**Daniel A. Friedman, Deborah M. Gordon, Liqun Luo** (2017) · Entomology

## Instructions

Use this skill when working with topics related to **CRISPR/Cas9, Orco gene, olfactory receptor, ant genetics**.

When applying this skill:
1. Evaluate CRISPR/Cas9 gene editing applications in non-model organisms
1. Understand olfactory receptor evolution and social insect pheromone communication
1. Analyze the functional genetics of collective behavior in eusocial insects

## Key Concepts

- **CRISPR/Cas9**
- **Orco gene**
- **olfactory receptor**
- **ant genetics**
- **Ooceraea biroi**
- **Harpegnathos saltator**
- **social behavior**
- **pheromone**
- **gene knockout**

## Methods & Techniques

- Injected freshly-laid ant eggs with purified Cas9 protein and synthetic guide RNAs targeting the Orco gene.
- Conducted behavioral assays to assess the impact of Orco knockout on ant behavior and reproductive performance.
- Utilized olfactory assays to evaluate sensitivity to semiochemicals in Orco null mutants.
- Analyzed neuroanatomical structures in mutant ants to identify defects in the antennal lobe.

## Key Findings

- Homozygous Orco mutants displayed altered behavior, decreased reproductive capacity, and increased mortality.
- Orco null mutants showed reduced sensitivity to olfactory stimuli and unique behaviors such as increased wandering.
- Both studies found significant neuroanatomical defects in the antennal lobe of Orco mutants, indicating a developmental role for the gene.
- The research underscores the importance of olfaction in ant social behavior and adaptation to diverse environments.

## Prerequisites

- Evolutionary biology and ecology fundamentals
- Social insect biology and colony organization
