Pseudomonas Migula 1894 (antagonists)

The genus contains about 200 species of Gram-negative, non-sporulating, rod-shaped and aerobic bacteria. They can have several polar flagellae and produce a green diffusible, fluorescent pigment on certain media.

The genus includes various species and strains which are important as human and animal pathogens or as plant pathogens. However, several species and strains are beneficial with regards to pest and weed management, including some which have antagonistic properties against plant diseases. The latter group is covered on this page.

Antagonistic Pseudomonas species are often referred to as plant growth-promoting rhizobacteria. They excrete or posses substances that trigger induced and unspecific systemic resistance to a large variety of diseases in the host plants.

This page refers to antagonists only, for other groups see:
