| dynamics of introduced populations of phragmidium violaceum and implications for biological control of european blackberry in australia. | phragmidium violaceum causes leaf rust on the european blackberry (rubus fruticosus l. aggregate). multiple strains of this pathogen have been introduced into southern australia for the biological control of at least 15 taxa of european blackberry, a nonindigenous, invasive plant. in climates conducive to leaf rust, the intensity of disease varies within and among infestations of the genetically variable host. genetic markers developed from the selective amplification of microsatellite polymorph ... | 2008 | 18641150 |
