Degradation of benzoic acid by Nectria galligena Bres. in vitro and in vivo

Physiological Plant Pathology, 1973
Abstract The concentration of benzoic acid in the diseased area of immature Bramley's Seedling apple fruits inoculated with Nectria galligena decreased as the arrested lesions expanded into progressive rots, and none was detected in natural canker rots. Benzoic acid was not degraded in healthy apple tissue, even after prolonged incubation.

Biochemical Changes in Cultures of Nectria galligena during the Autolytic Phase of Growth

Annals of Botany, 1970
Some biochemical changes occurring in cultures of Nectria galligena during its autolytic phase of growth have been investigated. In nitrate-grown and autolysed cultures of this fungus the degree of autolysis amounted to 57 per cent. The amount of mycelial lipids decreased continuously with the age of the culture.

Biocontrol ofNectria galligenainfection of pruning wounds on apple shoots

Journal of Horticultural Science, 1979
SummaryThe antagonism of micro-organisms towards Nectria galligena in vitro showed poor correlation with their field performance as wound protectants. Inoculating pruning cuts with micro-organisms prior to infection by N. galligena gave protection equivalent to that obtained with benomyl, but with marked reductions in lesion length and spore output.

The biosynthesis of benzoic acid in Bramley's Seedling apples infected by Nectria galligena Bres

Physiological Plant Pathology, 1975
Abstract Radioactive benzoic acid was synthesized from glucose-14C and l -phenylalanine-14C in apples infected with Nectria galligena and in apples infused with protease extracted from tissue rotted by N. galligena. Phenylalanine ammonia-lyase (PAL) activity was rapidly induced in apples infused with the fungal protease but a lag phase occurred ...

Comparative Spore Morphology and Pathogenicity of Four Florida Isolates of Nectria galligena

Plant Disease, 1988
Barnard, E. L., EI-Gholl, N. E., and Gilly, S. P. 1988. Comparative spore morphology and pathogenicity of four Florida isolates of Nectria galligena. Plant Disease 72.973-976. Perithecia of Nectria ga//igena were observed in the field in association with I) stem galls on Cercis canadensis, 2) hypertrophied, roughened, and fissured bark in branch axils ...

Rotting of Apples of the Variety ‘Bramley's Seedling’ by Nectria galligena, Bres.

Nature, 1964
THE first records of fruit rotting by N. galligena were made by Salmon and Wormald in Kent1 and Dillon-Weston in the Wisbech area2, where it occurred on the variety ‘Worcester Pearmain’; it has since been reported as troublesome on a number of dessert varieties in various European countries3–6.

Screening for resistance to Nectria galligena Bres. in cut shoots of apple

Euphytica, 1989
To find a fast and reliable test to assess resistance to Nectria galligena in apple, different methods of inoculation were compared using macroconidia of N. galligena and one-year-old cut shoots from mature trees of Cox's Orange Pippin, IVT 69078-19, James Grieve and Jonathan.

Bioactive Metabolites from the Fungus Nectria galligena, the Main Apple Canker Agent in Chile

Journal of Agricultural and Food Chemistry, 2005
The phytopathogenic fungus Nectria galligena Bres. is the most common canker disease agent of hardwood trees. The terpenoids colletochlorin B, colletorin B, ilicicolin C, E, and F, as well as the phytotoxin alpha,beta-dehydrocurvularin have been isolated from liquid cultures of N.

Microflora of apple leaf scars in relation to infection by Nectria galligena

Transactions of the British Mycological Society, 1973
The fungi present within the senescent tissue of Bramley's Seedling apple leaf scars were isolated and identified. Within a few weeks of leaf fall most scars were colonized by fungi. The most frequent species were host-specific organisms, such as Phoma limitata, Fusarium lateritium and Phomopsis mali and common saprophytes, notably Aureobasidium ...

The control of apple canker (Nectria galligena) in a young orchard with established infections

Annals of Applied Biology, 1975
SUMMARYIn a factorial experiment on canker control the efficiency of phenylmercurie nitrate (PMN) applied at leaf fall, before bud burst or both was compared with the application of dodine, dithianon, triforine, thiabendazole, benomyl or carbendazim in May and June.
