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.

Signals from major hormones and the environment are integrated in the Arabidopsis hypocotyl to control gene expression and plant stem elongation.

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.

G-quadruplex DNA regulates autophagy in neurons.

Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.

Controlling the duration of ligand binding to the T cell receptor by light shows that T cells discriminate stimulatory from non-stimulatory ligands by measuring the dynamics of ligand binding.
