Meiocyte-specific Small RNAs and Meiotic Recombination: Questions and Anthers
Research, The Plant Cell, The Plant Cell: In BriefSmall RNAs regulate gene expression and epigenetic modifications (via RNA-directed DNA methylation), and therefore play key roles in plant development (reviewed in Borges and Martienssen, 2015). Moreover, emerging evidence indicates that small RNAs may have a role in the repair of double-stranded breaks…
