  • Endogenous and antiviral RNA silencing pathways in Arabidopsis

    Creator:
    Chapman, Elisabeth J.
    Abstract:
    RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

  • Small RNA pathways in plants

    Creator:
    Montgomery, Taiowa A.
    Abstract:
    miRNA-guided cleavage initiates entry of primary transcripts into the trans-acting siRNA (tasiRNA) biogenesis pathway involving RNA-DEPENDENT RNA POLYMERASE6 (RDR6), DICER-LIKE 4 (DCL4), and SUPPRESSOR OF GENE SILENCING3 (SGS3). Arabidopsis thaliana TAS1 and TAS2 families yield tasiRNA that form through miR173- guided initiation cleavage on the 5’ side of the siRNA-generating...
