Dong Y., and Li Q.D., 2024, Screening and functional verification of pine rhizosphere nitrogen-fixing bacteria, Molecular Soil Biology, 15(2): 46-58 (doi: 10.5376/msb.2024.15.0006)

The study investigates the diversity and functionality of nitrogen-fixing bacteria in the rhizosphere of pine trees. The research involved isolating and identifying nitrogen-fixing bacteria from the rhizosphere soil of pine trees and assessing their potential to enhance nitrogen availability and promote plant growth. Various bacterial strains were isolated and screened for nitrogenase activity, with a focus on their genetic and functional diversity. The findings revealed a significant presence of nitrogen-fixing bacteria, including genera such as Burkholderia, Bradyrhizobium, and Pseudomonas, which are known for their nitrogen-fixing capabilities. The study highlights the potential of these bacteria to improve soil fertility and support sustainable forest management practices by enhancing nitrogen cycling in pine ecosystems. The results underscore the importance of microbial interactions in the rhizosphere and their role in promoting plant health and growth.
