Potential role of pathogen signaling in multitrophic plant-microbe interactions involved in disease protection

Article Abstract:

Multitrophic interactions mediate the ability of fungal pathogens to cause plant disease and the ability of bacterial antagonists to suppress disease. An examination of whether a pathogen metabolite functions as a negative signal for bacterial biosynthesis, which can determine the relative importance of biological control mechanisms available to antagonists and which may also influence fungus-bacterium ecological interactions, is made.

Enhancement of chilling resistance on inoculated grapevine plantlets with a plant growth-promoting rhizobacterium, Burkholderia phytofirmans strain PsJN

Article Abstract:

A known plant growth-promoting bacterium, Burkholderia phytofirmans strain PsJN, for its ability to enhance chilling resistance in grapes is tested. This bacterium is capable of epiphytic and endophytic colonization of grapevine tissues and organs and is shown to protect plants against heat stress.

Use of plant growth-promoting bacteria for biocontrol of plant diseases: Principles, mechanisms of action, and future prospects

Article Abstract:

The advances of plant growth-promoted bacteria (PGPB) interaction research are surveyed focusing on the principles and mechanisms of action of PGPB, both free-living and endophytic bacteria. Their use or potential use for the biological control of plant diseases is discussed.
