论文摘要: Various genes have been screened on extra chromosomes, but their molecular characterization, expression pattern and biological function are still unclear. Here, we utilized a male-specific sequence of polyploid gibel carp (Carassius gibelio) to identify a novel male-specific SET (Su(var) 3-9, Enhancerof- zeste, Trithorax) domain-containing gene setdm on extra microchromosomes of gibel carp males. And setdm was characterized in molecule and expression aspects, in which its expression was specific to testis, and had relative high transcription during middle/late stages of testis development. Moreover, prominent expression of Setdm in spermatogenic cells was observed in testis through immunofluorescence co-localization analysis. These results suggest that biological function of setdm might be related to testis development and spermatogenesis of gibel carp. Additionally, the homeologous gene setdmf of setdm, was also characterized, and its expression was gonad-specific, in which its expressed product was detected to mainly distribute in gametogenic cells of testis and ovary, and to have dynamic expression pattern similar to that of setdm. Based on the current results, we propose that the novel male-specific setdm on extra microchromosomes might be functional divergence gene of the gonad-specific setdmf. Therefore, these findings will help us to further understand evolutionary fate and functional role of genes on extra microchromosomes. (C) 2017 Science China Press.
