The Doublesex gene of S. litura (Sldsx) has male-specific Sldsx M and female-specific Sldsx F isoforms, and exhibits a higher expression level in the male testis. At the testicular fusion stage (L6D6), Sldsx attained the highest expression compared to the pre-fusion and post-fusion ...
The gene doublesex (dsx) is known as a key factor regulating genetic sex determination in many organisms. We previously identified two dsx genes (DapmaDsx1 and DapmaDsx2) from a freshwater branchiopod crustacean, Daphnia magna, which are expressed in males but not in females. D. magna prod...
另外,BxRBP1和BxRBP2的也不受到Masc的调控。 8. 作者构建了包含dsx基因所有外显子以及截短内含子的可变剪接微型基因(mini-gene),检测Masc和BxRBPs是否能够直接调控dsx基因的可变剪切。在雌性家蚕细胞系中,dsx微型基因以雌性特异模式剪切。过量表达Masc能够有效抑制第3和第4外显子的剪切,产生雄性特异基因产物。过量表...
For some time now, the gene 'fruitless' (fru), which is specific to the adult male fruit fly, was thought to be the key to male behaviour and the development of male specific neural circuitry of flies. However, the researchers have shown that fru does not explain the complete repertoire ...
7. A gene drive designed to disrupt theA. gambiaefertility geneAGAP007280initially increased in frequency, but the selection of nuclease-resistant, functional variants that could be detected as early as generation 2 completely blocked the spread of the drive2. Resistant variants comprised small ...
Which of the following ideas is accepted by scientists? A The "doublesex" gene does do everything by itself C The "doublesex" gene "tells" other genes to change the wing patterns B The "doublesex" gene is poisonous D The "doublesex" gene could only control the color of the upper par...
The doublesex (dsx) gene functions as a molecular switch at the base of the insect sex determination cascade and triggers male or female somatic sexual differentiation in Drosophila. Having been reported from only seven current insect orders, the exact p

In the model system Drosophila melanogaster, doublesex (dsx) is the double-switch gene at the bottom of the somatic sex determination cascade that determines the differentiation of sexually dimorphic traits. Homologues of dsx are functionally conserved in various dipteran species, including the malaria...
