Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Area of Science:

Marine Microbiology
Biotechnology
Molecular Biology

Background:

Thraustochytrids are marine eukaryotes known for producing docosahexaenoic acid (DHA) and other valuable lipids.
DHA is an essential fatty acid for vertebrates, making thraustochytrids commercially important.
Genetic manipulation is crucial for optimizing thraustochytrid lipid production, but methods are strain-specific and not universally successful.

Purpose of the Study:

To systematically review existing genetic transformation methods for various thraustochytrid strains.
To compare transformation cassette designs used in thraustochytrids.
To provide guidance for establishing transformation protocols in new or challenging thraustochytrid species/strains.

Main Methods:

Systematic literature review of genetic transformation techniques applied to thraustochytrids.
Analysis and comparison of transformation cassette designs.
Discussion of potential challenges and solutions for genetic manipulation in non-model organisms.

Main Results:

Identified and compared diverse genetic transformation strategies employed across different thraustochytrid strains.
Highlighted variations in transformation cassette efficacy and design.
Discussed common obstacles encountered during the development of transformation protocols.

Conclusions:

Successful genetic transformation protocols are vital for unlocking the full biotechnological potential of thraustochytrids.
This review serves as a resource to guide future research in thraustochytrid genetic engineering.
The discussed approaches can inform protocol development for other recalcitrant non-model organisms.
