Search for endophytic diazotrophs in barley seeds
Eight endophytic isolates assigned to Pseudomonas, Azospirillum, and Bacillus genera according to pheno-genotypic features were retrieved from barley seeds under selective pressure for nitrogen- fixers. Genetic relationships among related isolates were investigated through RAPD. Six isolates display...
