  Evaluation Summary:

  In this study, the authors examined the function of the RNA-binding protein FPA through analyzing its protein interactome and its global impact on gene expression using a combined approach of Nanopore DRS, Helicos DRS, and short-read Illumina RNA-Seq. The combined datasets and new computational approaches developed by the authors permitted them to identify the predominant role of FPA in promoting poly(A) site choice. The authors further revealed that FPA mediates widespread premature cleavage and polyadenylation of transcripts of NLR genes, important plant immune regulators. Overall, this study suggests that control of transcription termination processes mediated by FPA provides an additional layer of the regulatory dynamics of NLRs in plant immune responses.

  Summary: In this paper you describe experiments showing that PIE-1 is sumoylated at K68, and that K68 sumoylation plays a role in PIE-1 interaction with HDA-1 and its sumoylation, which leads to its activation. The reviewers found the sumoylation dependence of PIE-1 function in piRNA silencing to be of interest, but raised major issues that need to be addressed. In particular, more mechanistic insights into how sumoylation of PIE-1 at K68 enhances HDA-1 sumoylation and regulation are required.

  Summary: In this paper, your studies showed that sumoylation of HDA-1, a type 1 HDAC, at two C-terminal Lys residues plays a role in establishing transcriptional silencing of piRNA-regulated genes in C. elegans through enhanced NuRD complex interaction and histone H3 deacetylation. The reviewers all found the link between HDA-1 sumoylation and silencing to be interesting, but raised a number of issues that need to be addressed.
