WebApr 12, 2024 · In plants, RNA silencing is an important conserved mechanism to regulate gene expression and combat against abiotic and biotic stresses. Dicer-like (DCL) and Argonaute (AGO) proteins and RNA-dependent RNA polymerase (RDR) are the core elements involved in gene silencing and their gene families have been explored in many plants. … WebApr 12, 2024 · The world of small noncoding RNAs (sncRNAs) is ever-expanding, from small interfering RNA, microRNA and Piwi-interacting RNA to the recently emerging non-canonical sncRNAs derived from...
WebRNA silencing involves the processing of dsRNA by the enzyme Dicer into small RNAs, 21 to 25 nucleotides in length (1–3).One of the two RNA strands is then incorporated into a protein complex called RNA-induced silencing complex (RISC) that invariably contains a member of the highly conserved ARGONAUTE protein family (4, 5).The incorporated small …
