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.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
