Differential 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 کاملNuclear behavior during basidiospore germination in Cronartium quercuum f. sp. fusiforme
Nuclear behavior during basidiospore germination in Cronartiunz quercuum f. sp. fusiforme was examined on glass slides and host seedlings using 4, 6-diamidino-2-phenylindole staining. Mononucleate basidiospores of Cronartium quercuum f. sp. fusiforme normally were produced following meiosis in the teliospore. However, a subsequent mitotic division often occurred within each basidiospore resulti...
متن کاملEffect of surface wettability on germination and gene expression in Cronartium quercuum f. sp. fusiforme basidiospores
Cronartium quercuum f. sp. fusiforme is an obligate pathogen of pine and oak. Its basidiospores are specifically adapted to recognize and establish infections on the pine host. Depending on environmental cues, the basidiospores can germinate directly, which typically leads to infection of pine, or indirectly, which usually results in formation of secondary basidiospores. We investigated how cha...
متن کاملStability of Slash Pine Families with Major Gene and Partial Resistance to Single-Gall and Mixed-Gall Inocula of Cronartium quercuum fusiforme in Greenhouse Studies
Single-gall and mixed-gall inocula from fusiform rust (Cronartium quercuum fusiforme) galls in field studies were used in greenhouse tests to investigate their pathogenic variability and the temporal and spatial stability of fusiform rust incidence of resistant slash pine (Pinus elliottii var. elliottii) seedlings. Analyses of variance showed significant main effects for families and inocula an...
متن کاملA genomic map enriched for markers linked to Avr1 in Cronartium quercuum f.sp. fusiforme.
A novel approach is presented to map avirulence gene Avr1 in the basidiomycete Cronartium quercuum f.sp. fusiforme, the causal agent of fusiform rust disease in pines. DNA markers tightly linked to resistance gene Fr1 in loblolly pine tree 10-5 were used to classify 10-5 seedling progeny as either resistant or susceptible. A single dikaryotic isolate (P2) heterozygous at the corresponding Avr1 ...
