Abstract

fetched live from OpenAlex

Biological nitrogen fixation (BNF) by diazotrophic bacteria is one of the oldest and most crucial processes in nature. In this process, bacteria form symbiotic associations with plants, capturing atmospheric nitrogen and making it readily available to them. The diversity of nitrogen-fixing bacteria is vast. Recent advancements in molecular biology techniques have enabled the identification of new genera and species capable of fixing nitrogen and providing other types of nutrients for plants. From an agronomic perspective, this process is fundamental in increasing crop productivity sustainably and -cost-effectively. This review aims to categorize the most recent updates on the diversity of nitrogen-fixing bacteria and showcase the main advances in the genetic improvement of legumes for this characteristic. Recent research has revealed a wide diversity of species applicable to various crops of agronomic interest, and many of these bacteria have been used either alone or in consortium with other microorganisms. This study demonstrates the agricultural potential of these new discoveries and the vast possibilities for expanding research into the diversity of microorganisms responsible for BNF in agriculture.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
