Prescreening Slash Pine and Cronartium Pedigrees for Evaluation of Complementary Gene Action in Fusiform Rust Disease
Stelzer, H. E., Doudrick, R. L., Kubisiak, T. L., and Nelson, C. D. 1999. Prescreening slash pine and Cronartium pedigrees for evaluation of complementary gene action in fusiform rust disease. Plant Dis. 83:385-389. Single-urediniospore cultures of the fusiform rust fungus were used to inoculate seedlings from 10 full-sib families of a five-parent slash pine diallel at two different times in 19...
متن کاملDifferential expression of pine and Cronartium quercuum f. sp. fusiforme genes in fusiform rust galls.
Cronartium quercuum f. sp. fusiforme is the causative agent of fusiform rust disease of southern pines in the United States. This disease is characterized by the formation of woody branch and stem galls. Differential display was used to identify pine genes whose expression is altered by C. quercuum f. sp. fusiforme infection and to identify C. quercuum f. sp. fusiforme genes that are expressed ...
متن کاملDecline in Values of Slash Pine Stands Infected with Fusiform Rust
Losses in product values due tofusi form rust , caused by Cronart ium quercuum (Berk.) Miyabe ex Shiraifi sp. fusiforme, were estimatedfrom four, 2.5-yr-old slash pine, Pinus elliotii Engelm., plantations planted in southern Mississippi over a range of sites with different growth potential and expected rust infection levels. The percentage infected stems rangedfrom 2.5% to 62% at age 2.5. The c...
متن کاملDifferential gene expression in loblolly pine (Pinus taeda L.) challenged with the fusiform rust fungus, Cronartium quercuum f.sp. fusiforme
Cronartium quercuum f.sp. fusiforme is the pathogen that incites fusiform rust disease of southern pine species. To date, a number of host resistance genes have been mapped. Although genomic mapping studies have provided valuable information on the genetic basis of disease interactions in this pine-rust pathosystem, the interaction at the molecular level is poorly understood. To further our und...
متن کاملSurvival of Slash Pine Having Fusiform Rust Disease Varies with Year of First Stem Infection and Severity
Probabilities of death of young slashpine infected byfusiform rustpathogen varied with timing and severity of infection. Trees in nine slashpineplantations varying widely in site quality and initial number oftreesperacre hadsimilarprobabilities ofdeathfrom rust. About 90% oftrees with stem infections in thejirst three growing seasons died by age 15 if the gall spanned more than 50% of the circu...
