Homothallism in Nectria galligena

Canadian Journal of Botany, 1986
Cylindrocarpon heteronema (Berk. & Br.) Wollenw. was obtained from perithecia of Nectria galligena Bres. which occurred on the bark of galled branches of Swietenia mahagoni Jacq. collected in Fort Lauderdale, Florida. Hyphal tips were taken from germ tubes of single cells from multiseptate macroconidia and from each cell of germinating ascospores.

Intron polymorphism in small subunit rDNA of Nectria galligena

Microbiology, 1998
PCR amplification of the small subunit (SSU) rDNA gene of 40 isolates of Nectria galligena revealed four length polymorphisms. PCR-RFLP analysis of the SSU rDNA gene divided the isolates into four categories similar, but not identical, to categories identified by Southern-RFLP analysis.

Variability of virulence of Nectria galligena towards northern hardwoods

European Journal of Forest Pathology, 1997
SummaryThe variability of virulence within a Québec population of the fungal pathogen Nectria galligena was studied under greenhouse conditions. Preliminary, small‐scale inoculation of Betula alleghaniensis saplings confirmed that wounds have to be present for successful infection by N.

Molecular detection of Neonectria galligena (syn. Nectria galligena)

Mycological Research, 2002
A pair of primers specific for Neonectria galligena were designed from comparisons of the internal transcribed spacer (ITS) regions 1 and 2 of 32 isolates of diverse origins with sequences from 7 other nectriaceous species: ‘Nectria’ ditissima, N. coccinea, N. coccinea var. faginata, N. punicea, N. fuckeliana, N. cinnabarina , and N. radicicola.

Notes on the canker fungus (Nectria galligena Bres.)

Transactions of the British Mycological Society, 1927
Summary (1) One method of over-wintering of the apple “canker” fungus (Nectria galligena Bres.) is by the formation of perithecia upon shrivelled fruits. (2) The Fusarium stage of “canker” (Fusarium Willkommii Lindau) is responsible for an “eye rot” of Worcester Pearmain. (3) Evidence is brought forward to show that one case of wilting of

Effects of Temperature, Relative Humidity, And Desiccation on Germination of Nectria Galligena Conidia

Mycologia, 1975
Conidia of Nectria galligena Bres. are the important infective propagules in the epidemiology of European apple canker in California. However, little is known about the effects of temperature and relative humidity on conidial germination and survival. Various authors (2, 3, 5) indicate that conidia are strictly water-dispersed and that several hours of

Photoinduction des périthèces du Nectria galligena : production et activité photomorphogène des mycosporines

Canadian Journal of Botany, 1983
Mycosporin I yield of Nectria galligena Bres. in response to duration, intensity, and spectral quality of illumination were evaluated by high-performance liquid chromatography (HPLC). Duration and nature of irradiation were essential light factors for an increase of mycosporin content in the mycelium. The most effective wavelengths were 320, 370, 420,
