Natural and beneficial associations between plants and bacteria have demonstrated potential commercial application for several agricultural crops. The sunflower has acquired increasing importance in Brazilian agribusiness owing to its agronomic characteristics such as the tolerance to edaphoclimatic variations, resistance to pests and diseases, and adaptation to the implements commonly used for maize and soybean, as well as the versatility of the products and by-products obtained from its cultivation. A study of the cultivable bacteria associated with two sunflower cultivars, using classical microbiological methods, successfully obtained isolates from different plant tissues (roots, stems, florets, and rhizosphere). Out of 57 plantgrowth-promoting isolates obtained, 45 were identified at the genus level and phylogenetically positioned based on 16S rRNA gene sequencing:42 Bacillus (B. subtilis, B. cereus, B.thuringiensis, B.pumilus,B. megaterium, and Bacillus sp.) and 3 Methylobacterium komagatae. Random amplified polymorphic DNA (RAPD) analysis showed a broad diversity among the Bacillus isolates, which clustered Natural and beneficial associations between plants and bacteria have demonstrated potential commercial application for several agricultural crops.

Random amplified polymorphic DNA (RAPD) analysis showed broad diversity among the Bacillus isolates,which clustered into 2 groups with 75% similarity and 13 subgroups with 85% similarity, suggesting that the genetic distance correlated with the source of isolation. The isolates weralso analyzed for certain growth-promoting activitiesAuxin synthesis was widely distributed among the isolates, with values ranging from 93.34 to 1653.37 µM auxin per µg of protein. The phosphate solubilization index ranged from 1.25 to 3.89, and siderophore index varied from 1.15 to 5.25. From a total of 57 isolates, 3 showed an ability to biologically fix atmospheric nitrogen, and 7 showed antagonism against the pathogen Sclerotinia sclerotiorumThe results of biochemical characterization allowed identification of potential candidates for the developmenof biofertilizers targeted to the sunflower crop.
