WebFeb 6, 2024 · In plants, small RNAs are produced to coordinate plant development, maintain genome integrity, and combat adverse environmental conditions (Buchon and Vaury, 2006; Chen, 2009; Ruiz-Ferrer and Voinnet, 2009 ). The mobility of small RNAs was presumed to be a prerequisite for carrying out these functions. WebApr 22, 2010 · In the plant RNA interference (RNAi) pathway, 21-nucleotide duplexes of small interfering RNA (siRNA) are processed from longer double-stranded RNA precursors by the RNaseIII Dicer-like 4 (DCL4). Single-stranded siRNAs then guide Argonaute 1 (AGO1) to execute posttranscriptional silencing of complementary target RNAs.
