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.
