Overview of Transposition and Recombination02:13

Overview of Transposition and Recombination

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...
Genome Annotation and Assembly03:36

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
DNA-only Transposons02:57

DNA-only Transposons

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...
Transgenic Plants02:50

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
Cis-regulatory Sequences02:02

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
Plant Breeding and Biotechnology01:59

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Summary
This summary is machine-generated.

Standardized annotation of plant transposable elements (TEs) is crucial. Consistent methods are needed to understand how TEs influence epigenome changes, gene expression, and inheritance, especially under stress.

Area of Science:

  • Genomics
  • Epigenetics
  • Plant Science

Background:

  • Whole genome sequences are available for many plants.
  • Transposable elements (TEs) are a major genome component and influence epigenome changes under stress.
  • TE annotation has received less attention than gene annotation.

Purpose of the Study:

  • To highlight the importance of fine-scale characterization and annotation of plant transposable elements (TEs).
  • To argue for standardized annotation methods for TEs.
  • To underscore the role of TEs in epigenome regulation, gene expression, and non-Mendelian inheritance.

Main Methods:

  • This is an opinion article, not based on experimental data.
  • Literature review and synthesis of current knowledge on TE annotation and epigenetics.

Main Results:

  • Lack of focus on repeat fraction characterization and inconsistent TE annotation methods hinder understanding of TE influence.
  • Epigenetic regulation by TEs can occur rapidly (single generation), unlike major structural genome changes.
  • Standardized TE annotation is essential for critical insights.

Conclusions:

  • Standardized annotation of TEs is vital for understanding their impact on plant epigenomes, gene expression, and inheritance.
  • Addressing the lack of focus and consistent methods in TE annotation is critical for advancing plant genomics and epigenetics research.
