概括

皮肤和牙抽样为鱼类提供了一种侵入性较小,非致命的DNA采样方法. 经过处理的皮肤拭片提供了与传统的片剪贴相匹配的DNA质量和全基因组测序性能.

科学领域:

水生生物学水生生物学
基因组学就是基因组学.
分子生态学分子生态学

背景情况:

剪是鱼类DNA采样的标准,但需要麻醉或安乐死.
需要非致命的采样方法来减少鱼群的压力和死亡率.

研究的目的:

评价皮肤和牙抹布作为DNA采样中片剪切的替代品.
为了比较DNA提取质量和整个基因组测序 (WGS) 的表现,在欧亚小鱼 (Phoxinus phoxinus) 的拭子和翅膀剪贴之间进行.

主要方法:

从片剪贴,皮肤抹布和牙抹布中提取了DNA.
通过光谱测量来评估DNA度和纯度.
通过对参考基因组进行测序和映射性能来确定WGS的适合性.

主要成果:

片总是达到DNA度值,而片需要特殊的保存和提取处理 (ATL缓冲器,蛋白酶K) 才能提高产量.
高比例的片片 (93.88%) 适合测序,而皮肤 (30.61%) 和牙 (7.69%) 则不适合测序.
尽管最初的适用性较低,但用蛋白酶K处理的皮肤抹布显示了与WGS中的片剪贴相似的映射性能.

结论:

当用蛋白酶K处理时,皮肤擦拭片是小鱼WGS翅切割的可行的非致命替代品.
这种方法减少了对麻醉或安乐死的需要,促进了道德和可持续的鱼类研究.
进一步优化基于扫描的DNA提取协议可以提高它们对WGS的适用性.

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...
