Functional genetics for all: engineered nucleases, CRISPR and the gene editing revolution

Area of Science:

• Developmental biology
• Evolutionary developmental biology (evo-devo)
• Genetics

Background:

• Experimental science, including developmental biology, relies heavily on technological advancements.
• Genetic tools in model organisms have been crucial for understanding development, physiology, and behavior.
• Extending these tools to diverse species is key for studying developmental diversity and evolution.

Purpose of the Study:

• To examine the application, limitations, and opportunities of these tools in gene targeting for evo-devo research.
• To highlight how CRISPR/Cas technology can bridge the gap between established and emerging model organisms.

Main Methods:

• Review of gene editing technologies including zinc-finger nucleases, TALENs, and CRISPR/Cas systems.
• Analysis of applications in gene targeting, including gene knock-out and knock-in approaches.
• Discussion of methods for manipulating gene functions by directing molecular effectors to specific genomic sites.

Main Results:

• Gene knockdown and deep sequencing technologies have enabled wider species applicability in evo-devo.
• CRISPR/Cas offers precise genome alteration capabilities, revolutionizing developmental genetics.
• CRISPR's ease-of-use and efficiency in diverse species facilitate research beyond traditional model organisms.

Conclusions:
