Microbes that increase plant growth


Rhizosphere bacteria have been shown to enhance plant growth. This phenomenon is being investigated so that it can be used to promote the growth of plants on marginal lands.

Regulation of biotechnology for pest management


This webpage details Environmental Protection Agency regulations pertaining to pest management that includes biocontrols.



This website is a general resource for researchers interested in Agrobacterium. Agrobacterium species infect plants. A. tumefaciens is heavily used in biotechnology to move genes into plants.

Agrobacterium: Microbe Wiki


This website provides an excellent overview of the genus Agrobacterium. It contains photos and links to additional information.

Genome of Agrobacterium tumefaciens


A. tumefaciens has been the most widely studied and used Agrobacterium species in the field of biotechnology. Its genome sequence provides a good resource for users to develop additional applications, and a greater understanding of the basic biology, of this strain.



This website contains information on the genomes of Rhizobium and related genera of bacteria. These bacteria fix nitrogen and contribute to the nutrition of plants, thus reducing the need for nitrogen fertilizers.

Rhizobia taxonomy


This webpage provides a roadmap to the naming and characterization of rhizobial strains of bacteria.

Plant viruses


This webpage provides a good primer on viruses that infect plants.

Plant viruses online


This website provides an entry to information on plant viruses, searchable by genus and species name, or by acronym.

Descriptions of plant viruses


This site provides information, and some nice photos, of plant viruses.

Frankia: Microbe Wiki


Frankia are gram positive, nitrogen-fixing bacteria that are important in agriculture.

Frankia genomes


This site is much more than a compilation of genome sequences. It contains information on ecology, physiology and other aspects of Frankia and related organisms.

Erwinia amylovora: Fire blight disease of apple


This bacterium infects apple and pear trees and thus, it causes important economic loss.

Fusarium sporotrichoides


F. sporotrichoides grows on cereal grains and produces potent toxins. Thus, it is important to detect and mitigate against the growth of these fungi on foods.

Plant-microbe interactions: Nature


This page provides a link to a special issue of the journal Nature dealing with plant-microbe interactions; symbiotic, mutualistic, and pathogenic.

Society for Molecular Plant-Microbe Interactions


This society provides links to meetings, jobs and resources in the field of plant-microbial interactions.
