Rhizobacteria from desert plants can alleviate biotic stress and suppress plant diseases, and consequently can enhance plant growth. Therefore, the current study was performed to isolate and identify -associating rhizobacteria based on their antagonistic activity against species and plant growth-promoting properties. Three bacterial isolates were identified as : LDA-1, LDA-2, and LDA-3.

- Azospirillum brasilense is a beneficial rhizobacterium that colonizes plant roots and forms biofilms, which are complex bacterial communities.
- Nitric oxide (NO) serves as a crucial signaling molecule that influences biofilm formation, with A. brasilense Sp245 producing NO through denitrification, which aids in root growth.
- A study found that a mutant strain with impaired NO production formed significantly less biofilm than the wild type, but adding an NO donor reversed this effect, highlighting the positive role of NO in biofilm development.
