TL;DR: The identification of genome-wide PIF5-binding sites during shade avoidance revealed that this bHLH transcription factor regulates the expression of a subset of previously identified SAS genes, and this study suggests that PIF4 and Pif5 regulate elongation growth by controlling directly the expression for auxin biosynthesis and auxin signaling components.

TL;DR: It is shown that PKS1 induction by a pulse of blue light is phytochrome A-dependent, suggesting that the PKS proteins may provide a molecular link between these two photoreceptor families.

TL;DR: It is shown that ultraviolet-B light perceived by the photoreceptor UV RESISTANCE LOCUS 8 (UVR8) strongly attenuates thermomorphogenesis via multiple mechanisms inhibiting PIF4 activity, demonstrating complex crosstalk between UV-B and high-temperature signaling.

TL;DR: It is shown that cotyledon-derived auxin is both necessary and sufficient to initiate hypocotyl growth, but also provided evidence for the functional importance of the local PIF-induced response, and a growth promotion gene expression signature is uncovered.

TL;DR: It is shown that phototropic hypocotyl bending is strongly dependent on the activity of D6PKs and the PIN proteins PIN3, PIN4, and PIN7, and the findings suggest that D6 PK-mediated phosphorylation of PIN transporters promotes auxin transport in the hypocrotyl to ensure proper phototropic hypocrisy bending.
