These Bio-NPs, approximately 21 nm in diameter and characterized by a negative surface charge, were used as priming agents for maize seeds.

However, the differential impacts of short-term low-temperature stress on the photosynthetic activity of these tissues and their protective mechanisms remain underexplored. In this study, the cotton cultivar \"Xinluzao 45\" was subjected to three temperature regimes in a controlled climate chamber: Control (30°C/20°C), T1 (16°C/10°C), and T2 (12°C/8°C). After two days of treatment, pigment content, photosynthetic activity, light energy distribution, and cyclic electron flow (CEF) around photosystem I were analyzed in both leaf and non-leaf green tissues. Results showed that short-term low-temperature stress decreased the maximum photochemical efficiency of PSII (Fv/Fm), actual photochemical efficiency [Y(II)], and maximum photo-oxidizable P700 (Pm) in both leaf and non-leaf green tissues. Compared to leaves and bracts, cotton boll shells exhibited greater photosynthetic stability, which was related to their higher carotenoid (Car) content, larger plastoquinone (PQ) pool, and enhanced CEF capacity under stress. Chemical inhibitor experiments (using antimycin A and rotenone) indicated that PGRL1/PGR5-mediated CEF plays a more critical role than the NDH pathway in cotton's response to short-term low-temperature stress.

This review investigates how the integration of nanotechnology with genetically modified (GM) crops can offer solutions to agricultural challenges by improving crop resilience and productivity. While genetic modification has faced limitations in achieving consistent results due to environmental variability and species-specific differences, nanotechnology has emerged as a transformative tool to enhance GM crop performance. In this study we critically explore the underlying mechanisms of combining nanotechnology with GM crops to enhance plant growth and development and their resilience against biotic and abiotic stresses. Furthermore, nanotechnology also play a crucial role in targeted gene delivery, precise genome editing, and controlled regulation of gene expression in GM plant cells. Overall, the emerging role of nanotechnology in GM crops is paving the way for innovative solutions in agriculture. By leveraging nanotechnology, researchers are exploring novel approaches to enhance productivity, combat plant diseases, and improve plant resilience to environmental stress for sustainable agriculture.

This newly identified acclimation process enables the cooling of reproductive organs under conditions of WD + HS, limiting HS-induced damage to plant reproduction. However, the thresholds at which DT remains active and effectively cools reproductive tissues, as well as the developmental stages at which it is activated in soybean, remain unknown. Here, we report that DT occurs at most nodes (leaf developmental stages) of soybean plants subjected to WD + HS, and that it can function under extreme conditions of WD + HS (i.e., 18% of field water capacity and 42°C combined). Our findings reveal that DT is an effective acclimation strategy that protects reproductive processes from extreme conditions of WD + HS at almost all developmental stages.

Recent findings suggest that root ABA levels are predominantly leaf-sourced and not locally synthesized, thus, ABA exported from the roots in the xylem is mostly recycled from the shoot. To explain the differential root hormone accumulation observed under partial rootzone drying (PRD) that imposes distinct dry and wet parts of the root zone, we grafted \"two-root, one-shoot\" soybean plants to independently assess xylem export of different phytohormones from either part of the root zone. Grafts were subjected to a combination of girdling (either part, all, or none of the rootzone) and irrigation (homogenously well-watered (WW) and PRD). PRD did not increase foliar ABA but decreased stomatal conductance, attributed to decreased leaf water potential and/or increased xylem sap ABA, JA, or ACC concentrations. In contrast, the foliar ABA increments that accompanied girdling-induced stomatal closure were proportional to the root fraction to which phloem transport was interrupted. Irrespective of girdling, root ABA accumulation (and xylem ABA export from) was highest in the dry PRD rootzone, xylem jasmonic acid (JA) in the wet PRD rootzone, and xylem ACC in both rootzones of PRD plants. Thus, soil drying of the dry root zone and transient overwatering of the wet root zone enhanced ACC export in PRD plants. We conclude that root water status during PRD enhances root ABA, JA and ACC synthesis and xylem export, independent of shoot-to-root transport.</p>","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"177 3","pages":"e70252"},"PeriodicalIF":5.4,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12041630/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144049930","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}

WRKY transcription factors revealed great potential in elevating crop resistance to environmental factors. This study assessed the roles of Arabidopsis WRKY30 (AtWRKY30) in regulating wheat tolerance to Cr toxicity, salt stress, bacterial leaf blight and stripe rust. Wild-type and AtWRKY30-overexpressing wheat plants were exposed to non-stressful conditions, Cr toxicity (0.5 mM K₂Cr₂O₇), salt stress (150 mM NaCl), and pathogen infections (Pss or Pst). The results indicated that Cr and salt stresses restricted the growth and reduced the level of chlorophyll, gas exchange rates and potassium content in wheat plants. However, under Cr and salt toxicity, AtWRKY30 overexpression in wheat significantly reduced the levels of oxidative stress biomarkers and minerals (Cr, sodium, and chloride), augmented the growth and yield components, and enhanced the levels of chlorophyll, potassium, gas exchange, osmoprotectants, enzymatic antioxidants, redox components, and expression of stress-related genes compared to wild-type plants. AtWRKY30 overexpression also significantly reduced bacterial leaf blight and stripe rust symptoms in wheat plants infected with Pss and Pst, respectively.

In the mature stand, root and stem hydraulic conductivity reached maximum values of 3.18 × 10^-2 kg m s^-1 MPa^-1 and 3.54 × 10^-2 kg m s^-1 MPa^-1, respectively. There was a clear tradeoff between hydraulic safety and efficiency in the root xylem, while this tradeoff was relatively weak in the stem xylem.

In the roots, however, the age-dependent embolism resistance was strongest in middle-aged stands, with a P₅₀ value of -1.86 MPa.
