蝽科精巢细胞减数分裂染色体行为及其反映的属种间亲缘关系
Chromosome behaviors of testis cells and the implied genetic relationship among the observed genera and species in Pentatomidae (Hemiptera:Pentatomidae)
摘要
Abstract
In order to explore the difference in chromosome morphology and behavior at different phases in the process of meiosis of testis cells, genetic relationship among genera and species, and evolutionary law in Pentatomidae, we observed the chromosome morphology and behaviors and the formation of sperms of testis cells of 9 species belonging to 6 genera of Pentatomidae by using conventional chromosome preparation. The results showed that testis cells of Pentatomidae are " 0" -type during the meiosis. The chromosomes of testis cells of Pentatomidae are similar in behavior but different in morphology. The arrangement and relative length of chromosomes, the karyotype and the sperm characteristics are different among genera and species. The average relative length of chromosome sets of the observed species in Pentatomidae is all 12.5. The amount information of chromosome set length of testis cell of Pentatomidae is constant in the evolutionary process. Eurydema, Aelia, Rubiconia and Graphosoma display a close genetic relationship, while Stollia and Carpocoris are more closely related based on the cluster analysis of chromosome relative length of the observed species.关键词
