- 分子生物学分子生物学
背景情况:
- 过度开发药用植物,如Curcuma fenestrata,威胁到自然资源,改变了性别比例.
- 有效的保护需要性别特定的恢复,但在生殖成熟期 (15年C. fenestrata) 之前,性别差异化是困难的.
- 目前缺乏早期性别识别方法,阻碍了对C. fenestrata的资源增强计划.
研究的目的:
- 利用转录学来开发一种方法,在幼苗阶段区分C. fenestrata个体的性别.
- 在C. fenestrata中确定早期性别识别的遗传标记,以支持保护和资源管理.

Single Nucleotide Polymorphisms-SNPs
15.1K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Genome-wide Association Studies-GWAS
13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
