Current opinion and perspectives on the methods for tracking and monitoring plant growth‒promoting bacteria

Since the 1980s, plant growth‒promoting bacteria (PGPB) have been studied as a sustainable alternative to the use of chemical fertilizers to increase crop yields, and effective PGPB have been isolated from diverse plant (e.g., endosphere and phyllosphere) and soil (e.g., rhizosphere) compartments. Despite the promising plant growth promotion results commonly observed under laboratory and greenhouse conditions, the successful application of PGPB...
