In animals, a discrete class of small RNAs, the piwi-interacting RNAs (piRNAs), guard germ cell genomes against the activity of mobile genetic elements. piRNAs are generated, via an unknown mechanism, from apparently single-stranded precursors that arise from discrete genomic loci, termed piRNA clus...
ORGANISM(S): Mus musculus 
Combining RNAi in cultured cells and analysis of mutant animals, we probed roles of known piRNA pathway components in the initiation and effector phases of transposon silencing. total RNA and RNA associated with Piwi was isolated and size-fractionated by PAGE into 19-29nt. These were processed and s...
ORGANISM(S): Drosophila melanogaster 
RNA sequencing performed on the root tips of rtel1 mutants and Col-0
ORGANISM(S): Arabidopsis thaliana 
RNA sequencing performed on the root tips of wee1-1 and wee1-1/rnh2a mutants, treated for 24h with or without 2mM hydroxyurea.
ORGANISM(S): Arabidopsis thaliana 
Drosophila Argonaute-1 and Argonaute-2 differ in function and small RNA content. AGO2 binds to siRNAs, whereas AGO1 is almost exclusively occupied by microRNAs. microRNA duplexes are intrinsically asymmetric, with one strand, the miR strand, preferentially entering AGO1 to recognize and regulate the...
