Overview of Transposition and Recombination02:13

Overview of Transposition and Recombination

17.7K
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...

Horizontal Gene Transfer01:27

Horizontal Gene Transfer

634
Horizontal gene transfer (HGT) is a process where genetic material moves between organisms within the same generation, unlike vertical gene transfer, which occurs from parent to offspring. HGT plays a crucial role in microbial evolution, adaptation, and survival, particularly in shared environments like the human gut.Mobile genetic elements such as plasmids, prophages, integrons, insertion sequences, and transposons facilitate this process. HGT occurs through three primary mechanisms:...

DNA-only Transposons

15.2K
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

Transposons01:24

Transposons

476
Transposons, or "jumping genes," are small mobile genetic elements (MGEs) that range from 700 to 40,000 base pairs in length. They are found in all organisms and can move within the same chromosome or transfer to different chromosomes. In some cases, transposons can also jump between different host DNA molecules, such as plasmids or viruses, contributing to genetic variability.Barbara McClintock first discovered these mobile genetic elements in the 1940s while studying maize genetics, and she...

Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

29.9K
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.

Area of Science:

  • Plant genomics
  • Molecular evolution
  • Bioinformatics

Background:

  • Limited genome resources hinder the study of horizontal DNA transfer (HT) in plants.
  • Investigating HT is crucial for understanding plant genome evolution and diversification.

Purpose of the Study:

  • To assess the utility of low-depth sequencing data for plant HT investigations.
  • To identify instances of HT in panicoid grasses and their interactions with other plant species.

Main Methods:

  • Comparative genomics analysis of low-depth sequencing data from 19 panicoid grass samples against 115 angiosperm genomes.
  • Focused investigation on HT between Echinochloa (panicoid) and Oryza (rice) species using non-targeted analysis.

Main Results:

  • Frequent horizontal transfer of LTR-retrotransposons identified between panicoids and rice (Oryza sativa).
  • Recurrent HTs of diverse transposable element (TE) types were found between Echinochloa and Oryza species.
  • One specific case of HT from Echinochloa to Oryza with overlapping geographic distribution was confirmed.

Conclusions:

  • Low-depth sequencing data is effective for investigating HT in plants with limited genomic resources.
  • Horizontal transfer plays a significant role in the diversification of plant transposable element repertoires.
  • While challenging, HT analysis using genomic data provides insights into plant genome evolution.
