Overexpression of the MYB-related transcription factor GCC7 in Arabidopsis thaliana leads to increased levels of Pi and changed P-dependent gene regulation
TL;DR: It is concluded that GCC7 is not strictly required for a P-starvation response since the gcc7 mutant responds to Pi limitation, and this family, with 15 members in Arabidopsis thaliana (L.) Heynh.

TL;DR: This work demonstrates the successful BSMV-mediated virus induced gene silencing (VIGS) of three different genes in barley roots, i.e. the barley homologues of the IPS1, PHR1, and PHO2 genes known to participate in Pi uptake and reallocation in Arabidopsis.
The Arabidopsis transcription factor PHR1 is essential for adaptation to high light and retaining functional photosynthesis during phosphate starvation.
TL;DR: It is concluded that PHR 1 is needed for the metabolic balance, for retaining P(i) levels and for inducing anthocyanin production, and during P deficiency PHR1 is vital for adaptations to avoid permanent damage to photosystems during high-light conditions.
Dissecting the plant transcriptome and the regulatory responses to phosphate deprivation
TL;DR: Evaluating the contribution of the regulatory elements to the P-responses and presenting a model comprising factors directly or indirectly involved in transcriptional regulation and the role of miRNAs as regulators and long-distance signals suggest that these mechanisms are instrumental in providing an accurate response and in keeping P-homeostasis.
