Journal ArticleDOI
Methylation as a Crucial Step in Plant microRNA Biogenesis
Bin Yu,Zhiyong Yang,Junjie Li,Svetlana Minakhina,Maocheng Yang,Richard W. Padgett,Ruth Steward,Xuemei Chen +7 more
TL;DR: It is shown that plant microRNAs (miRNAs) have a naturally occurring methyl group on the ribose of the last nucleotide, a new and crucial step in plant miRNA biogenesis and have profound implications in the function of miRNAs.
Journal ArticleDOI
Methylation protects miRNAs and siRNAs from a 3′-end uridylation activity in Arabidopsis
TL;DR: It is concluded that 3'-end methylation is a common step in miRNA and siRNA metabolism and likely protects the 3' ends of the small RNAs from the uridylation activity.
Journal ArticleDOI
HEN1 recognizes 21–24 nt small RNA duplexes and deposits a methyl group onto the 2′ OH of the 3′ terminal nucleotide
TL;DR: It is shown that HEN1 methylates both miRNA/miRNA* and siRNA/siRNA* duplexes in vitro with a preference for 21–24 nt RNA duplexe with 2 nt overhangs and the importance of the 2′-O-methyl group in the biology of RNA silencing is implicate.
Journal ArticleDOI
Transgenically expressed viral RNA silencing suppressors interfere with microRNA methylation in Arabidopsis.
TL;DR: In this article, several viral RNA silencing suppressors (P1/HC-Pro, p21 and p19) have been found to inhibit miRNA methylation in vivo.
Journal ArticleDOI
Floral patterning defects induced by Arabidopsis APETALA2 and microRNA172 expression in Nicotiana benthamiana.
TL;DR: The studies uncover the potential utility of the ArabidopsisAP2/miR172 system as a tool for manipulation of floral architecture and flowering time in non-model plants.
