Abstract/Contents: | "Population genetics is the study of forces that drive evolutionary changes in populations. These forces, including selection, mutation, recombination, gene flow, and genetic drift, act together to determine the genetic structure of populations. The genetic structure of a plant pathogen population directly determines how it will respond to implemented control practices. Therefore, knowledge of population structure may be used to enhance the durability of resistant cultivars or delay the occurrence of fungicide resistance. Several researchers have analyzed the genetic structure of M. grisea populations associated with rice and other hosts worldwide. Population structure varies from clonal populations with little genetic diversity to highly diverse populations with evidence of genetic recombination. In some cases, analysis of population structure has led to the development of new, effective strategies for managing diseases caused by M. grisea. The current knowledge of genetic structure of M. grisea turfgrass populations will be reviewed, and implications to disease management strategies will be discussed." |
