Abstract excerpt

Phosphate starvation response1 (PHR1) is a central transcription factor necessary for low phosphate (LP) response in plants, thus its activity is tightly regulated in plants. Here, we report that two members of the 14-3-3 protein family, GRF6 and GRF8, regulate PHR1 activity and LP response independently of SPX1 in Arabidopsis thaliana. GRF6 and GRF8 physically interact with PHR1, while disruption of both genes...
