果蝇

Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.

对分别采自辽东湾、莱州湾、海州湾和舟山的三疣梭子蟹4个野生群体的线粒体16S rRNA和COⅠ基因片段进行了扩增和测序，分别得到长度为524bp和658bp的片段。2段序列的碱基组成均显示较高的A+T比例（16S rRNA基因70.8%，COⅠ基因63%），这与果蝇、虾类、蟹类等无脊椎动物的16S rRNA和COⅠ基因片段研究结果相似。

We report a previously uncharacterized alpha-helical module, the BEN domain, in diverse animal proteins such as BANP/SMAR1, NAC1 and the Drosophila mod(mdg4) isoform C, in the chordopoxvirus virosomal protein E5R and in several proteins of polydnaviruses.

In this thesis, we find that dlg is indispensible in the establishment of anterior-posterior and dorsal-ventral polarity of drosophila oocyte. Removal of Dlg function from the posterior follicle cells using the FLP/FRT system leads to disruption of oocyte skeleton reconstruction that is elicited by the failure of those posterior cells to differentiate normally in mid-oogenesis. We demonstrate that abnormity of Notch, JAK-STAT and EGFR signal pathway in dlg mutants contributes to this aberrant differentiation. dlg null mutant also blocks the normal differentiation of two groups of anterior follicle cell-stretched cell and centripetal cell, but not border cell, with a lower penetrance. However unlike the result in posterior follicle cells, Notch and JAK-STAT signaling are both undisrupted in all mutant anterior follicle cells, implying other fate determinants may be involved.

我们的研究发现，后端滤泡细胞中的Dlg在果蝇卵子发生中期卵母细胞前后轴和背腹轴建立过程中也是必须的，PFC中dlg完全缺失型突变引起PFC的分化异常，导致卵子发生中期卵母细胞骨架重组异常，Stau、Grk等极性决定蛋白定位错误。dlg突变阻碍了Notch、JAK-STAT、EGFR等调节PFC分化的信号通路的激活。dlg突变的PFC也没有获得前端滤泡细胞命运。dlg突变不影响前端滤泡细胞群中边界细胞的分化，但是在一定程度上影响伸展细胞和向心细胞的分化，并且这种影响不依赖于前端滤泡细胞Notch或JAK-STAT信号激活的异常。
