The effect of season on infection of Pinus radiata by Dothistroma pini

Forest Pathology, 1981
AbstractBy exposing Pinus radiata seedlings to Dothistroma pini infection in the field over a period of 3 years, the main infection period in the central North Island of New Zealand was found to be from November to February (late spring to late summer). No infection was obtained when the air temperature was below 7°C or when the leaf wetness period was

Neotypification of Dothistroma septosporum and epitypification of D. pini, causal agents of Dothistroma needle blight of pine [PDF]

Forest Pathology, 2016
Summary Dothistroma needle blight (DNB) is one of the most devastating needle diseases on Pinus spp. worldwide. Ever since the description of the causal agent of the disease in Europe in 1911 as Cytosporina septospora, and independently in the USA in ...

Dothistroma pini—Eine Gefahr fürPinus sylvestris?

Forstwissenschaftliches Centralblatt, 1987
Dothistroma pini wurde auf einer ganzen Reihe von Kiefernarten festgestellt. Sporenlange und das gelegentliche Auftreten der HauptfruchtformScirrhia pini belegen das Vorhandensein der var.linearis. Konidien wurden von Marz bis in den November gefunden, besonders zahlreich von April bis Juni. Erstmals, festgestellt wurde das Pathogen aufPinus cembra, P.

A new variety of Dothistroma pini in Kenya

Transactions of the British Mycological Society, 1967
Three varieties of Dothistroma pini Hulbary are distinguished by their spore dimensions. The two varieties described by Thyr & Shaw are retained, with amended values for their conidial dimensions. A third variety, with conidia of intermediate length, is described as var. keniensis . The length of conidia is shown to differ significantly (P linearis

Dothistroma Needle Blight in Slovenia is caused by two cryptic species: Dothistroma pini and Dothistroma septosporum

Forest Pathology, 2013
SummaryDothistroma Needle Blight (DNB) has been known in Slovenia since 1971, but the disease symptoms have intensified in recent years. With this study, the DNB symptoms in Slovenia are for the first time connected to both phytopathogenic Dothistroma species: D. pini and D. septosporum.

Transformation of the fungal forest pathogen Dothistroma pini to hygromycin resistance

Mycological Research, 1997
The forest pathogen Dothistroma pini, which produces the polyketide toxin, dothistromin, was transformed with the pAN7–1 plasmid containing the Escherichia coli hygromycin B phosphotransferase gene (hph). The frequency of hygromycin resistant transformants was 9–48 μg-1 DNA.
