Species Context Reverses PPIP5K Control of Fungal Morphogenesis and Actin Organization

The paper shows that the PPIP5K enzyme Asp1 produces opposite effects on fungal morphology and actin organization in different species, depending on the host cellular environment.

Lotus japonicus VIH2 is an inositol pyrophosphate synthase that regulates arbuscular mycorrhiza

The paper identifies VIH2 in Lotus japonicus as an inositol pyrophosphate synthase that regulates arbuscular mycorrhiza by linking phosphate starvation responses to root endosymbiosis.

NUDIX Hydrolases Target Specific Inositol Pyrophosphates and Regulate Phosphate Homeostasis and Bacterial Pathogen Susceptibility in Arabidopsis

A small signaling domain controls PPIP5K phosphatase activity in phosphate homeostasis.

This study identifies a GAF signaling domain that regulates PPIP5K phosphatase activity in phosphate homeostasis through structural and functional analyses.

Inositol pyrophosphate catabolism by three families of phosphatases controls plant growth and development

This study identifies three phosphatase families involved in inositol pyrophosphate catabolism in plants, showing their roles in growth, development, and nutrient signaling.
