image indicating the health of normal (top) and diseased (bottom) leaves of Torreya taxifolia (the Florida torreya or stinking yew), an endangered conifer endemic to Florida and Georgia. A close relative of the torreya, the Pacific yew Taxus brevifolia, produces the potent anti-cancer drug taxol — so the torreya's rapid decline to the scant 1 500 trees alive today is of even greater concern tha...
Genetic linkage map construction and QTL identification of juvenile growth traits in Torreya grandis
The Torreya Guardians are trying to save the Florida torreya (Torreya taxifolia Arn.) from extinction (Barlow & Martin 2004). Fewer than 1000 individuals of this coniferous tree remain within its native distribution, a 35-km stretch of the Apalachicola River, and these trees are not reproducing (Schwartz et al. 2000). Even if the Florida torreya was not declining toward extinction, the species ...
Smith, J. A., O’Donnell, K., Mount, L. L., Shin, K., Peacock, K., Trulock, A., Spector, T., Cruse-Sanders, J., and Determann, R. 2011. A novel Fusarium species causes a canker disease of the critically endangered conifer, Torreya taxifolia. Plant Dis. 95:633-639. A canker disease of Florida torreya (Torreya taxifolia) has been implicated in the decline of this critically endangered species in i...
During a survey for pathogens of Florida torreya (Torreya taxifolia) in 2009, a novel Fusarium species was isolated from cankers affecting this critically endangered conifer whose current range is restricted to northern Florida and southwestern Georgia. Published multilocus molecular phylogenetic analyses indicated that this pathogen represented a genealogically exclusive, phylogenetically dist...
The relationship between linkage disequilibrium (LD) and recombination fraction can be used to infer the pattern of genetic variation and evolutionary process in humans and other systems. We described a computational framework to construct a linkage-LD map from commonly used biallelic, single-nucleotide polymorphism (SNP) markers for outcrossing plants by which the decline of LD is visualized w...
