# Genetic Mapping and Phenotypic Analysis of GstE14 E.4.1 on Eye and Antennae Development in Drosophila melanogaster

## TL;DR

This paper identifies a new mutation in the GstE14 gene that affects eye and antennae development in fruit flies.

## Contribution

The study discovers a novel GstE14 mutant allele linked to developmental defects in Drosophila.

## Key findings

- The E.4.1 mutant causes rough eyes and antennae overgrowth in Drosophila.
- GstE14 is involved in ecdysone biosynthesis and tissue growth regulation.
- Loss of GstE14 leads to developmental timing disruptions.

## Abstract

Genetic screens are valuable for identifying novel genes involved in the regulation of developmental processes. To identify genes associated with cell growth regulation in
Drosophila melanogaster
, a mutagenesis screen was performed. Undergraduate students participating in Fly-CURE phenotypically characterized the
E.4.1
mutant which is associated with rough eyes and antennae overgrowth. Following complementation analysis and subsequent genomic sequencing,
E.4.1
was identified as a novel mutant allele of

GstE14

, a gene involved in ecdysone biosynthesis important for the timing of developmental events. The abnormal eye and antenna phenotypes observed resulting from the loss of

GstE14

suggest its role in tissue growth.
