Abstract：
Zinc (Zn)- and iron (Fe)-regulating transport-like proteins (ZIPs) are a class of proteins crucial for metal uptake and transport in plants, particularly for Zn and Fe absorption and distribution. These proteins ensure the balance of trace elements essential for plant growth, development, and metabolic activities. However, the role of the rice (Oryza sativa) OsZIP gene family in manganese (Mn) and selenium (Se) transport remains underexplored. This research conducted an all-sided analysis of the rice OsZIPs and identified 16 OsZIP sequences. Phylogenetic analysis categorized the OsZIPs predominantly within the three subfamilies. The expression levels of OsZIPs in rice root and leaf subjected to Mn and Se toxicity stress were examined through quantitative real-time PCR (qRT-PCR). The findings revealed significant differential expression of many OsZIPs under these conditions, indicating a potential regulating effect in the response of rice to Mn and Se toxicity. This work lays a foundation for further functional studies of OsZIPs, enhancing our understanding of the response mechanisms of rice to Mn and Se toxicity and their roles in growth, development, and environmental adaptation.
摘要：
锌（Zn）-和铁（Fe）-调节运输样蛋白（ZIP）是一类对植物中金属吸收和运输至关重要的蛋白质，特别是对于Zn和Fe的吸收和分布。这些蛋白质确保植物生长所必需的微量元素的平衡，发展,和代谢活动。然而,水稻（Oryzasativa）OsZIP基因家族在锰（Mn）和硒（Se）运输中的作用仍未得到充分研究。本研究对水稻OsZIP进行了全面分析，并鉴定了16个OsZIP序列。系统发育分析将OsZIP主要归入三个亚科。通过定量实时PCR（qRT-PCR）检测了受Mn和Se毒性胁迫的水稻根和叶中OsZIPs的表达水平。研究结果揭示了在这些条件下许多OsZIP的显著差异表达，表明水稻对Mn和Se毒性的反应具有潜在的调节作用。这项工作为进一步研究OsZIPs的功能奠定了基础，加强我们对水稻对锰和硒毒性的响应机制及其在生长中的作用的理解，发展,和环境适应。
