Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

7.1K
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...

Single Nucleotide Polymorphisms-SNPs

18.8K
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,...

Comparing Copy Number Variations and SNPs

18.9K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Synteny and Evolution02:31

Synteny and Evolution

3.9K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Epistasis Analysis01:09

Epistasis Analysis

6.0K
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

Genetic Variation01:25

Genetic Variation

1.5K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Area of Science:

  • Plant genetics
  • Genomics
  • Agricultural science

Background:

  • Eggplants comprise three Old World domesticates: brinjal (Solanum melongena), scarlet (S. aethiopicum), and gboma (S. macrocarpon).
  • Understanding genetic diversity and relationships among these species and their wild relatives is crucial for crop improvement and evolutionary studies.

Purpose of the Study:

  • To characterize the genomic DNA of cultivated eggplants and wild relatives.
  • To identify single nucleotide polymorphisms (SNPs) and analyze genetic relationships within the eggplant germplasm.
  • To provide insights into the evolutionary history and genetic improvement potential of eggplants.

Main Methods:

  • Genotyping-by-sequencing (GBS) approach was employed to analyze genomic DNA.
  • A total of 210 million useful reads were generated and aligned to the reference eggplant genome.
  • Polymorphic sites were identified, and genetic relationships were analyzed using FastSTRUCTURE and principal coordinates analysis.

Main Results:

  • 75,399 polymorphic sites were identified, with 12,859 in coding sequences.
  • Four major sub-groups were identified, clustering related domesticates and wild ancestors.
  • Clear species separation was observed, though not always between domesticates and their wild progenitors; no clear differentiation was found based on cultivar groups or geographical origin.

Conclusions:

  • The genotyping-by-sequencing approach is highly efficient for quantifying genetic diversity and establishing genetic relationships in eggplants.
  • The study provides valuable information for understanding eggplant evolution and for future genetic improvement strategies.
  • Genetic relationships among cultivated and wild relatives offer a foundation for targeted breeding programs.
