Coordinated phosphate uptake by extracellular alkaline phosphatase and solute carrier transporters in marine diatoms

Hiroaki Matsui, Hisashi Harada, Kanako Maeda, Toshiki Sugiyama, more

Marine diatoms express genes encoding potential phosphate transporter and alkaline phosphatase (APase) under phosphate‐limited (−P) condition. This indicates that diatoms use high‐affinity phosphate uptake system with organic phosphate hydration. The function of molecules playing roles for Pi uptake was determined in this study. Pi uptake and APase activity of two marine diatoms, Phaeodactylum tricornutum...

Soluble organic nutrients induce ClaPhys expression to enhance phytase activity of watermelon roots

Shujun Li, Bingshuang Wang, Yuan Wang, Xuewei Ma, more

Annals of Applied Biology > 181 > 1 > 80 - 92

Application of organic fertilisers is beneficial to the quality and yield of crops. Myo‐inositol phosphate is an abundant form of organic phosphorus (P_o) in organic manure and soil, which could release phosphate (P_i) and likely be absorbed by plant after it was hydrolysed by phytase. However, whether plant roots respond to organic fertiliser to adapt myo‐inositol phosphates utilisation is not clear...

OsWRKY21 and OsWRKY108 function redundantly to promote phosphate accumulation through maintaining the constitutive expression of OsPHT1;1 under phosphate‐replete conditions

Jun Zhang, Mian Gu, Ruisuhua Liang, Xinyu Shi, more

New Phytologist > 229 > 3 > 1598 - 1614

Plant Phosphate Transporter 1 (PHT1) proteins, probably the only influx transporters for phosphate (Pi) uptake, are partially degraded on sufficient Pi levels to prevent excessive Pi accumulation. Therefore, the basal/constitutive expression level of PHT1 genes is vital for maintaining Pi uptake under Pi‐replete conditions. Rice (Oryza sativa) OsPHT1;1 is a unique gene as it is highly expressed...

The Hebeloma cylindrosporum HcPT2 Pi transporter plays a key role in ectomycorrhizal symbiosis

Adeline Becquer, Kevin Garcia, Laurie Amenc, Camille Rivard, more

New Phytologist > 220 > 4 > 1185 - 1199

Through a mutualistic relationship with woody plant roots, ectomycorrhizal fungi provide growth‐limiting nutrients, including inorganic phosphate (Pi), to their host. Reciprocal trades occur at the Hartig net, which is the symbiotic interface of ectomycorrhizas where the two partners are symplasmically isolated. Fungal Pi must be exported to the symbiotic interface, but the proteins facilitating...

Phosphate Limitation Alters Medicago–Sinorhizobium Signaling: Flavonoid Synthesis and AHL Production

N. Pakdaman, A. Mostajeran

Russian Journal of Plant Physiology > 2018 > 65 > 2 > 251-259

The legume plant Medicago truncatula Gaertn. can establish a symbiotic interaction with Sinorhizobium meliloti. One of the most limiting factors for symbiosis is phosphate (P) deficiency. Therefore, legumes and their symbiotic partners, rhizobia, have developed mechanisms to adapt to P restriction. In the non-symbiotic state, plants would up-regulate flavonoid biosynthesis via increasing the expression...
