The production of certain cell wall-degrading enzymes by Leptosphaeria maculans in culture and in stem canker lesions of oilseed rape

Physiological Plant Pathology, 1985
Abstract Leptosphaeria maculans causes stem canker on oilseed rape (Brassica napus). Studies using sodium polypectate and rape cell wall media show that the pathogen can produce a variety of cell wall-degrading enzymes in liquid culture. There is also an accumulation of cell wall-degrading enzymes in stem canker lesions.

Lesion development in stems of rough‐ and smooth‐barked Eucalyptus nitens following artificial inoculations with canker fungi

Forest Pathology, 2001
A study of lesion development in stems of Eucalyptus nitens following artificial inoculations with canker fungi was carried out on 16‐year‐old plantation trees. In a first trial cambium bark wounds on smooth‐ and rough‐barked trees were inoculated with the mycelium of nine species of canker fungi, including Endothia gyrosa.

Some factors governing mycelial establishment and lesion extension in the larch canker disease

Forest Pathology, 1973
From inoculations on larch trees with mycelium of Trichoscyphella willkommii it was shown that seasonal variation in lesion development was the result of varying ability by the host to limit mycelial spread. Freezing conditions as well as fungal infection were shown to be essential for canker extension and the mechanism was apparently an alternation of

Injection–Infiltration of Attached Grapefruit with Xanthomonas citri subsp. citri to Evaluate Seasonal Population Dynamics in Citrus Canker Lesions

Journal of Phytopathology, 2016
AbstractTo study population dynamics of Xanthomonas citri subsp. citri (Xcc) in citrus canker lesions on fruit, a needle‐free injector was used for infiltration of bacterial inoculum into fruit in situ on mature ‘Ruby Red’ grapefruit (Citrus paradisi Macf.) trees in Florida. Inoculations of Xcc at 105 colony‐forming units (cfu) per ml were conducted in

Bacterial Exudation from Lesions of Asiatic Citrus Canker and Citrus Bacterial Spot

Plant Disease, 1991
When water was added to wells surrounding young lesions of Asiatic citrus canker (caused by Xanthomonas campestris pv. citri) on detached, field-collected leaves of grapefruit, about 10 4 -10 5 bacteria per milliliter were exuded immediately. Bacterial exudation into the water continued at high levels for 24 hr, and cumulative release ranged from 10 5
