PIF4 and PIF5 transcription factors link blue light and auxin to regulate the phototropic response in Arabidopsis.

The Plant cell - 1 Jun 2013

Abstract excerpt

Both blue light (BL) and auxin are essential for phototropism in Arabidopsis thaliana. However, the mechanisms by which light is molecularly linked to auxin during phototropism remain elusive. Here, we report that phytochrome interacting factoR4 (PIF4) and PIF5 act downstream of the BL sensor pho...
