Terpene arms race in the Seiridium cardinale – Cupressus sempervirens pathosystem
The canker-causing fungus Seiridium cardinale is the major threat to Cupressus sempervirens worldwide. We investigated the production of terpenes by canker-resistant and susceptible cypresses inoculated with S. cardinale, the effect of these terpenes on fungal growth, and the defensive biotransformation of the terpenes conducted by the fungus. All infected trees produced de novo terpenes and st...
متن کاملSequence and simple-sequence repeat analyses of the fungal pathogen Seiridium cardinale indicate California is the most likely source of the cypress canker epidemic for the Mediterranean region.
Seiridium cardinale is the pathogenic fungus of unknown origin responsible for a world pandemic known as cypress canker affecting several species of Cupressaceae in both the Northern and Southern Hemisphere. In this study, a comparative genetic analysis of worldwide populations was performed using sequence analysis of a portion of the ?-tubulin locus and seven polymorphic simple-sequence repeat...
متن کاملLinkage mapping of the Mediterranean cypress, Cupressus sempervirens, based on molecular and morphological markers.
Gene mapping for a Cupressus species is presented for the first time. Two linkage maps for the Mediterranean cypress (Cupressus sempervirens) varieties, C. sempervirens var. horizontalis and C. sempervirens var. pyramidalis, were constructed following the pseudo-testcross mapping strategy and employing RAPD, SCAR and morphological markers. A total of 427 loci (425 RAPDs, two SCARs) repres...
متن کاملCypress canker: a pandemic in progress.
Over the past 70 years a destructive blight of Cupressus macrocarpa and other Cupressaceae, caused by Seiridium cardinale, has spread worldwide from California, devastating forests, plantations, and ornamental cypresses. The epidemic has been particularly severe in the Mediterranean region, on C. sempervirens. A similar destructive blight induced by Lepteutypa cupressi, which caused serious los...
