Coordinated responses and adaptations to these stressors are critical for plant growth, development, and survival. However, the underlying molecular response and adaptation mechanisms in plants are not fully understood. Here, we show that plants use a reciprocal antagonistic strategy in response to UV radiation and P deficiency. UV radiation inhibits P-starvation response processes and disrupts phosphate (Pi) homeostasis by suppressing the function of PHOSPHATE STARVATION RESPONSE PROTEINS (PHRs), the Pi central regulators. Conversely, P availability modulates plant UV tolerance and the expression of UV radiation response genes in a PHR-dependent manner. Therefore, reducing the P supply or increasing PHR activities can improve tolerance to UV stress in rice. Moreover, this antagonistic interaction is conserved across various plant species. Our meta-analysis showed that the increase in global UV radiation over the last 40 years may have reduced crop P-utilization efficiency worldwide. Our findings provide insights for optimizing P fertilizer management and breeding smart crops that are resilient to fluctuations in UV radiation and soil P levels.</p>","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101140"},"PeriodicalIF":9.4,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11783903/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142376225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proteomic analysis demonstrated that SAP18 is a core component of the nuclear apoptosis- and splicing-associated protein (ASAP) complex in Arabidopsis, contributing to the precise splicing of genes associated with leaf development. Genetic analysis further confirmed the critical role of SAP18 in different developmental processes as part of the ASAP complex, including leaf morphogenesis and flowering time. Interestingly, upon heat shock, SAP18 translocates from the nucleus to cytoplasmic stress granules and processing bodies. The heat-sensitive phenotype of a SAP18 loss-of-function mutant revealed a novel role for SAP18 in plant thermoprotection.

Investigating the mechanisms of interspecies allelopathic interactions for disease suppression in agroforestry offers a sustainable strategy for plant disease management. Here, we used Panax ginseng cultivated under Pinus koraiensis forests, which have low occurrences of Alternaria leaf spot, as a model to explore the role of allelochemicals in disease suppression. Our findings demonstrate that foliar application of P. koraiensis needle leachates effectively enhanced the resistance of P. ginseng against Alternaria leaf spot. Using gas chromatography-mass spectrometry, we identified and quantified endo-borneol as a key compound in P. koraiensis leachates and confirmed its ability to prime resistance in neighboring P. ginseng plants. We discovered that endo-borneol not only directly activates defense-related pathways in P. ginseng to confer resistance but also indirectly recruits its beneficial rhizospheric microbiota by promoting the secretion of ginsenosides, thereby triggering induced systemic resistance. Notably, higher concentrations of endo-borneol, ranging from 10 to 100 mg/l, have a greater capacity to induce plant resistance and enhance root secretion, thereby recruiting more microbiota compared to lower concentrations ranging from 0.01 to 1 mg/l. Additionally, endo-borneol exhibits antifungal activities against the growth of the pathogen Alternaria panax when concentrations exceeded 10 mg/l. These results reveal the multifaceted functions of allelochemical endo-borneol in disease suppression within agroforestry systems and highlight its potential as an environmentally friendly agent for sustainable agriculture.</p>","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101173"},"PeriodicalIF":9.4,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11783886/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142480445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we demonstrate that pepper rotation markedly reduces Meloidogyne incognita infection in cucumber and diminishes the presence of p-hydroxybenzoic acid in the soil, a compound known to exacerbate M. incognita infection. Pepper rotation also restructures the rhizobacterial community, leading to the colonization of the cucumber rhizosphere by two Pseudarthrobacter oxydans strains (RH60 and RH97), facilitated by enrichment of palmitic acid in pepper root exudates. Both strains exhibit high nematocidal activity against M. incognita and have the ability to biosynthesize indoleacetic acid and biodegrade p-hydroxybenzoic acid. RH60 and RH97 also induce systemic resistance in cucumber plants and promote their growth. These data suggest that the pepper root exudate palmitic acid alleviates M. incognita infection by recruiting beneficial P. oxydans to the cucumber rhizosphere.

Their homeostasis is mostly maintained by C-terminal serine phosphorylation. However, the kinases that phosphorylate PIPs and manipulate their turnover are largely unknown. Here, we found that Arabidopsis thaliana PIP2;7 positively regulates plant immunity by transporting H₂O₂. Arabidopsis CALCIUM-DEPENDENT PROTEIN KINASE 28 (CPK28) directly interacts with and phosphorylates PIP2;7 at Ser273/276 to induce its degradation. During pathogen infection, CPK28 dissociates from PIP2;7 and destabilizes, leading to PIP2;7 accumulation. As a countermeasure, oomycete pathogens produce conserved kinase effectors that stably bind to and mediate the phosphorylation of PIP2;7 to induce its degradation. Our study identifies PIP2;7 as a novel substrate of CPK28 and shows that its protein stability is negatively regulated by CPK28. Such phosphorylation could be mimicked by Phytophthora kinase effectors to promote infection. Accordingly, we developed a strategy to combat oomycete infection using a phosphorylation-resistant PIP2;7^S273/276A mutant.

Compared with available SNP-based genotyping platforms, a genotyping by target sequencing (GBTS) system with capture-in-solution (liquid chip) technology has become the favored genotyping technology because it is less demanding and more cost effective, flexible, and user-friendly. In this study, a new GenoBaits WheatSNP16K (GBW16K) GBTS array was designed using datasets generated by the wheat 660K SNP array and resequencing platforms in our previous studies. The GBW16K array contains 14 868 target SNP regions that are evenly distributed across the wheat genome, and 37 669 SNPs in these regions can be identified in a diversity panel consisting of 239 wheat accessions from around the world. Principal component and neighbor-joining analyses using the called SNPs are consistent with the pedigree information and geographic distributions or ecological environments of the accessions. For the GBW16K marker panel, the average genetic diversity among the 239 accessions is 0.270, which is sufficient for linkage map construction and preliminary mapping of targeted genes or quantitative trait loci (QTLs). A genetic linkage map, constructed using the GBW16K array-based genotyping of a recombinant inbred line population derived from a cross of the CIMMYT wheat line Yaco\"S\" and the Chinese landrace Mingxian169, enables the identification of Yr27, Yr30, and QYr.nwafu-2BL.4 for adult-plant resistance to stripe rust from Yaco\"S\" and of Yr18 from Mingxian169.
