概括
与Cnidarian相关的Chlamydiae表现出巨大的多样性和强制性的细胞内生活方式,缺乏独立生存的基因. 这项研究揭示了它们的功能潜力和广泛的宿主范围,影响了对珊瑚微生物群的理解.
科学领域:
- 微生物学 微生物学
- 海洋生物学 海洋生物学
- 基因组学就是基因组学.
背景情况:
- 类动物含有各种细菌,对宿主健康和营养循环至关重要.
- 约束性细胞内细菌的作用,特别是Clamydiota (chlamydiae),在cnidarian宿主,特别是珊瑚,仍然在很大程度上是未知的.
- 了解这些细菌的关联对于理解珊瑚全生物体的功能至关重要.
研究的目的:
- 为了研究类动物相关的类动物的多样性和功能潜力.
- 为了确定珊瑚和水母中chlamydiae的生活方式和宿主特异性.

Channel Rhodopsins
2.6K
Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

Lampbrush Chromosomes

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
