Nevertheless, there is a huge gap in the research of this area, and investigations are being conducted to determine the potential detrimental impacts of the nanomaterials and the means of eliminating the potential toxicities. In our research, we investigated the potential of zinc oxide nanoparticle (ZnONPs) tolerant <em>Trichoderma pseudoharzianum</em> T113 strains in reducing the toxicity of ZnO NPs in tomato crops. Our research findings of a very thoroughly investigated experiment on mechanism of action revealed that application of T113 in NPs amended soil triggered an appreciable change in the microbial diversity of the soil and improved the population density and diversity of the growth-promoting soil microbes and fungi that produced glomalin, a protein responsible for metal chelating. The amount of glomalin in the soil was significantly improved in soil by T113 strain inoculation. The diversity and abundance of the microbes, having beneficial impacts on plants and the glomalin in soil, drastically reduced the NPs induced toxicity under the application of the T113 strain of <em>T. pseudoharzianum</em>. Plants inoculated with the T113 strain, when grown in NP- NP-contaminated soil, exhibited increased growth, enhanced antioxidant activities, improved photosynthesis, and a decline in damage induced by oxidative stress and the accumulation and translocation of Zn. Moreover, applying the T113 strain also reduced the Zn bioavailability in soil contaminated with NPs. These research findings are an eco-friendly and sustainable solution to the ZnO NP toxicity in the host plants.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"17 ","pages":"Article 100919"},"PeriodicalIF":6.8,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review provides a comprehensive overview of the hormonal and genetic regulatory networks that control leaf structure and specifically LA. It highlights the role of major phytohormones pathways, including brassinosteroids (BR), auxin (IAA), gibberellins (GA), and cytokinins (CKs), with an emphasis on their roles in shaping leaf architecture. BR signaling, in particular, emerges as a central hub, coordinating developmental responses through extensive crosstalk with IAA, GA, and other signaling cascades. Additionally, this review also explores how environmental constraints interact with hormonal and transcriptional dynamics of these pathways to modulate LA, highlighting the complex interplay between intrinsic genetic programs and external conditions. Overall, this review explores current insights into the key genes, signaling pathways, molecular networks, and diverse environmental factors involved in LA regulation.

Our findings showed that <em>N. benthamiana SIZ1</em> (<em>NbSIZ1</em>) mutants exhibited delayed symptom development when challenged with TSWV, indicating reduced susceptibility to TSWV infection. The mutations in the <em>SIZ1</em> gene appeared to activate salicylic acid (SA) signaling pathways, leading to increased SA accumulation and the establishment of constitutive defense responses.

Among these, deepwater rice (DWR) is the one which is cultivated in very limited places in the world, to such an extent that no other crops can coexist in this particular ecosystem. Evolutionarily, rice has adapted to deep water ecology with some unique anatomical, morphological, physiological, and molecular characteristics. Understanding the mechanisms of survival in the deepwater ecosystem is crucial for identifying genes/quantitative trait loci (QTLs) to develop superior DWR with higher yield and subsequent introgression through marker-assisted breeding approaches. Phenotyping studies have mostly been conducted at 6 to 8 leaf stages, whereas deepwater flood typically begins around one month into the late vegetative stage. More attention is needed to conduct research on DWR at late vegetative or reproductive stages, as well as the factors that determine the threshold level of dissolved O₂ in water which triggers anatomical modifications necessary for efficient gas exchange between aerial and submerged plant organs. More investigations are needed to identify novel genes, proteins, and metabolites regulating tolerance underwater and improve deepwater flood tolerance ability. The unique adaptations of DWR may also be associated with novel alleles related to traits such as nutritional quality and compatibility with natural farming practices. In this article, we provide a comprehensive analysis of recent research findings on unique features of DWR and its adaptation to grow under deepwater conditions, high-yielding DWR varieties developed by rice breeders, and genomic resources such as QTLs, genes, and miRNAs responsible for deepwater adaptation. We also highlight the research gaps as well as a future line of work collectively in this article.

Here, we presented the chromosome-level genome assembly of the <em>Focn</em> race 1 strain FGL03-6 via a single-molecule real-time sequencing platform, resequenced the genomes of 23 strains belonging to races 1 and 2, and performed genome-wide identification of <em>Focn</em> effectors using multiomics data generated from the <em>Focn</em>-cabbage interaction.

The use of nanomaterials in commercially available products is rapidly expanding, with significant applications in agriculture and phytoremediation. Current advancements in nanotechnology have introduced iron nanoparticles (Fe-NPs) as a promising approach to enhance crop resilience against stress conditions. Iron (Fe) plays a critical role in photosynthesis, enzyme activation, chlorophyll synthesis, and oxidative stress management, which are pivotal to plant response against water stress. Due to high surface area, small size, and controlled reactivity, Fe-NPs exhibit exceptional advantages over traditional Fe sources, viz., improved bioavailability and nutrient uptake. The current review explores Fe-NP's potential to mitigate the adverse effects of water stress in crop plants by activating various beneficial mechanisms, including improvement in antioxidant defence, osmotic adjustment, and modulating stress related to phytohormones. Particularly, Fe-NPs improve water use efficiency (WUE) and root development, facilitating water and nutrient uptake under stress conditions. Moreover, Fe-NPs assist in antioxidant enzyme regulation, which reduces the accumulation of reactive oxygen species (ROS), thereby reducing oxidative damage and sustaining the metabolic activities of plants under limited water availability.
