Analyzing Nodule Occupancy Using Antibiotic-Resistant Markers
Antibiotic-resistant marked strains of rhizobia may be identified by their ability to grow on media containing antibiotics. The antibiotic marker technique is applied in ecological studies where strain identification is not possible by serology due to cross-reactions of the strains, or because of unavailability of antisera. Antibiotic markers also provide useful confirmatory data.
