Diazotrophic microorganisms are free-living groups of organisms that can convert atmospheric nitrogen (N) into bioavailable nitrogen for plants, which increases crop development and production. The purpose of the current study was to ascertain how diazotrophic plant growth promoting (PGP) Pseudomonas strains (P. koreensis CY4 and P.

Sugarcane is a major crop in tropical and subtropical regions of the world. In China, the application of large amounts of nitrogen (N) fertilizer to boost sugarcane yield is commonplace, but it causes substantial environmental damages, particularly soil, and water pollution. Certain rhizosphere microbes are known to be beneficial for sugarcane production, but much of the sugarcane rhizosphere microflora remains unknown.

Background: Nitrogen is an essential element for sugarcane growth and development and is generally applied in the form of urea often much more than at recommended rates, causing serious soil degradation, particularly soil acidification, as well as groundwater and air pollution. In spite of the importance of nitrogen for plant growth, fewer reports are available to understand the application and biological role of N fixing bacteria to improve N nutrition in the sugarcane plant.

Results: In this study, a total of 350 different bacterial strains were isolated from rhizospheric soil samples of the sugarcane plants.

Nitrogen (N) is the most necessary element in the atmosphere, it is an energetic micronutrient for plant growth and development after water, besides its key role in chlorophyll production, which is crucial for photosynthesis process. Biological nitrogen fixation is measured to be the most potent method to deliver a fixed way of nitrogen to the plants. Plant depends on free-living and symbiotic microbes present in the soil for nitrogen because it cannot be absorbed by the plant itself directly from the atmosphere.

Smut disease is caused by , an important sugarcane fungal pathogen causing an extensive loss in yield and sugar quality. The available literature suggests that there are two types of smut resistance mechanisms: external resistance by physical or chemical barriers and intrinsic internal resistance mechanisms operating at host⁻pathogen interaction at cellular and molecular levels. The nature of smut resistance mechanisms, however, remains largely unknown.

Article Synopsis
  • - The study focused on isolating and examining different bacterial species from the sugarcane rhizosphere for their ability to promote plant growth and fix nitrogen, aiming to find viable biofertilizers as alternatives to chemical fertilizers.
  • - Out of 100 isolated strains, 30 were selected based on their potential to combat sugarcane pathogens and display beneficial traits; notable findings included varying production levels of auxins and nitrogen-fixing activities among these strains.
  • - Two strains, CY4 and CN11, showed the most significant plant growth-promoting traits and were chosen for further analysis, including their biochemical profiles and growth behaviors using advanced molecular techniques like qRT-PCR.
