    Genetic basis of sRNA quantitative variation analyzed using an experimental population derived from an elite rice hybrid

    Jia Wang, Wen Yao ... Qifa Zhang
    The expression of small RNAs (or sRNAs) is regulated not only by mRNA expression, but also by their own regulatory elements and by sRNA biogenesis genes.

    Circular synthesized CRISPR/Cas gRNAs for functional interrogations in the coding and noncoding genome

    Martin Wegner, Valentina Diehl ... Manuel Kaulich
    Cloning-free 3Cs technology is developed for the generation of sequence-bias-free covalently closed circular synthesized (3Cs) CRISPR/Cas gRNA libraries that can interrogate the coding and noncoding human genome.

    scRNA-sequencing reveals subtype-specific transcriptomic perturbations in DRG neurons of PirtEGFPf mice in neuropathic pain condition

    Chi Zhang, Ming-Wen Hu ... Yun Guan
    Single-cell RNA-sequencing unraveled cell subtype-specific transcriptomic changes in both injured and uninjured primary sensory neurons after nerve injury and demonstrated transcriptomic sexual dimorphism.

    A tudor domain protein, SIMR-1, promotes siRNA production at piRNA-targeted mRNAs in C. elegans

    Kevin I Manage, Alicia K Rogers ... Carolyn Marie Phillips
    SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.

    Functional genome-wide siRNA screen identifies KIAA0586 as mutated in Joubert syndrome

    Susanne Roosing, Matan Hofree ... Joseph G Gleeson
    A supervised learning approach on a high-content genome-wide siRNA screen has identified 591 likely candidates for ciliopathies and facilitated in the discovery of KIAA0586 mutations in individuals with Joubert syndrome.

    A DCL3 dicing code within Pol IV-RDR2 transcripts diversifies the siRNA pool guiding RNA-directed DNA methylation

    Andrew Loffer, Jasleen Singh ... Craig S Pikaard
    Double-stranded precursors of siRNAs involved in RNA-directed DNA methylation have initiating sequences and overhangs imparted by the RNA polymerases that synthesize them, programming alternative dicing reactions that diversify the siRNA pool.
