Publication Type: Book / Chapter Publication Acceptance Date: 4/9/1997 Publication Date: N/A Citation: N/A Interpretive Summary: This chapter is the part of a book entitled "Trichoderma and Gliocladium" that addresses the role of antibiotics produced by these two groups of fungi in the biocontrol of plant diseases. It goes into detail about the kinds of antibiotics that are produced by different species within Trichoderma and Gliocladium, and the effects of environment on antibiotic production and activity. It also addresses antibiotics as mechanisms in disease control, and their mode of action. Genetic manipulation of antibiotic production within these fungi and its relation to disease control is also discussed. Final remarks conclude that successful biocontrol agents will be those that make the most efficient use of a number of mechanisms associated with antagonism, and those that can function under a wide range of environmental conditions. Technical Abstract: This book chapter deals with the role of antibiosis in biocontrol, specifically those antibiotics produced by members of the genus Trichoderma that are associated with disease control. These compounds include alkyl pyrones, isonitriles, polyketides, peptaibols, diketopiperazines, sesquiterpenes, and steroids. The chapter also deals with the environmental parameters affecting antibiotic production and activity; antibiotic mechanisms in disease biocontrol and their mode of action; genetic manipulation of antibiotics and disease control; and concluding remarks. The final remarks include an assessment that successful biocontrol agents will be those that make the most efficient use of a number of mechanisms associated with antagonism, and those that can function under a wide range of environmental conditions. |
