Abstract

Florida torreya (Torreya taxifolia Arn.) is an endangered conifer with a very limited range in the USA: two counties in Florida and one in Georgia, along the Apalachicola River. The species was once abundant in its small native range but suffered a major decline, ~99% loss, in the late 1950s to early 1960s that is thought to have been caused by a disease. Recently, a canker disease caused by Fusarium torreyae was identified as the primary cause of Florida torreya decline. Efforts to restore and preserve the species in situ and ex situ are hampered by lack of pathogen-free planting stock, and there exists an interest in methods to verify pathogen presence in seeds and seedlings prior to collection and transport for planting. This paper presents a new species-specific diagnostic method that enables detection of F. torreyae and may allow for conservation programmes to ensure germplasm is free of the pathogen prior to planting
