The pine-infesting weevils are known to be effective vectors of ophiostomatoid fungi. To understand more about fungal virulence of these fungi, inoculation studies were conducted on Scots pine (Pinus sylvestris L.).

Mycobiota associated with Hylurgops palliatus (Gyll.) on Pinus sylvestris L. in Poland
The assemblage and abundance of fungal species associated with Hylurgops palliatus on Pinus sylvestris, were studied in Poland. Fungi were isolated from beetles of H. palliatus and their galleries collected from three populations.

Study of a sterol esterase secreted by Ophiostoma piceae: Sequence, model and biochemical properties [PDF]
An extracellular sterol esterase from Ophiostoma piceae efficiently hydrolyzes sterol esters, triglycerides and p-nitrophenol esters. cDNA was screened with a probe obtained by PCR using as primers oligonucleotides corresponding to the N-terminal and internal mature enzyme sequences and complete sequence was obtained by 3' rapid amplification of cDNA ...

Production of protoplasts from cultures of Ophiostoma picea
A method is described for producing viable protoplasts from germinating conidia (germlings) of Ophiostoma picea. The use of MgSO4-based osmotic stabilizers significantly improved protoplast release, as did the use of 20-h-old germlings. Protoplast release rates also increased with higher enzyme concentration and incubation times, but there were ...

Some enzymes that belong to the Candida rugosa-like lipase family (abH03. 01) combine the activities of lipases and sterol esterases. Thus, they can act on water-insoluble carboxylic esters releasing long-chain fatty acids but also on sterol esters ...

Ophiostomatoid fungi exhibit a complex relationship with bark beetles; exhausting of host tree defenses is traditionally regarded as one of the key benefits provided to beetle vectors. Ophiostoma bicolor is one of the dominant species of the mycobiota associated with Ips genus bark beetles which infect the spruce trees across the Eurasian continent ...

Abstract A new species in the Ophiostoma piceae complex was isolated from bark beetles and beetle galleries infesting Japanese larch in Japan, and was described as Ophiostoma sugadairense . Phylogenetic analyses of the internal transcribed spacer of the nuclear ribosomal RNA genes region, partial β-tubulin, and elongation factor-1α genes revealed ...
