In protected cropping systems (PCS), which are controlled environments for intensive agriculture, optimizing K management is essential for attaining sustainable productivity and resilience under stressful growth conditions. Understanding plant responses to these conditions requires advanced analytical approaches, and metabolomics is emerging as a key tool, though there is still a lack of PCS-focused metabolomic studies. This review synthesizes the recent knowledge on plant metabolomic responses to K as a nutrient, emphasizing the central role of metabolomics in uncovering intricate biochemical pathways associated with K uptake, transport, and utilization. We investigate essential metabolic alterations in response to K deficiency, encompassing modifications in glucose metabolism, antioxidant synthesis, osmolyte accumulation, and hormonal regulation. The review also explores the relationships between potassium and other nutrients, specifically nitrogen, phosphorus, and essential micronutrients, and their impact on total plant metabolic networks. Furthermore, we discuss cutting-edge omics integration, precision fertigation, real-time sensor technologies, and machine learning applications that together promise to transform K fertilizer management in PCS. Future directions highlight the advancement of K-efficient cultivars, integrating metabolomic biomarkers in breeding, and overcoming challenges in data interpretation, scalability, and the high cost of metabolomic analyses and phenotyping technologies. Collectively, these insights provide a framework for improving crop health, production, and nutrient utilization efficiency for a more sustainable future in protected cropping.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"177 5","pages":"e70547"},"PeriodicalIF":3.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12460989/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145138188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Receptor-like kinases (RLKs), located on the cell surface, play a pivotal role in recognizing extracellular signal molecules and activating downstream signaling pathways. Receptor-like cytoplasmic kinases (RLCKs), lacking extracellular ligand-binding domains, function as downstream partners of RLKs to transduce the signals to intracellular signaling components such as the mitogen-activated protein kinase (MAPK) cascade. RLCKs are classified into 17 subfamilies, which are further divided into distinct branches based on sequence similarity. Among the RLCKs, the XII-1 members, known as BRASSINOSTEROID-SIGNALING KINASEs (BSKs), play key roles in regulating diverse physiological processes. Given their importance, this review highlights recent advances in understanding the role of BSKs in plant growth, development, and stress responses. We detail the regulation of BSKs' subcellular localization through post-translational modifications and explore the molecular mechanisms by which BSKs modulate signaling pathways by engaging with RLK receptors and MAPK cascades. We also discuss the other signaling pathways regulated by BSKs. Collectively, this review underscores the role of BSKs as potential linker proteins localized at the plasma membrane (PM), functioning downstream of cell surface receptors and upstream of MAPK cascades and other signaling components to orchestrate a multitude of developmental processes and stress responses.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"177 5","pages":"e70555"},"PeriodicalIF":3.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145192438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant response to these stresses consists of overlapping pathways that, coupled with the emerging use of endophytic fungi as biological control agents (BCAs) and plant biostimulants, enables the study of their potential to mitigate co-occurring biotic stresses and nutritional deficiencies such as Fe deficiency. To this end, Arabidopsis thaliana plants of the \"Columbia\" ecotype grown in calcareous soil were inoculated with the non-pathogenic strain Fusarium oxysporum FO12 and/or with the defoliating pathotype of V. dahliae strain V180. Plant growth, plant mineral uptake, and disease progression, along with the molecular quantification of FO12 and V180 fungal biomass and the relative expression of ISR-, SAR-, and Fe deficiency-related genes in shoots, were evaluated. The results revealed that plants inoculated with the FO12 strain increased growth, leaf chlorophyll concentration (SPAD index), and phosphorus (P; 126%) and Fe (9%) contents, partially due to ethylene (ET) and Iron Man peptides (IMA). In addition, FO12 reduced the severity of symptoms by more than 85%. This reduction in disease severity may be attributed to a direct competitive effect on V180 progression and to the induction of several defence-associated genes related to ET and SA synthesis and signaling. This bidirectional crosstalk between Fe deficiency responses and plant defences triggered by FO12 mainly through ET can improve plant resilience while reducing reliance on agrochemicals, offering a sustainable multifaceted tool for crop protection and nutrition management.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"177 5","pages":"e70550"},"PeriodicalIF":3.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12485298/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145200687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the differences in morphology and adaptability between the GG and YG ecotypes are not elucidated. In this study, we investigated and compared GG and YG ecotypes' cuticular wax and its composition. Furthermore, the difference in drought tolerance between the leaves of the two ecotypes was analyzed. Our results showed that GG plants have stronger drought tolerance owing to an optimal limiting non-stomatal water loss effect than the YG plants, which is associated with their higher proportion of tubular epicuticular wax. The composition of the tubular wax was mainly β-diketone 14,16-Hentriacontanedione (C31H60O2), and its biosynthesis may be closely related to the endoplasmic reticulum-localized diketone metabolism type-III polyketide synthase (DMP).

However, the limited phloem mobility of certain nutrients and nonsystemic pesticides reduces the effectiveness of these strategies. Nanoparticles (NPs) have emerged as promising carriers to improve nutrient use efficiency (NUE) and crop protection by enabling long-distance transport and targeted delivery of essential nutrients and active ingredients. While increasing evidence suggests that foliar-applied NPs can translocate within plants, a mechanistic understanding and agronomically relevant case studies remain scarce. As a result, the extent to which NP translocation can facilitate significant distribution and cargo release within plants is yet to be fully established. This review critically evaluates existing research on foliar NP translocation, emphasizing key findings within a plant science framework. Specifically, we examine how NP design can influence translocation and assess the existing quantitative data of NP remobilization within plants. Additionally, we explore how physiological processes affect NP transport and highlight alternative, often overlooked translocation pathways. Lastly, we assess current techniques used to study NP transport, discussing their applicability and limitations. This review identifies significant research gaps that must be addressed to advance nano-enabled plant nutrition as well as crop protection and can therefore be used to inspire future research.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"177 5","pages":"e70476"},"PeriodicalIF":3.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12381517/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144965109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
