Isolations from the redbay ambrosia beetle, Xyleborus glabratus, confirm that the laurel wilt pathogen, Raffaelea lauricola, originated in Asia
The results support the hypothesis that R. lauricola was introduced into the USA in the mycangium of the redbay ambrosia beetle, Xyleborus glabratus, which is native to Asia and suggest that the X. glabRatus population established in USA originated in another part of Asia. Expand
The rust genus Frommeëlla revisited: a later synonym of Phragmidium after all
Frommeëlla (Phragmidiaceae, Pucciniales, Basidiomycota), which currently includes two species and is typified by F. tormentillae, causes rust on members of tribe Potentilleae (Rosaceae), and should be considered to be a later generic synonym of Phragmidium. Expand
Bur oak blight, a new disease on Quercus macrocarpa caused by Tubakia iowensis sp. nov.
A newly recognized, late-season leaf disease of Quercus macrocarpa (bur oak) has become increasingly severe across Iowa and in neighboring states since the 1990s. Vein necrosis and leaf death mayExpand
Genetic Variation in Native Populations of the Laurel Wilt Pathogen, Raffaelea lauricola, in Taiwan and Japan and the Introduced Population in the United States.
It is suggested the importance of preventing a second introduction of R. lauricola to the United States, which could introduce the opposite mating type and allow for genetic recombination. Expand
Stem Canker of Giant Dogwood (Cornus controversa) Caused by Fusarium lateritium in Korea.
In May 2012, a stem canker was observed on a ~20-year-old giant dogwood (Cornus controversa) in Suwon, Gyeonggi Province, South Korea, which consisted of necrotic lesions on stem bark with orangeExpand
First Report of Uromyces acuminatus on Honckenya peploides, the Endangered Seabeach Sandwort.
To the knowledge, this is the first report of U. acuminatus on the genus Honckenya, and the resulting sequences identical to that of H. peploides. Expand
Antagonistic Bacillus species as a biological control of ginseng root rot caused by Fusarium cf. incarnatum
The bacterial isolate B2-5 has good potential as a microbial agent for the biocontrol of the ginseng root rot caused by F. cf. Expand
Metabolic response induced by parasitic plant-fungus interactions hinder amino sugar and nucleotide sugar metabolism in the host
The findings indicate that altered metabolic responses that occur during fungal parasitism can cause deficiency in substrates in pivotal pathways and thereby trigger pathological symptoms in the plant host. Expand
Tubakia subglobosa Causes Leaf Spots on Ring-Cupped Oak Trees in Korea
These macro- and micromorphological traits closely fitted to those of Tubakia subglobosa (Diaporthales), which was described from Japan, thus fulfilling Koch’s postulates. Expand
The rust fungus Gymnosporangium in Korea including two new species, G. monticola and G. unicorne
Phylogenetic analyses show that species of Gymnosporangium form a monophyletic group with strong bootstrap support within the rust fungi, and phenotypic characters mapped onto the phylogenetic tree show that teliospore length followed by telia shape and telia length are conserved. Expand
