Alteration of gene expression networks with a rice transposon mPing

The rice transposon mPing is expected as a genetic tool to create genes showingnovel expression profiles since the mPing insertions render adjacent genes stress inducible. In this study, we first established the screening system for mutant genes harboring de novo mPing insertion into the upstream region. Then, we evaluated the effect of the mPing insertion on the expression profiles of stress-response genes. Furthermore, we investigated the methylation degree of promoter region of stress-response genes harboring the mPing insertion. It was found that mPing could confer various expression profiles to stress-response genes independent of DNA methylation.
