# The Dynamic Effects of Transposon Insertions on AuxRP1 Transcription During Vegetative Development in Zea mays

## TL;DR

This study explores how transposon insertions affect the transcription of the AuxRP1 gene during the growth stages of corn plants.

## Contribution

The study reveals stage-specific effects of transposon insertions on AuxRP1 transcription and related gene pathways in corn.

## Key findings

- Transposon insertions caused decreased or unchanged AuxRP1 transcription at the juvenile stage but increased it at the transition/adult stage.
- Transposon insertions affect related genes like TSB2C and Yucca2, influencing biosynthetic pathways.
- The effects of transposon insertions are stage-specific and impact auxin signaling and stalk rot resistance.

## Abstract

The
AuxRP1
gene (
Zm00001eb053610
) is involved in the auxin signaling pathway and stalk rot resistance in
Zea mays
. In this study, we examined four transposon insertion lines (UFMu-03429, UFMu-00414, UFMu-08200, and AcDs-00676) targeting
AuxRP1
. Transcription of
AuxRP1
of the insertion lines either decreased or remained unchanged at the juvenile (V3) stage but increased significantly at the transition/adult (V6) stage. We also analyzed its upstream gene
TSB2C
and downstream gene
Yucca2
. Our results show that transposon insertions can induce stage-specific changes in gene expression that affect related biosynthetic pathways.
