PHR1 mediates rapid high light responses and acclimation to high photosynthetic activity.

The Plant journal : for cell and molecular biology - 1 May 2026

Abstract excerpt

Changing light intensity requires immediate metabolic adjustment which involves reprogramming of both plastidial and nuclear gene expression, but the signaling pathways behind such responses are not fully understood. Here we report that an increase in light intensity causes fluctuations of Pi levels in the chloroplasts of Arabidopsis thaliana and induces a transcriptional response mediated by the nuclear low-Pi...
