Description
Summary:•Biofortification and improved zinc efficiency in plants hold the realistic prospect of combating worldwide Zn malnutrition.•Zinc serves as an irreplaceable structural co-factor for many protein functions in several metabolic processes.•Zinc finger proteins can regulate transcription by DNA-RNA binding effects, protein–protein interactions and RNA metabolism.•As a nutrient management strategy, Zn in a dose dependent manner could prove to be beneficial. The consolidation of numerous novel findings that produce a clear understanding of zinc (Zn) relevance to plant status is significant. The present review elaborates the roles of Zn in plant development and management with an aim to provide an updated picture to the current context of the topic for future studies. The fate of Zn utilization in plants starts with understanding the uptake and movement dynamics of the ion. Its uptake and translocation utilizes the symplastic or apoplastic route which could be influenced by water flow path and advection depending on transpiration rate. Cell membrane transporters can channel Zn ions to epidermal cells. Zinc has ameliorating effects in several plant stresses such as heavy metal toxicity, salinity and drought. Moreover, the transcriptional factors including zinc finger proteins (ZFPs) are involved in plant growth regulation and responses to biotic and abiotic stresses. Finally, the pivotal strategies aimed at optimizing plant Zn nutritional contents mainly target the improvement of plant Zn efficiency, genetic and agronomic biofortification to combat Zn malnutrition in the world.
