Abstract Nitrogen (N), potassium (K), and phosphorus (P) are essential macronutrients for
plant growth and development, and their availability affects crop yield. Compared with N, the …

In eukaryotic cells, gene expression is greatly influenced by the dynamic chromatin
environment. Epigenetic mechanisms, including covalent modifications to DNA and histone …

Plants are sessile organisms that need to adapt to constantly changing environmental
conditions. Unpredictable climate change places plants under a variety of abiotic stresses …

The maintenance of cellular phosphate (Pi) homeostasis is of great importance in living
organisms. The SPX domain-containing protein 1 (SPX1) proteins from both Arabidopsis …

It has been almost 25 years since the first report of the gene encoding a high-affinity
phosphate transporter (PT), PHO84, in yeast. Since then, an increasing number of yeast …

Plant vacuoles serve as the primary intracellular compartments for inorganic phosphate (Pi)
storage. Passage of Pi across vacuolar membranes plays a critical role in buffering the …

Highlights•Pi stress restricts primary root growth through dual regulatory pathways.•Vacuolar
transporters regulate cytosolic Pi homeostasis.•InsP interacts with SPX domain to regulate Pi …

Highlights•Inositol polyphosphates act as signals in phosphate homeostasis.•ROS signaling
is associated to phosphate and iron control of root tip growth.•Thousands of RNAs in the …

In plants, phosphate (P i) homeostasis is regulated by the interaction of PHR transcription
factors with stand-alone SPX proteins, which act as sensors for inositol pyrophosphates. In …

The multidomain target of rapamycin (TOR) is an atypical serine/threonine protein kinase
resembling phosphatidylinositol lipid kinases, but retains high sequence identity and serves …
