Zinc (Zn), which is regarded as a crucial micronutrient for plants, and is considered to be a vital micronutrient for plants. Zn has a significant role in the biochemistry and metabolism of plants owing to its significance and toxicity for biological systems at specific Zn concentrations, i.e., insufficient or harmful above the optimal range. It contributes to several cellular and physiological activities of plants and promotes plant growth, development, and yield. Zn is an important structural, enzymatic, and regulatory component of many proteins and enzymes. Consequently, it is essential to understand the interplay and chemistry of Zn in soil, its absorption, transport, and the response of plants to Zn deficiency, as well as to develop sustainable strategies for Zn deficiency in plants. Zn deficiency appears to be a widespread and prevalent issue in crops across the world, resulting in severe production losses that compromise nutritional quality. Considering this, enhancing Zn usage efficiency is the most effective strategy, which entails improving the architecture of the root system, absorption of Zn complexes by organic acids, and Zn uptake and translocation mechanisms in plants. Here, we provide an overview of various biotechnological techniques to improve Zn utilization efficiency and ensure the quality of crop. In light of the current status, an effort has been made to further dissect the absorption, transport, assimilation, function, deficiency, and toxicity symptoms caused by Zn in plants. As a result, we have described the potential information on diverse solutions, such as root structure alteration, the use of biostimulators, and nanomaterials, that may be used efficiently for Zn uptake, thereby assuring sustainable agriculture.
锌(Zn)被视为植物的一种关键微量营养素。由于特定锌浓度下其对生物系统的重要性及毒性,即在最佳范围之外不足或有害时,锌在植物的生物化学和新陈代谢中具有重要作用。它有助于植物的多种细胞和生理活动,促进植物生长、发育和产量。锌是许多蛋白质和酶的重要结构、酶促和调节成分。因此,了解锌在土壤中的相互作用和化学性质、其吸收、运输以及植物对锌缺乏的反应,并制定解决植物锌缺乏问题的可持续策略至关重要。锌缺乏似乎是全球作物中普遍存在的问题,导致严重的产量损失并影响营养品质。考虑到这一点,提高锌的利用效率是最有效的策略,这需要改善根系结构、通过有机酸吸收锌络合物以及植物中的锌吸收和转运机制。在此,我们概述了各种提高锌利用效率并确保作物品质的生物技术。鉴于当前状况,我们努力进一步剖析锌在植物中的吸收、运输、同化、功能、缺乏和毒性症状。结果,我们描述了关于各种解决方案的潜在信息,例如根系结构改变、使用生物刺激剂和纳米材料,这些可有效用于锌的吸收,从而确保可持续农业。
