Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

30.4K
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.

Horizontal Gene Transfer01:27

Horizontal Gene Transfer

1.1K
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:...

Gene Flow02:39

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Transduction01:16

Transduction

986
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome...

Overview of Transposition and Recombination02:13

Overview of Transposition and Recombination

18.6K
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...

Summary

Horizontal gene transfer, the movement of DNA between species, is increasingly found in insects. Some acquired genes provide new functions, like enhanced digestion and pathogen resistance, impacting insect evolution.

Area of Science:

  • Genomics
  • Evolutionary Biology
  • Molecular Biology

Background:

  • Horizontal gene transfer (HGT) involves genetic material transfer across species.
  • While rare in animals, HGT is increasingly detected in insect genomes due to genomic data expansion.
  • Most HGT sequences are non-functional, but some confer adaptive traits.

Purpose of the Study:

  • To investigate the functional significance of horizontally acquired genes in insects.
  • To identify novel functions conferred by exogenous DNA in insect recipients.
  • To understand the evolutionary implications of HGT in insect adaptation.

Main Methods:

  • Analysis of large-scale genomic datasets to identify exogenous DNA inserts in insect genomes.
  • Gene expression analysis to confirm the functionality of horizontally acquired genes.
