# A snapshot and pipeline for tissue-specific gene expression meta-analysis in honey bees

**William Cameron Jasper, Timothy A. Linksvayer, Joel Atallah, Daniel Friedman, Joanna C. Chiu, Brian R. Johnson** (2023) · Entomology

## Instructions

Use this skill when working with topics related to **honey bees, Apis mellifera, gene expression, RNA-Seq**.

When applying this skill:
1. Apply RNA-Seq to study the evolution of novel traits in social insects
1. Analyze coding sequence evolutionary rates in honey bees

## Key Concepts

- **honey bees**
- **Apis mellifera**
- **gene expression**
- **RNA-Seq**
- **novel traits**
- **taxonomically restricted genes**
- **coding sequence evolution**

## Methods & Techniques

- Conducted ten RNA-Seq experiments across various tissues in honey bees.
- Analyzed gene expression patterns to identify highly expressed taxonomically restricted genes (HE-TRGs).
- Examined differential gene expression between nurses and foragers to identify genes involved in social functions.
- Utilized statistical tests to assess the significance of TRG expression in novel versus conserved tissues.

## Key Findings

- Highly expressed TRGs play a significant role in tissues with novel functions compared to conserved tissues.
- Positively selected genes are often the least connected within gene expression networks.
- TRGs are critical for generating novel social functions and are frequently positively selected.
- The study suggests that genes with low network connectivity can evolve rapidly without incurring negative pleiotropic effects.

## Prerequisites

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