Sensory perception of fluctuating light in Arabidopsis

The paper shows that Arabidopsis thaliana detects low-frequency sunflecks through phytochrome B, cryptochromes, and UVR8, leading to growth adjustments and gene expression changes.

Water shortage reduces PHYTOCHROME INTERACTING FACTOR 4, 5 and 3 expression and shade avoidance in Arabidopsis

This study shows water shortage reduces PIF4, PIF5, and PIF3 expression and shade avoidance in Arabidopsis by affecting their promoter activity and nuclear abundance.

Hysteresis in PIF4 and ELF3 dynamics dominates warm daytime memory in Arabidopsis

The paper shows that Arabidopsis hypocotyl growth during the night depends on both current and previous daytime temperatures, mediated by PIF4 and ELF3 dynamics.

In Arabidopsis, low blue light enhances phototropism by releasing cryptochrome 1-mediated inhibition of PIF4 expression

COP1 destabilizes DELLA proteins in Arabidopsis

This paper shows that COP1 destabilizes DELLA proteins in Arabidopsis through ubiquitination, independent of gibberellin signaling, and this process is relevant for growth responses to shade and warm temperature.

Neighbor signals perceived by phytochrome B increase thermotolerance in Arabidopsis

This study shows that Arabidopsis plants grown under shade conditions exhibit increased thermotolerance, mediated by reduced phytochrome B activity and changes in fatty acid composition.
