... Early blight is a common disease of Solanaceae crops worldwide. The occurrence of Alternaria spp. was studied during three epidemics on tomato in northwestern Algeria. Alternaria was detected in more than 80 % of the diseased plant samples and accounted for more than 50 % of the total fungal isolates recovered from these samples. Morphological and molecular investigations revealed that small-spore ...

Abstract:
... Long-lasting viable fungal spores are one of the important aspects in emergence, spread and disease development of pathogenic fungi. We developed a rapid and miniaturized system using Alamar Blue (resazurin dye; 7-hydroxy-3H-phenoxazin-3-one 10-oxide) for assessing fungal spore viability, using the ascomycete Leptosphaeria maculans (causing blackleg disease on canola) as a ‘model pathogen’.

To examine HSVd variation in a single tree, we sequenced 70 HSVd genomes from unique apricot and plum trees and identified 11 HSVd variants. In addition, we analysed all known 572 HSVd sequences and identified 382 non-redundant HSVd variants. Ph ...

Abstract:
... By transversely cutting infected avocado plant stems and using PCR techniques on avocado leaves, two experiments were carried out to determine whether Rosellinia necatrix can invade avocado vascular tissues. We were unable to detect the pathogen in either stems or leaves in either experiment, so we concluded that R. necatrix does not invade the vascular system of the plant. Additionally, the toxin ...
