Detection of Possible Phytophthora pinifolia Infection in Pinus radiata Green Sawn Timber Produced in Chile
A new needle blight disease was observed on Pinus radiata in Chile during 2004. The disease, known in Chile as Daño Foliar del Pino (DFP), stretches southward from the Arauco to Valdivia Provinces, and was present over an area of about 60 000 ha in 2006, with different levels of intensity. The disease is typified by needle infections and exudation of resin at the bases of the needle brachyblast...
متن کاملAFLP analysis reveals a clonal population of Phytophthora pinifolia in Chile.
Phytophthora pinifolia is the causal agent of the recently discovered needle disease of Pinus radiata in Chile, referred to as "Daño Foliar del Pino" (DFP). The genetic structure of the pathogen population is unknown, which hinders our understanding of its appearance and spread in Chile since 2004. In this study, a population of 88 cultures of P. pinifolia isolated from P. radiata at several lo...

متن کاملPhytophthora Species, New Threats to the Plant Health in Korea
Given the lack of a resistant genetic pool in host plants, the introduction of exotic invasive pathogens can result in epidemics that affect a specific ecosystem and economy. Plant quarantine, which is designed to protect endemic plant resources, is a highly invaluable safeguard that should keep biosecurity with increasing international trade and global transportation. A total of 34 species of ...
متن کاملRapid identification of Phytophthora ramorum using PCR-SSCP analysis of ribosomal DNA ITS-1.
AIMS The primary objectives of this study were to determine if a single-strand conformation polymorphism (SSCP) analysis can be used for rapid identification of Phytophthora ramorum, an important quarantine plant pathogen worldwide, and to further assess the potential of the SSCP technique as a taxonomic tool for the genus Phytophthora. METHODS AND RESULTS SSCP of ribosomal DNA internal trans...
