Summary: The study found that NaCl can promote the reutilization of root cell wall P in P-starved rice through increasing the activity of pectin methylesterase and the uronic acid content in pectin. Additionally, NaCl can facilitate the translocation of P from root to shoot in P-starved rice, and ABA is involved in the regulation of NaCl-mediated root cell wall P reutilization.

Summary: The study found that biochar can improve the phosphorus solubilization capacity of phosphorus-solubilizing bacteria (PSB) by affecting the organic acid and polysaccharide contents, and phosphatase activity secreted by the PSB. This can help improve the utilization of soil phosphorus and reduce phosphorus fertilizer pollution.

Summary: Intracellular phosphate homeostasis is crucial for cell metabolism and growth. Under short-term phosphate starvation, plants induce the expression of acid phosphatase OsACP1 to recycle phosphate from organic phosphate, impacting plant growth and productivity under both sufficient and deficient phosphate conditions. OsACP1 plays a key role in regulating rice growth by recycling phosphate from organic sources in the endoplasmic reticulum and Golgi apparatus.

Summary: The study demonstrates that increasing pectin methylesterase (PME) activity can facilitate the redistribution of phosphorus (P) deposited in the cell wall, alleviating P deficiency in rice. Lower methylesterification degree of pectin contributes to releasing more inorganic phosphorus, and the expression of the OsPME14 gene is related to PME activity.

Summary: In this study, the responses of soil P fractions to litter removal in different forest types were investigated, and the acquisition pathway of bioavailable P in forest conversion was examined. The results showed that soil P content increased with the conversion from primary to secondary forest, mainly due to differences in nutrients and species richness. Primary forest had active organic P as the main source of bioavailable P, while secondary forest relied on mineral P. Litter removal significantly decreased primary forest soil P fraction content and increased secondary forest bioavailable P content.

Summary: This study investigates the impact of molybdenum and phosphorus treatments on root morphology, nutrient uptake, and gene expression and metabolism in soybean plants. The results show that molybdenum application can enhance biomass, lateral root growth, and phosphorus concentration and accumulation. It also regulates the synthesis and secretion of organic acids and acid phosphatase, thereby increasing the availability of phosphorus in the soil. The findings suggest that molybdenum plays a crucial role in plant adaptation to different phosphorus levels.

Summary: The study reveals that strigolactones play a crucial role in shaping the phosphorus acquisition strategies in tomato plants, with their depletion leading to inefficient activation of various mechanisms associated with the phosphorus starvation response. This results in reduced phosphorus uptake and increased carbon and nitrogen costs under both phosphorus-depleted and normal phosphorus conditions.

Summary: Seed phosphorus content plays a significant role in seedling vigor and crop growth. However, there are contradictory observations on the influence of seed phosphorus content on seedling vigor. This study used rice mutants to investigate the role of seed phosphorus content on seedling vigor and associated physiological processes. The results suggest that seed phosphorus content affects seedling vigor, chlorophyll content, photosynthesis, and phosphorus transport in young seedlings.

Summary: Using rice straw and phosphorus solubilizing microbes (PSMs) treatments can improve the availability of phosphorus in tropical agricultural soils. Soil temperature and moisture have significant effects on phosphorus solubilization and mineralization processes. Changes in soil silicon concentration and pH are the main factors influencing soil phosphorus mobilization.

Summary: This study investigates the role of secreted proteins in maintaining cell structure and regulating stress responses in plant cells. The researchers found that OsPHR2 plays a crucial role in the regulation of different types of secreted proteins in response to phosphate deprivation. The OsPHR2-dependent systemic Pi signaling pathway mainly regulates phosphatases and PR proteins, while the OsPHR2-independent local Pi signaling pathway mainly regulates ROS metabolism proteins, cell wall-remodeling proteins, and signal transduction proteins.

Summary: Plants have evolved a local Pi signaling pathway to solubilize occluded Fe-P or Al-P oxides by inducing malate secretion. Pi limitation impairs brassinosteroid signaling and downregulates BZR1 expression in Arabidopsis. Exogenous treatment with 2,4-epibrassinolide or constitutive activation of BZR1 significantly reduces primary root growth inhibition under Pi-starvation conditions by downregulating ALMT1 expression and malate secretion.

Summary: This study investigated the role of LPR1 in Cd stress and found that the overexpression of LPR1 resulted in reduced primary root lengths, fresh weights, lengths of the non-root hair zone, and chlorophyll contents. It also triggered ROS bursts and reduced the entry of available iron into the cell, which induced the expression of IRT1 and exacerbated the Cd influx into plants. These findings highlight the pathway of LPR1-mediated plant response to Cd toxicity stress through the regulation of ROS and Fe homeostasis.

Summary: In this study, a NAC transcription factor, OsSNAC1, was found to have a positive regulatory role in nitrate uptake and utilization in rice. It directly binds to the upstream promoter regions of OsNRT2.1/2.2 and OsNRT1.1A/1.1B and activates their expression, increasing nitrate concentrations, N uptake, NUE, and NUI in rice plants, as well as plant biomass and yield. These findings provide a potential genetic approach for improving crop NUE in agriculture.
