The Rice Dwarf Virus P2 Protein Interacts with ent -Kaurene Oxidases in Vivo, Leading to Reduced Biosynthesis of Gibberellins and Rice Dwarf Symptoms
TL;DR: Evidence is provided that the P2 protein of RDV interferes with the function of a cellular factor, through direct physical interactions, that is important for the biosynthesis of a growth hormone leading to symptom expression, and may provide a novel tool to investigate the regulation of GA metabolism for plant growth and development.
Journal ArticleDOI
Viral-inducible Argonaute18 confers broad-spectrum virus resistance in rice by sequestering a host microRNA
Jianguo Wu,Zhirui Yang,Yu Wang,Lijia Zheng,Ruiqiang Ye,Yinghua Ji,Shanshan Zhao,Shaoyi Ji,Ruofei Liu,Le Xu,Hong Zheng,Yijun Zhou,Xin Zhang,Xiaofeng Cao,Lianhui Xie,Z.J. Wu,Yijun Qi,Yi Li +17 more
TL;DR: It is reported that rice resistance to evolutionarily diverse viruses requires Argonaute18 (AGO18), and a novel cooperative antiviral activity of two distinct AGO proteins is uncovered, suggesting a new strategy for the control of viral diseases in rice.
Journal ArticleDOI
ROS accumulation and antiviral defence control by microRNA528 in rice.
Jianguo Wu,Rongxin Yang,Zhirui Yang,Shengze Yao,Shanshan Zhao,Yu Wang,Pingchuan Li,Xianwei Song,Lian Jin,Tong Zhou,Ying Lan,Lianhui Xie,Xueping Zhou,Chengcai Chu,Yijun Qi,Xiaofeng Cao,Yi Li +16 more
TL;DR: The findings reveal a mechanism in which antiviral defence is boosted through suppression of an miRNA that negatively regulates viral resistance, which could be manipulated to engineer virus-resistant crop plants.
Journal ArticleDOI
Virus infection triggers widespread silencing of host genes by a distinct class of endogenous siRNAs in Arabidopsis
Mengji Cao,Peng Du,Xian-Bing Wang,Yun-Qi Yu,Yan-Hong Qiu,Wan-Xiang Li,Amit Gal-On,Changyong Zhou,Yi Li,Shou-Wei Ding +9 more
TL;DR: It is proposed that antiviral RNAi activates broad-spectrum antiviral activity via widespread silencing of host genes directed by vasiRNAs in addition to specific antiviral defense by viral siRNAs.
Journal ArticleDOI
Viral infection induces expression of novel phased microRNAs from conserved cellular microRNA precursors.
TL;DR: These results provide a comparative analysis of changes in the small RNA profiles and in the genes of RNA silencing machinery induced by different viruses in a natural and economically important crop host plant, and uncover new mechanisms and complexity of virus-host interactions.
