報(bào)告題目Hztransib in Helicoverpa zea: history, intragenomic dynamics and regulation

報(bào) 李顯春 教授  美國亞利桑那大學(xué)

報(bào)告時(shí)間201163日上午10:00-11:30

報(bào)告地點(diǎn):北校區(qū)6B三層會(huì)議室

報(bào)告摘要:  Hztransib, characterized in the cotton bollworm (Helicoverpa zea), is the first intact member of Transib, a novel superfamily of transposable elements (TEs) originally reconstructed in silico from ancient fossil TE sequences in the genomes of Drosophila melanogaster and Anopheles gambiae. In this talk, He will demonstrate that Hztransib had probably transferred to H. zea from H. armigera and still retains its capacity to maintain structural integrity, increase copy number and remobilize in H. zea. He will then demonstrate the unique regulatory mechanism of Hztransib that permits its long-term persistence in the host genome.

  歡迎廣大師生參加!
