尕海孤雌生殖卤虫基因组的特异DNA片段

曾辉;陈成彬;刘凤岐;宋文芹;陈瑞阳

  Artemiais not only valuable for aquaculture but also exhibits unique biological characters. In this study, based on the silkwormBmdsxgene, a pair of primers was designed. After amplification with these primers, a DNA fragment Apdsx900 from parthenogenesisArtemiagenomic DNA was obtained. The following Southern blotting and FISH analysis also proved the fragment was specific for Gahai parthenogenesisArtemiagenome. To our knowledge, this is the first report of parthenogenesis genome specific DNA fragments. Apdsx900 shares little similarity with the silkwormBmdsxgene.……
