attack pattern of platypus koryoensis (coleoptera: curculionidae: platypodinae) in relation to crown dieback of mongolian oak in korea.	the ambrosia beetle, platypus koryoensis (murayama), vectors the korean oak wilt (kow) pathogen, raffaelea quercus-mongolicae k.h. kim, y.j. choi, & h.d. shin, in korea, which is highly lethal to mongolian oak, quercus mongolica fisch., and is considered a major threat to forest ecosystem health. we characterized the attack pattern of p. koryoensis along the lower trunk of 240 mongolian oaks in relation to tree decline symptoms on mt. uam in gyeonggi-do province, korea during june-july 2009. for ...	2011	22217750
filamentous fungi isolated from platypus koryoensis, the insect vector of oak wilt disease in korea.	the ambrosia beetle, platypus koryoensis, is a serious pest of oak trees in korea. in this study we investigated filamentous fungi present in the body of the beetle. fourteen genera of filamentous fungi belonging to ascomycota and basidiomycota were isolated. among the isolated fungi, some were able to produce wood degrading enzymes. this is first report of fungi associated with p. koryoensis.	2011	22783124
the effect of raffaelea quercus-mongolicae inoculations on the formation of non-conductive sapwood of quercus mongolica.	in korea, mass mortality of quercus mongolica trees has become obvious since 2004. raffaelea quercus-mongolicae is believed to be a causal fungus contributing the mortality. to evaluate the pathogenicity of the fungus to the trees, the fungus was multiple- and single-inoculated to the seedlings and twigs of the mature trees, respectively. in both the inoculations, the fungus was reisolated from more than 50% of inoculated twigs and seedlings. in the single inoculations, proportions of the transv ...	2014	25071395
phylogeny of ambrosia beetle symbionts in the genus raffaelea.	the genus raffaelea was established in 1965 when the type species, raffaelea ambrosia, a symbiont of platypus ambrosia beetles was described. since then, many additional ambrosia beetle symbionts have been added to the genus, including the important tree pathogens raffaelea quercivora, raffaelea quercus-mongolicae, and raffaelea lauricola, causal agents of japanese and korean oak wilt and laurel wilt, respectively. the discovery of new and the dispersal of described species of raffaelea to new a ...	2014	25457944
yeast associated with the ambrosia beetle, platypus koryoensis, the pest of oak trees in korea.	oak tree death caused by symbiosis of an ambrosia beetle, platypus koryoensis, and an ophiostomatoid filamentous fungus, raffaelea quercus-mongolicae, has been a nationwide problem in korea since 2004. in this study, we surveyed the yeast species associated with p. koryoensis to better understand the diversity of fungal associates of the beetle pest. in 2009, a total of 195 yeast isolates were sampled from larvae and adult beetles (female and male) of p. koryoensis in cheonan, goyang, and paju; ...	2015	26839506
genetic diversity and population structure of raffaelea quercus-mongolicae, a fungus associated with oak mortality in south korea.	raffaelea quercus-mongolicae is a fungus associated with oak wilt and deemed to cause extensive oak mortality in south korea. since the discovery of this fungus on a dead mongolian oak (quercus mongolica) in 2004, the mortality continued to spread southwards in south korea. despite continued expansion of the disease and associated significant impacts on forest ecosystems, information is lacking about the origin and genetic diversity of r. quercus-mongolicae. restriction-site-associated dna (rad) ...	2016	27087782
draft genome sequence of the fungus associated with oak wilt mortality in south korea, raffaelea quercus-mongolicae kacc44405.	the fungus raffaelea quercus-mongolicae is the causal agent of korean oak wilt, a disease associated with mass mortality of oak trees (e.g., quercus spp.). the fungus is vectored and dispersed by the ambrosia beetle, platypus koryoensis here, we present the 27.0-mb draft genome sequence of r. quercus-mongolicae strain kacc44405.	2017	28839019
characterization of bacillus amyloliquefaciens da12 showing potent antifungal activity against mycotoxigenic fusarium species.	in an attempt to develop a biological control agent against mycotoxigenic fusarium species, we isolated bacillus amyloliquefaciens strain da12 from soil and explored its antimicrobial activities. da12 was active against the growth of mycotoxigenic f. asiaticum, f. graminearum, f. proliferatum, and f. verticillioides both in vitro and in planta (maize). further screening using dual culture extended the activity range of strain da12 against other fungal pathogens including botrytis cinerea, collet ...	2017	29018313
