Ammonium Biology: From Molecular Response to Fertilization

Dear Colleagues,

We would like to invite you to contribute to the Topic "Ammonium Biology: From Molecular Response to Fertilization". Ammonium (NH4+) is a key nitrogen source in soils, yet it can be toxic at moderate concentrations, particularly when used as the primary nitrogen source. To address this challenge, our topic aims to explore how plants respond to ammonium and how genetic breeding or agronomic improvements can enhance crop tolerance to NH4+ fertilizers, thereby improving application efficiency. This topic will cover: (i) Plant Tolerance to Ammonium: Investigating recent advances in enhancing plant tolerance to NH4+ nutrients to improve nitrogen availability and plant health. (ii) Environmental Interactions: Examining the interactions between NH4+ nutrition and environmental factors, such as CO₂ and O₃ levels, droughts, high-temepratures, light, and heavy metal toxicity. (iii) Fertilizer Application and Agronomy: Analyzing the impact of different NH4+-N fertilizer forms and agronomic practices on utilization efficiency and plant tolerance. We seek comprehensive studies, reviews, brief reports, and communications that present the latest findings in plant responses to NH4+, from molecular mechanisms to practical fertilizer applications.. We look forward to your valuable contributions to this exciting and impactful field.
