The Plant Cell, Год журнала: 2024, Номер 36(5), С. 1504 - 1523

Опубликована: Янв. 2, 2024

As an essential nutrient element, phosphorus (P) is primarily acquired and translocated as inorganic phosphate (Pi) by plant roots. Pi often sequestered in the soil becomes limited for growth. Plants have developed a sophisticated array of adaptive responses, termed P starvation to cope with deficiency improving its external acquisition internal utilization. Over past 2 3 decades, remarkable progress has been made toward understanding how plants sense respond changing environmental P. This review provides overview molecular mechanisms that regulate or coordinate emphasizing transport, sensing, signaling. We present major players regulators responsible uptake translocation. then introduce perceived at root tip, systemic signaling operated, which intracellular status sensed conveyed. Additionally, recent exciting findings about influence on plant-microbe interactions are highlighted. Finally, challenges prospects concerning interplay between other nutrients strategies enhance utilization efficiency discussed. Insights obtained from this knowledge may guide future research endeavors sustainable agriculture.

ABSTRACT Phosphorus (P) is vital for plant growth, and continuous P fertiliser application necessary to increase yield quality, but it can cause environmental pollution. Plants maintain a steady phosphate (Pi) supply through complex signalling pathways. Phosphate starvation response 1 (PHR1), key regulator of Pi signals in plants, enables plants sufficient level. However, the role PHR1 fruit quality remains unclear. In this study, we determined function Fragaria vesca (FvPHR1) by overexpressing FvPHR1 gene. We identified validated two downstream genes investigating phenotypes analysing RNA‐Seq data. directly enhanced expression transporter 1;7 ( FvPHT1;7 ), increasing uptake improving photosynthesis efficiency. Additionally, upregulated sugar will eventually be exported 9 FvSWEET9 which encodes that facilitates transport from leaves fruit. enhance photosynthetic products source via pathway facilitate sink FvSWEET9. plays complicated providing molecular foundation developing strawberry cultivars with highly efficient utilisation processes high content.

Phosphorus (P) deficiency limits the growth, development and productivity of rice. To better understand underlying mechanisms in P-deficiency tolerance role Pup1 QTL enhancing P use efficiency (PUE) for P-efficient rice cultivars, a pair contrasting genotypes (Pusa-44 NIL-23) was used to investigate morpho-physio-biochemical proteomic changes under P-starvation stress. The were grown hydroponically PusaRich medium with adequate (16 mg/kg, +P) or without (0 -P) 30 d. manifested significant reductions root shoot biomass, length, leaf area, total chlorophyll, phosphorus, nitrogen starch contents as well protein kinase activity. stress increased root-to-shoot biomass ratio, sucrose content acid phosphatase activity, particularly tolerant genotype (NIL-23). Comparative proteome analysis revealed several metabolism-associated proteins (including OsCDPKs, OsMAPKs, OsCPKs, OsLecRK2 OsSAPks) be expressed NIL-23, indicating that multiple kinases involved P-starvation/deficiency tolerance. Moreover, up-regulated expression OsrbcL, OsABCG32, OsSUS5, OsPolI-like B ClpC2 shoot, OsACA9, OsACA8, OsSPS2F, OsPP2C15 OsBiP3 NIL-23 indicated their control through QTL.

Legume plants can acquire mineral nitrogen (N) either through their roots or via a symbiotic interaction with N-fixing rhizobia bacteria housed in root nodules. To identify shoot-to-root systemic signals acting Medicago truncatula at N deficit satiety, were grown split-root experimental design which high low was provided to half of the system, allowing analysis pathways independently any local response. Among plant hormone families analyzed, cytokinin trans-zeatin accumulated satiety. Cytokinin application by petiole feeding led inhibition both growth and nodulation. In addition, an exhaustive miRNAs revealed that miR2111 accumulates systemically under shoots non-treated distant roots, whereas miRNA related inorganic phosphate (Pi) acquisition, miR399, These two accumulation patterns are dependent on Compact Root Architecture 2 (CRA2), receptor required for C-terminally Encoded Peptide (CEP) signaling. Constitutive ectopic expression miR399 reduced nodule numbers biomass depending Pi availability, suggesting miR399-dependent Pi-acquisition regulatory module controlled availability affects development whole legume system.
