Physical Changes in Satsuma Mandarin Leaf after Infection of Elsinoë fawcettii Causing Citrus Scab Disease.
Citrus scab disease is one of the destructive diseases that reduce the value of fruit for the fresh market. We analyzed the process of symptom development after infection with scab pathogen Elsinoë fawcettii in the susceptible satsuma mandarin leaves to observe the structural modification against pathogen. The cuticle and epidermal cells along with 3-5 layers of mesophyll tissue were degraded 1...
متن کاملPhylogeny and taxonomy of the scab and spot anthracnose fungus Elsinoë (Myriangiales, Dothideomycetes)
Species of Elsinoë are phytopathogens causing scab and spot anthracnose on many plants, including some economically important crops such as avocado, citrus, grapevines, and ornamentals such as poinsettias, field crops and woody hosts. Disease symptoms are often easily recognisable, and referred to as signature-bearing diseases, for the cork-like appearance of older infected tissues with scab-li...
متن کاملFactors Affecting the Production of Elsinochrome Phytotoxin by the Citrus Scab Pathogen, Elsinoë fawcettii
Elsinochrome (ESC), light-activated, nonhost-selective phytotoxin, is produced by many members of the genus Elsinoë and required for full virulence of the fungus. It appears that approaches disrupting the ESC production will likely reduce disease severity caused by Elsinoë pathogens. In this study, the influence of nutritional and environmental factors on ESC biosynthesis by the citrus scab pat...
متن کاملResistance to Elsinoë Ampelina and Expression of Related Resistant Genes in Vitis Rotundifolia Michx. Grapes
Muscadine grapes (Vitis rotundifolia Michx) are considered as excellent genetic resources for grape breeding programs as they are known for their hardiness and resistance to pests and diseases. However, contrary to popular belief, our study indicated that not all muscadine cultivars are resistant to anthracnose disease. In order to identify a source of genetic tolerance towards anthracnose amon...
متن کاملControl of the sheep scab mite Psoroptes ovis in vivo and in vitro using fungal pathogens.
As part of a research programme designed to identify biological agents for the control of sheep scab, the pathogenicity of the fungus Metarhizium anisopliae to Psoroptes mites in the presence of sheepskin and wool was examined in the laboratory. No inhibitory effects of skin and wool were observed and high levels of infection were recorded. Subsequently the pathogenicity of formulations of both...
