    Background Soybean is a fundamental oilseed crop, recognized for its notable protein and oil levels. Tyrosine Sulfation (PSY) genes play an essential role in plant growth, development, and responses to stress. However, the precise functions and mechanisms regulated by PSY are still being explored. Currently, there is insufficient information on the PSY gene family in soybean. Therefore, this study conducted a comprehensive genome-wide survey to detect and PSY family members were categorized in soybean. Results The phylogenetic analysis revealed that PSY family was categorized into nine distinct groups. Further, we precisely mapped the locations of the 12 GmPSY genes across seven soybean chromosomes. Examination of gene duplication revealed six pairs of duplicated genes within the PSY gene family in soybean. A consistent gene structure pattern was observed among GmPSY gene family members. The alignment of GmPSY protein amino acid sequences revealed a conserved PSY domain present in all proteins. Furthermore, RNA-seq data from the Soybean Expression Atlas revealed varying expression patterns of GmPSY genes across different tissues. To validate the expression profiles, qRT-PCR analysis was performed on selected GmPSY genes using root tissues from contrasting soybean accessions. In addition, identified eight out of the 12 GmPSY genes as targets for ten specific miRNAs. Moreover, we constructed a protein-protein interaction network to explore the connections between GmPSY and other soybean proteins. Conclusion Thus, these discoveries lay a robust groundwork for future research aimed at elucidating the specific roles of GmPSY members across different tissues and under various stress conditions in soybean.

    Nanoparticles in plant system: A comprehensive review on their role in diverse stress management and phytohormone signaling
    (Elsevier, 2025-08-19) Kumar, Vinay; Naik, Islavath Suresh; Das, Bimal; Singh, Anupama; Nayak, Prayasi; Mohapatra, Chinmayee; Debnath, Debanjana; Tripathy, Maitreyee; Behera, Kumareswar; Masika, Fred Bwayo; Manohar, Swati; Chung, Sang-Min; Kherawat, Bhagwat Singh; Hemalatha, Mamidi; Kesawat, Mahipal Singh
    Climate variability has led to significant environmental shifts in recent years, placing growing strain on agricultural systems worldwide. These environmental fluctuations have magnified the effects of abiotic and biotic stresses on plants, substantially hampering their growth and lowering crop productivity. To tackle these challenges, there is an urgent need for innovative and effective strategies that promote sustainable agricultural practices. Among emerging technologies, nanotechnology has attracted significant interest for its transformative potential in agriculture. The application of nanoscale materials including nanopesticides, nanofungicides, nanofertilizers, and nanoherbicides offers promising avenues for enhancing crop protection and boost productivity. Nanoparticles (NPs) exhibit unique physicochemical properties that allow for precise and targeted delivery of nutrients and protective agents, thereby improving both the quality and yield of crops under diverse stress conditions. Phytohormone signaling pathways comprise intricate biochemical networks that enable plant hormones to regulate growth, development, and stress responses by transmitting and amplifying precise molecular signals. Recent studies suggest that NPs can alleviate stress-induced damage in plants by modulating phytohormone signaling pathways. However, the complex mechanisms underlying the interactions between NPs and phytohormone biosynthesis remain largely unexplored. This review offers a comprehensive overview of nanoparticle synthesis methods, types, and characterization techniques, with particular emphasis on their potential for mitigating both abiotic and biotic stresses. In addition, the article explores the role of NPs in plant pathology, particularly in disease detection and management. It also highlights emerging evidence on the impact of NPs on phytohormone signaling pathways, which are crucial for improving plant resilience and productivity in stress-prone environments. Thus, nanotechnology holds considerable promise for alleviating stress-related challenges and improving crop yields. A deeper understanding of NP–phytohormone interactions is crucial for developing safe and effective nanotechnological strategies to advance sustainable agriculture
