Abstract:
... Guignardia citricarpa Kiely (anamorph Phyllosticta citricarpa Van der Aa), the causal agent of citrus black spot disease, is subject to phytosanitary restrictions in the EU and USA, such that consignments of citrus are rejected at import if citrus black spot is identified on inspection. Due to the variability of black spot symptoms, positive identification solely on the basis of visual inspection ...

Abstract:
... The Fusarium genus causes devastating plant diseases worldwide, in which Fusarium oxysporum is the most serious crop pathogen. Disease monitoring is the basis of integrated pest management of any disease. The lack of rapid, accurate, and reliable device to detect and identify plant pathogens is one of the main limitations in integrated disease management. This study describes an efficient and quan ...

Abstract:
... Recent taxonomic advances, based on biochemical and genotypic processes demonstrate that the plant pathogenic species Pseudomonas cichorii consists of a cluster of closely related genomic groups. Prior to this study, three morphotype groups had been described (C1-C3), all sharing various phenotypic and biochemical characters but partially differing in their DNA content. All entities of the complex ...

Abstract:
... Guggal (Commiphora wightii (Arnott) Bhandari comb. nov.) is a small tree which is tapped for medicinally important oleo–gum–resin. Naturally infected plant oozes oleo–gum–resin from its trunk and primary branches. However, in either case, the plant dies slowly after oozing. A bacterium was established to be responsible for these phenomena. Four isolates of this bacterium were characterised by bioc ...

Abstract:
... Rice brown spot (BS) is a chronic disease that affects millions of hectares of rice every growing season, grown by some of the most resource-poor farmers. Despite its widespread occurrence and impact, much still needs to be understood about BS. Reported yield losses in relative terms vary widely from 4 to 52 %. However, accurate, systematic estimates are lacking. BS is conventionally perceived as ...

Abstract:
... Melampsora medusae is a quarantine fungus in the European Union (EU) that causes a damaging leaf rust disease on poplars. Two formae speciales of the pathogen can be distinguished, M. medusae f. sp. deltoidae and M. medusae f. sp. tremuloidae, but the EU plant health directive 2000/29/EC currently in force does not make the distinction between them. EU countries must have the ability to detect and ...

The plant β-1,3-glucanases are considered to have a broad range of biological functions in the normal physiological process as well as in the defence response against pathogens. Some plant β-1,3-glucana ...

Whatever the MDR phenotype, resistance was recorded to anilinopyrimidines, diethofencarb, iprodione, fludioxonil, tolnaftate and several respiratory inhibitors (e.g., penthiopyrad, pyraclostrobin). In MDR1 strai ...

We produced attenuated mutants of Potato virus Y necrotic strain not only by nitrous acid treatment but also by a novel method, probably unique to plant viruses, which we call the “mutagenesis-in-tissue culture method”. This relies on the natural or experimental generation of virus sequence variants within an infected plant, and then isolating the mutants by serially cloning them in plants. A tota ...
