Linker histone H1 and cytosine DNA methylation in contexts other than CG explain patterns of 24 nucleotide small RNA biogenesis in Arabidopsis thaliana.

Various types of stress reset heritable small RNA responses through the function of the p38 MAPK pathway, the transcription factor SKN-1/Nrf2, and the MET-2/SETDB1 putative histone methyltransferase.

The identification of a SUMO E3 ligase engaged in lncRNA transcription, subsequently leading to target-directed small RNA degradation, reveals an unexplored layer of regulatory mechanisms within small RNA-directed chromatin regulation.

In Caenorhabditis elegans histone methylation (H3K9me3) controls the synthesis of heritable small RNAs in a gene-specific manner and thus enables 'flagging' of newly-acquired genes.

Genome-wide profiling and functional analyses reveal a network of heterochromatin and small RNA factors that silences repetitive elements and prevents genotoxic stress to ensure fertility.

Small RNAs of distantly related plant pathogens, such as fungi and oomycetes, hijack the plant RNA-induced silencing complex to favor host infection.

The genome sequence of Trichoplusia ni enables the use of this widespread lepidopteran pest as a model for both the study of small RNA pathways and insecticide resistance.

Primate-specific miR-934 mediates neurogenesis and downstream neuronal differentiation processes, modulating the expression of genes associated with the subplate, a region most prominent in primates, emerging during early cortical development.

Transcribed promoters are highly susceptible to mutation by cytidine deaminases, implicating stable exposure of single stranded DNA structures, rather than cofactors, in localising mutation during tumourigenesis and antibody maturation.

Superfamilies of trans-species small RNAs from the parasitic plant Cuscuta have sequence variation that correspond to synonymous site variation in host plant target mRNAs.
