First Report of a Rust Disease on Ohia Caused by Puccinia psidii in Hawaii.
This rust disease may pose a formidable threat to Myrtaceous species that make up the native Hawaiian forests and are grown as ornamental plants or for the production of wood chips. Expand
A taxonomic revision of Phytophthora Clade 5 including two new species, Phytophthora agathidicida and P. cocois
Two new species in Clade 5 are presented on the basis of genetic and morphological differences and host speciﬁcity, and an authentic ex-holotype culture of Phytophthora castaneae is designated and P. heveae is lectotypified and epitypified. Expand
Morphological distinctions between Phytophthora capsici and P. tropicalis sp. nov.
Phytophthora isolates with deciduous long- pedicellate sporangia can be separated into two groups by isozyme analyses, but an apparent overlap in morphological characteristics was previously deemed… Expand
Preserving accuracy in GenBank
GenBank, the public repository for nucleotide and protein sequences, is a critical resource for molecular biology, evolutionary biology, and ecology. While some attention has been drawn to sequence… Expand
Pathogenicity, Internal Transcribed Spacer-rDNA Variation, and Human Dispersal of Ceratocystis fimbriata on the Family Araceae.
It appears that adaptations to the family Araceae have evolved more than once in the C. fimbriata complex, as inoculations of three species of Araceae showed that isolates from all three groups are pathogenic to these three hosts. Expand
Rapid Nuclear Staining of Rhizoctonia Solani and Related Fungi with Acridine Orange and with Safranin O
Characterization of Fusarium diseases on commercially grown orchids in Hawaii
New information concerning Dendrobium orchid pathogens is provided and a much wider host range than previously recognized is suggested for the five Fusarium species recovered from tissue with symptoms, which represent a significant challenge to orchid production in Hawaii. Expand
A Recurrent Epiphytotic of Guava Rust on Rose Apple, Syzygium jambos, in Hawaii.
A Neotropical rust of the Myrtaceae, Puccinia psidii Winter, was first discovered in Hawaii on potted Metrosideros polymorpha Gaud on Oahu in April 2005 and spread quickly, and by January 2006, severe outbreaks of this rust occurred statewide on new leaves of Syzygium jambos, or rose apple. Expand
Tracking the distribution of Puccinia psidii genotypes that cause rust disease on diverse myrtaceous trees and shrubs
The objectives of this study were to estimate genetic diversity within and among populations across the species native range as well as areas of recent introduction, evaluate possible pathways of spread, and predict geographic areas that are climatically suitable in order to predict risk of invasion.
