Nitrogen uptake efficiency in plants

Nitrogen uptake efficiency (NUE) is a critical trait for plant productivity and sustainability in agriculture. It refers to the ability of plants to absorb and utilize nitrogen from the soil efficiently. NUE is influenced by several factors, including root architecture, mycorrhizal associations, and nitrogen transporters. Plants with high NUE can maintain growth and yield under low nitrogen conditions, reducing the need for synthetic fertilizers. Recent advances in molecular biology have identified genetic loci associated with NUE, paving the way for breeding programs aimed at developing nitrogen-efficient crop varieties. Enhancing NUE is essential for improving food security while minimizing the environmental impact of agricultural practices.
