Bacterial endophytes in agricultural crops
Historically, endophytic bacteria have been thought to be weakly virulent plant pathogens but have recently been discovered to have several beneficial effects on host plants, such as plant growth promotion and increased resistance against plant pathogens and parasites.
Endophytic and ectophytic potato-associated bacterial communities differ in structure and antagonistic function against plant pathogenic fungi.
Spectrum and Population Dynamics of Bacterial Root Endophytes
The major factors influencing bacterial diversity and colonisation have been discussed and their potential to manage endophytic communities towards increased benefits for plants and human health have been outlined.

Nine isolates belonging to Pseudomonas and Streptomyces species were found to control both fungal pathogens and M. incognita and were therefore considered as promising biological control agents.
Biological control using microbial pathogens, endophytes and antagonists.
Control of plant pathogenic fungi with bacterial endophytes
A better understanding of the underlying mechanisms and their regulation in response to environmental factors, but also of the population dynamics of antagonistic bacterial endophytes within the plant is required.

Effects of arbuscular mycorrhizal fungi and a non-pathogenic Fusarium oxysporum on Meloidogyne incognita infestation of tomato
Combined application of the AM fungus and Fo162 enhanced mycorrhization of tomato roots but did not increase overall nematode control or plant growth.
