能级的分子电子体系,而二聚体的却不能,由此解释了单体和二聚体的紫外吸收光谱和荧光发射光谱均对应于酮式构型的原因。
