RNA silencing (RNAi) induced by virus-derived double-stranded RNA (dsRNA), which is in a sense regarded as a pathogen-associated molecular pattern (PAMP) of viruses, is a general plant defense mechanism. To counteract this defense, plant viruses express RNA silencing suppressors (RSSs), many of which bind to dsRNA and attenuate RNAi. We showed that the(More)
The arylhydrocarbon receptor (AhR) is the receptor for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and related compounds. Although a physiological ligand for the AhR has yet to be identified, and the precise physiological roles of the AhR are unknown, it may play important roles not only in the regulation of xenobiotic metabolism but also in the maintenance(More)
Many plant viruses encode suppressors of RNA silencing, including the helper component-proteinase (HC-Pro) of potyviruses. Our previous studies showed that a D-to-Y mutation at amino acid position 193 in HC-Pro (HC-Pro-D193Y) drastically attenuated the virulence of clover yellow vein virus (ClYVV) in legume plants. Furthermore, RNA-silencing suppression(More)
Numerous physiological processes are regulated by endocrine systems in animals. Endocrine-disrupting chemicals (EDCs) can affect physiological processes of organisms by binding to hormone receptors. Therefore, it is necessary to develop methods for detecting EDCs and removing them from the environment. We have developed a simple and low-cost reporter gene(More)
Epigenetic modifications, such as posttranslational modifications of histones, play an important role in gene expression and regulation. These modifications are in part mediated by the Trithorax group (TrxG) complex and the Polycomb group (PcG) complex, which activate and repress transcription, respectively. We herein investigate the role of Menin, a(More)
