Exon Recombination02:32

Exon Recombination

3.5K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon...

Gene Conversion02:08

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

7.8K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Gene Duplication and Divergence02:37

Gene Duplication and Divergence

5.9K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

26.7K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Overview of Transposition and Recombination02:13

Overview of Transposition and Recombination

15.0K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Area of Science:

  • Evolutionary biology
  • Genetics
  • Molecular biology

Background:

  • Genetic variation is a key driver of animal trait diversity.
  • The mechanisms underlying the evolutionary reuse of specific genes remain incompletely understood.

Purpose of the Study:

  • To investigate the factors that make certain genes prone to evolutionary reuse.
  • To explore how the evolution of a single transcription factor contributes to adaptive variation.

Main Methods:

  • Analysis of genetic variation across different animal lineages.
  • Investigating the role of a specific transcription factor in trait evolution.

Main Results:

  • A small number of genes account for significant animal trait diversity.
  • The evolution of a single transcription factor underlies adaptive variation.
  • This underlies variation across both micro- and macro-evolutionary scales.

Conclusions:

  • Specific genes are predisposed to evolutionary reuse.
  • Transcription factor evolution is a significant mechanism for generating adaptive traits.
  • This mechanism operates across diverse evolutionary timescales.
