Summary
Invasive species adapt to new environments through phenotypic plasticity, often without genetic changes. Transcriptomics reveals how regulatory mechanisms facilitate this adaptation, crucial for understanding invasion biology.
Area of Science:
- Ecology
- Evolutionary Biology
- Genomics
Background:
- Invasive species must overcome environmental mismatches to establish in novel ecosystems.
- Research increasingly focuses on trait variation, adaptation, and genomic factors driving invasion success.
- Omics tools, especially transcriptomics, are vital for understanding species establishment and plasticity.
Purpose of the Study:
- To review transcriptomic studies in invasion biology.
- To evaluate the role of regulatory mechanisms in invasive species plasticity.
- To identify future research directions and limitations in using transcriptomics for invasion studies.
Main Methods:
- Comprehensive literature review of transcriptomics in invasion biology.
- Collating evidence on regulatory processes contributing to invasive species plasticity.
- Identifying knowledge gaps and methodological challenges.
Main Results:
- Transcriptomics offers insights into trait-specific plasticity supporting invasion.
- Evidence is mixed regarding the extent to which regulatory processes drive plasticity in invasive species.
- Plasticity allows phenotypic variation without immediate genomic alteration.
Conclusions:
- Transcriptomics is a powerful tool for studying invasive species adaptation.
- Understanding regulatory mechanisms is key to predicting and managing biological invasions.
- Further research is needed to refine transcriptomic approaches and address methodological limitations.

01:23Regulation of Expression at Multiple Steps
873
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

02:24Regulation of Expression Occurs at Multiple Steps
22.5K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

01:17Transcription
20.4K
Transcription is the synthesis of RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in correctly synthesizing messenger RNA (mRNA). Transcriptional regulation is responsible for the differentiation of different types of cells and often for the proper cellular response to environmental signals.

01:36What is Gene Expression?
8.4K
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then...

02:23Master Transcription Regulators
6.9K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...
