Ten microsatellite markers were developed for the fungus Kirramyces gauchensis, which causes an important stem canker disease of Eucalyptus trees in plantations. Primers for 21 microsatellite regions were designed from cloned fragments. Fourteen of the primer pairs provided single amplicons and 10 of these were polymorphic for K. gauchensis. Allelic diversity ranged from 0.21 to 0.76 with a tot...
Digital image processing is employed in numerous areas of biology to identify and analyse problems. This approach aims to use image processing techniques for citrus canker disease detection through leaf inspection. Citrus canker is a severe bacterium-based citrus plant disease. The symptoms of citrus canker disease typically occur in the leaves, branches, fruits and thorns. The leaf images show...
Studies on some bacterial diseases of fruit plants from Aurangabad district was carried out during 2003-2009. They are: Leaf necrosis of Custard apple caused by Xanthomonas annonae; Citrus canker caused by Xanthomonas campestris pv. citri; Bacterial canker of Mango caused by Xanthomonas campestris pv. mangiferaeindicae; Leaf necrosis of Guava caused by Xanthomonas psidae; and leaf spot of Badam...
Abstract Blackleg (stem canker) of crucifers is a globally important disease caused by multiple genetic subclades the fungi Plenodomus lingam (syn.: Leptosphaeria maculans ) and biglobosus biglobosa ). In our study, we monitored geographical distribution these two pathogen species from rapeseed growing areas in Hungary. Multiplex PCR identified 48.7% isolates as , which indicates non-recent int...
A survey of 67 commercial fields in 19 locations was conducted the southern Pampean region Argentina for Phomopsis stem canker sunflower (Helianthus annuus L.) between 2014 and 2019. total 210 plants having typical symptoms were randomly sampled, fungal isolation performed. Of 187 isolates Diaporthe that recovered, 94% showed morphological characteristics similar to D. helianthi, 3% gulyae, 1% ...
Of all the agricultural pests and diseases that threaten citrus crops, citrus canker is one of the most devastating. The disease, caused by the bacterium Xanthomonas axonopodis pv. citri, occurs in large areas of the world's citrus growing countries including India. At least 3 distinct forms or types of citrus canker are recognized. Among these, Asiatic form (Canker A) is the most destructive a...
Citrus canker is a very destructive disease of citrus species. The challenge is to find new compounds that show strong antibiotic activity and low toxicity to plants and the environment. The objectives of the present study were (1) to extract, purify and evaluate the secondary metabolites with antibiotic activity produced by Pseudomonas aeruginosa LV strain in vitro against Xanthomonas citri su...
