Analyzing single molecules reveals that Pif1 family helicases periodically patrol DNA, which may explain this enzyme's ability to suppress genome instability at G-quadruplex motifs and transcriptional RNA-DNA hybrids (R-loops).

A phosphorylation dependent translocation of PIF7 and involvement of 14-3-3 proteins reveal novel regulation mechanisms in shade signal transduction.

The abundance of the PIF4 transcription factor, central in light and temperature signaling, is controlled by an E3 ligase encoded by BOP proteins.

A sharp transition in the fate of DNA ends with telomere sequences is identified, which suggests a boundary between DNA double-strand breaks and telomeres.

A combination of genetics and biophysical approaches identifies an overlapping set of sequences that form non-canonical G-quadruplex structures in vitro and induce genomic instability in cells.

HEC transcription factors control the timing of cell fate transitions in a dynamic stem cell system, allowing plants to adapt their developmental program to diverse environments.

Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.

Ded1p and eIF4A, two RNA helicases that function in eukaryotic translation initiation, interact physically with each other and with the scaffolding protein eIF4G.
