Mutation of the chloroplast-localized phosphate transporter OsPHT2;1 reduces flavonoid accumulation and UV tolerance in rice.

Phosphorus (P) is an essential macronutrient required for plant development and production. The mechanisms regulating phosphate (Pi) uptake are well established, but the function of chloroplast Pi homeostasis is poorly understood in Oryza sativa (rice). PHT2;1 is one of the transporters/translocators mediating Pi import into chloroplasts.

Phosphoproteomic Profiling Reveals the Importance of CK2, MAPKs and CDPKs in Response to Phosphate Starvation in Rice.

Phosphorus is one of the most important macronutrients required for plant growth and development. The importance of phosphorylation modification in regulating phosphate (Pi) homeostasis in plants is emerging. We performed phosphoproteomic profiling to characterize proteins whose degree of phosphorylation is altered in response to Pi starvation in rice root.

The role of OsNLA1 in regulating arsenate uptake and tolerance in rice.

Arsenic (As) contamination in agricultural soil can cause phytotoxicity and lead to As accumulation in crops. Rice (Oryza sativa) feeds half of the world's population, but the molecular mechanism of As detoxification is not well understood in rice. In this study, the role of OsNLA1 in arsenate uptake and tolerance in rice was analyzed.

A Phosphate-Starvation Induced RING-Type E3 Ligase Maintains Phosphate Homeostasis Partially Through OsSPX2 in Rice.

Phosphate (Pi), as the main form of phosphorus that can be absorbed by plants, is one of the most limiting macro-nutrients for plants. However, the mechanism for maintaining Pi homeostasis in rice (Oryza sativa) is still not well understood. We identified a Pi-starvation-induced E3 ligase (OsPIE1) in rice.
