摘要:

为了解蓝身大斑石斑鱼(Epinephelus tukula)的细胞生物学特征, 作者采用体内注射PHA培养肾细胞法对蓝身大斑石斑鱼染色体核型进行了研究。结果表明, 其染色体核型为2n=48t, 属于石斑鱼属鱼类典型的高位类中原始类群, 是石斑鱼属进化过程中出现较早的物种。

Abstract:

This study aims to assess the cell biological characteristics of Epinephelus tukula. We analyzed the karyotype of E. tukula from their renal tissue using the PHA and colchicine injection methods. The results revealed 48 telocentric chromosomes in the diploid number, and their karyotypic formula was 2n = 48t. The study deduces that E. tukula comprises the characteristics representative of the ancestral karyotypic pattern and belongs to the primitive groups.

Key words: Epinephelus tukula karyotype chromosome
