Nitrogen-Fixing Rahnella Bacteria Promotes the Growth of Wheat
July 31, 2024| |
Researchers from the Eternal University and partners have discovered that the Rahnella bacteria have nitrogen-fixing capabilities, which can boost the growth of wheat.
Certain bacteria can convert the nitrogen gas from the air into forms that plants can use. However, researchers must first identify which type of bacteria have nitrogen-fixing capabilities and to which crops they can be applied.
Scientists isolated endophytic bacteria from cereal crops in India and screened them for nitrogen fixation. The eight bacterial isolates that exhibited nitrogenase activity were also tested for other growth-promoting traits. The results showed an increase in the total chlorophyll, iron, zinc, and nitrogen content of wheat when it was inoculated with strains of Rahnella bacteria. Their research demonstrates the potential of Rahnella as a bioinoculant or biofertilizer for the growth of cereal crops.
