phytopathogen

Nevertheless, harmful effects of mycoviruses are economically interesting, especially if the fungal host is a phytopathogen and the mycovirus could be exploited as biocontrol agent.

Rhodococcus fascians (known as Corynebacterium fascians until 1984) is a Gram positive bacterial phytopathogen that causes leafy gall disease.

Erwinia psidii is a Gram-negative bacterium and a phytopathogen of the Common Guava (Psidium guajava), causing rot in branches, flowers and fruits.

The bacterial phytopathogen Rhodococcus fascians has been attributed as a cause of fasciation, but many fasciated plants have tested negative for the bacteria in studies, hence bacterial infection is not an exclusive causation.

In the phytopathogen A. tumefaciens, AiiB lactonase acts as a fine modulator that essentially delays the release of lactone OC8-HSL and the resultant number of tumors produced by the pathogen.

Alfalfa mosaic virus (AMV), also known as Lucerne mosaic virus or Potato calico virus, is a worldwide distributed phytopathogen that can lead to necrosis and yellow mosaics on a large variety of plant species, including commercially important crops.
