During a pinewood nematode survey in 2011, a dead pitch pine (Pinus rigida) was found in Daejeon city, Korea. Samples were taken from several regions of the trunk and nematodes were extracted from the wood samples by a modified Baermann funnel method (1). Recovered nematodes were then cultured on

The basidiomycete Heterobasidion annosum (Fr.) Bref. (=Fomes annosus (Fr.) Cooke), one of the most important pathogens in coniferous forests in Europe, Asia, and North America, causes root and butt rot. H. annosum was first recorded on Pinus pinaster Ait. (commonly known as Maritime pine) in France

An elevated incidence of the fungal genus Fusarium was ascertained during a health quality analysis of a batch of Pinus elliottii Englm. seeds obtained from the Florestas Institute for Agricultural and Forest Research (Fundação Estadual de Pesquisa Agropecuária [FEPAGRO] Florestas) in Santa Maria

Pinus halepensis Mill. is a pine native to the Mediterranean region that is generally located from sea level up to an altitude of 200 meters. In July 2012, extensive leaf yellowing and scorching were observed on the foliage of two specimens of P. halepensis in a public park of Alassio municipality,

During the winter of 2003-2004, dieback symptoms were observed on Pinus radiata and P. pinaster in pine nurseries in Asturias (northern Spain). Small groups of affected seedlings appeared randomly distributed throughout the nurseries. The seedlings died rapidly, showing basal needle dieback, stem

In the fall of 2009, damping-off of Pinus radiata seedlings was observed in a pine nursery in Sant Feliu de Buixalleu, Girona Province, northeastern Spain. Plants exhibited needle blight, extensive root necrosis, and root death. Root sections of symptomatic plants were cut, washed under running tap

In November 2010, pitch canker disease was first discovered on Pinus sylvestris var. mongolica Litv. from Daxinganling region in Inner Mongolia Province, China, resulting in severe dieback and bark cracking on the host, accompanied by resin flowing profusely from cankers on the infected branches,

Pinus thunbergii Parl., known as black pine, is a pine native to coastal areas of Japan and Korea. Because of its resistance to pollution and salt, it is planted as windbreakers along the coast. In March 2010, needle blight symptoms were found on several trees of black pine in Naju, southern Korea.

One full length (PrCESA10) and seven other cDNA clones (PrCESA2, 3, 5-8, 11) encoding cellulose synthases (CESAs) were isolated from the coniferous gymnosperm Pinus radiata. PrCESA10 encodes a protein predicted to contain the same domains and regions as angiosperm CESA genes: a zinc finger domain, a

Since 2005, pitch canker symptoms have been observed in Apulia (southern Italy, 41°27'42.84″N, 15°33'0.36″E) on numerous trees of Pinus halepensis and P. pinea in urban parks and gardens. Trees showed crown decline as a consequence of dieback of twigs and branches and withering of needles. Bleeding

Dikaryotic strains of Neolentinus suffrutescens were obtained from crosses of 12 monosporous isolates. The monosporous breeding stocks and the crosses were evaluated on potato dextrose agar with a wood infusion of Pinus montezumae and growth rates at 12 days of incubation were determined. Eight

Maximum accumulation of Pin m III protein in western white pine (Pinus monticola Dougl. ex D. Don) needles occurred during the winter months. To characterize Pin m III, an expression cDNA library from poly(A)+ mRNA of needles was immunoscreened and the full length cDNA was cloned. An open reading

A dieback associated with resinous branch and main stem cankers was observed on two spruce pine (Pinus glabra Walt.) trees in Lee County, Alabama in July 2002. Xylem tissues beneath the cankers were resinsoaked as is characteristic of pitch canker on other southern pine species. Surface-sterilized

Diplodia pinea is a latent, opportunistic pathogen of Pinus and other coniferous species, including Pseudotsuga menziesii (3). The fungus causes twig blight, branch cankers, tree and seedling collar rot, root rot, and can also infect cones (1). D. pinea has often been reported causing tip and shoot

Several factors affect the vegetative growth of fungi, such as temperature, pH, and culture medium. In addition to mycelial growth, these factors affect metabolite production. There are limited studies that have identified the metabolites produced by the fungus Bjerkandera adusta, which have
