Summary: Studies on traits related to nitrogen-use efficiency (NUE) in wheat cultivars are important for breeding N-efficient cultivars. This study focused on the impact of canopy structure on NUE and found that N-efficient winter wheat varieties have enhanced light transmittance, lower leaf area index, and reduced photosynthetically active radiation.

Summary: Inoculating barley and chickpea with Klebsiella strains capable of producing auxin significantly increased nitrogen use efficiency and nitrogen uptake efficiency, leading to reduced nitrogen fertilizer application. The study showed that the enhanced root surface area contributed to the improved nitrogen acquisition in the plants, with the auxin producers outperforming the non-auxin producer in terms of NUE and NUpE.

Summary: Nitrogen fertilizer is widely used for grain crops, but the low nitrogen use efficiency in cereal crops leads to increased production costs and environmental hazards. Limited studies have focused on roots relevant to nitrogen use efficiency. This review investigates the topic using barley as the primary study plant, highlighting recent progress and study gaps in genetic analysis, as well as factors contributing to nitrogen use efficiency such as root traits, nitrogen transporter activities, and hormonal regulation.

Summary: Using hyperspectral remote sensing to predict nitrogen conversion efficiency and nitrogen internal efficiency in maize hybrids showed promising results, with the ability to statistically differentiate hybrid performance based on these predictions, particularly for nitrogen internal efficiency. Lowering the spatial resolution had an impact on the hyperspectral index values, but did not noticeably affect hybrid differentiation.

Summary: Increasing NUE is crucial for crop yield but faces challenges due to the complexity of nitrogen processes and genetic regulation. Recent research focuses on transcription factors and miRNAs regulating NUE-related genes. Integrating knowledge from model species and exploring genetic variations in wheat may lead to effectively improving NUE levels.

Summary: Biofuels are important for reducing greenhouse gas emissions, but their production results in greenhouse gas emissions such as nitrous oxide. A study in southern South America found that the carinata crop has a high nitrogen uptake capacity, and nitrogen fertilization rates do not significantly affect protein and oil concentrations.

Summary: This study explored the genetic basis of nitrogen use efficiency (NUE) in switchgrass through genome wide association study (GWAS) and identified 19 unique single nucleotide polymorphisms (SNPs) and 32 candidate genes related to NUE. The research provides potential avenues for the development of improved nitrogen use-efficient switchgrass lines.

Summary: By optimizing nitrogen fertilizer application rates, smallholders in China can increase crop yields, improve nitrogen fertilizer use efficiency, and reduce nitrogen pollution in agriculture without changing their operational practices. However, improving management practices and making investments are necessary to produce more grain with less pollution.

Summary: Improving nitrogen use efficiency in crops is crucial for sustainable agriculture and environmental protection. Research has shown that inter-subspecific hybridization in rice can result in F1 hybrids and tetraploids with transgressive NUE, suggesting new possibilities for developing higher NUE rice through heterosis or genetic introgression.

Summary: Nutrient use efficiency (NUE) is a measure of the ratio between crop yield and soil nutrient availability, but it often overlooks the impact of plant traits. Recent research has shown that integrating different plant traits can improve NUE. This includes measuring root nutrient uptake rates and respiration, engineering reductions in photorespiration, and identifying nutrient assimilation pathways. To improve synchrony between plant demand and soil nutrient supply in agricultural systems, it is important to consider plant traits, including crop mixtures. Simulation modeling and multi-objective optimization can further enhance NUE gains beyond selecting based on a single ratio.
