概括
双性基因在果新陈代谢中显著影响性别差异,大多数代谢物变异在它缺席时消失. 这强调了双人性.
科学领域:
- 代谢学 代谢学 代谢学
- 发育生物学 发展生物学
- 遗传学 是一个遗传学.
背景情况:
- 性别显著影响着生物体的新陈代谢,但解剖二态和性别特异性组织之间的相互作用仍然不清楚.
- 双性 (dsx) 基因是Drosophila melanogaster性发育的关键调节者,控制了解剖二重形态.
研究的目的:
- 调查双性 (dsx) 基因是性发育的关键调节者,它在多索菲拉黑菌的代谢中对性别差异 (SD) 的影响程度.
- 为了在多种组织中比较性二态野生类型的代谢物概况,与减少二态性 (dsx null flies) 的进行比较.
主要方法:
- 在野生类型XX和XYDrosophila melanogaster的三个不同的组织中量化91种不同的代谢物.
- 野生型和dsx无之间的代谢物丰度的比较,以评估dsx在代谢性差异中的作用.
主要成果:
- 很大一部分代谢物 (51%) 在野生的至少一个组织中表现出性别差异.
- 在 dsx null 中,性别差异基本上不存在,只有 kynurenate 显示变化,这表明 dsx 在代谢性SD 中发挥了主要作用.
- 与XY相比,XX的Kynurenate水平在野生类型和dsx无条件下始终更高.
- 在与器官生长相关的途径中丰富了二形代谢物,包括分支链氨基酸和mTOR途径.
结论:
- 双性基因在Drosophila melanogaster的代谢中建立性别差异方面发挥着关键作用.
- 的两性变异与各种组织中代谢的实质性改变有关,部分是由器官生长途径介导的.

The Ratio of X Chromosome to Autosomes
8.8K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Dosage Compensation

In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...
