Abstract:

Interest in the interaction between the citrus leafminer (Phyllocnistis citrella) and citrus bacterial canker, caused by Xanthomonas axonopodis pv. citri, has increased as a greater incidence and severity of canker-diseased plants was observed in groves infested with the citrus leafminer. To determine whether adults of the citrus leafminer could act as vectors of citrus canker, we investigated two potential mechanisms for direct spread by leafminer adults using experimental microcosms. First, adult leafminers were raised on canker-infected foliage and were allowed to mate and lay eggs on healt

Abstract:

Citrus canker presents major challenges in citrus production worldwide. The disease spreads and develops rapidly under conducive environmental conditions, and Louisiana’s hot and humid weather provides highly favorable conditions for citrus canker development in both commercial and backyard citrus production. Despite being considered eradicated in late 1940s, citrus canker was reconfirmed in Louisiana in 2013. Citrus is the most popular fruit tree grown commercially and in backyards in Louisiana, and satsumas dominate with 63% of total citrus acreage. The results from an annual citrus cooperat

Abstract:

Climatic conditions play a significant role in the development of citrus canker caused by Xanthomonas citri pv. citri (Xcc). Citrus canker is regarded as one of the major threats being faced by citrus industry in citrus growing countries of the world. Climatic factors exert significant impacts on growth stage, host susceptibility, succulence, vigor, survival, multiplication rate, pathogen dispersion, spore penetration rate, and spore germination. Predicting the impacts of climatic factors on these traits could aid in the development of effective management strategies against the disease. This

Geospatially referenced citrus canker infection data from infections that were discovered after the 2004 hurricanes were examined in relation to wind and rain conditions experienced during the hurricanes and used to develop a predictive model to explain storm-related spread of citrus canker.

Abstract:

Citrus greening disease (HLB) and citrus canker cause financial losses in Florida citrus groves via smaller fruits, blemishes, premature fruit drop, and/or eventual tree death. Management of these two diseases requires early detection and distinction from other leaf defects and infections. Automated leaf inspection with hyperspectral imagery (HSI) is tested in this study. Citrus leaves bearing visible symptoms of HLB, canker, scab, melanose, greasy spot, zinc deficiency, and a control class were collected, and images were taken with a line-scan HSI camera. YOLOv8 was trained to classify multis

Abstract:

Citrus canker, caused by the bacterium Xanthomonas axonopodis pv. citri, is one of the most devastating diseases hampering worldwide citrus production, including in Nepal. Citrus canker is a significant threat to all citrus-growing regions because of its rapid spread, high potential for damage, and impact on export sales and domestic trade. The study was to solve the major problem associated with citrus canker by identifying and evaluating the in vitro efficacy of different chemicals available in the local market. The pathogen was isolated from the diseased plants, and a pure culture was obtai

Abstract:

The ability to swiftly respond to pathogen incursions relies heavily on fast and accurate diagnostics. Current published assays for citrus bacterial canker do not target Xanthomonas citri pv. citri, the causative agent, with high specificity when testing Australian samples. While the current diagnostics are useful in countries where canker is endemic, the detection of canker in Australia requires an emergency response. Close relatives to X. citri pv. citri found in Australia may generate false positives with the current recommended diagnostic assays. Therefore, we developed a more specific det

Citrus canker disease caused byXanthomonas citrisubsp.citri(Xcc) is one of the most devastating diseases affecting the citrus industry worldwide. In our previous study, the canker-resistant transgenic sweet orange (Citrus sinensisOsbeck) plants were producedviaconstitutively overexpressing a spermidine synthase. To unravel the molecular mechanisms underlying Xcc resistance of the transgenic plants, in the present study global transcriptional profiling was compared between untransformed line (WT) and the transgenic line (TG9) by hybridizing with Affymetrix Citrus GeneChip.

Abstract:

Xanthomonas citri subsp. citri, a causative agent of the citrus canker (CC) disease, belongs to one of the essential groups of the bacterial phytopathogen family, Xanthomonadaceae. It has been a potential threat to the globally significant citrus fruit crop, which has remained under investigation for disease management and epidemiology since the 1980s. In Pakistan, the average yield of citrus is 11 t/ha, which is lower than other countries, including China, Brazil, and India, having average productions of 27, 26, and 22 tons/hectare, respectively. Citrus canker is one of the most devastating d

Abstract:

Asiatic citrus canker, caused by Xanthomonas citri pv. citri, is a bacterial disease of major economic importance in tropical and subtropical citrus-producing areas. X. citri pv. citri pathotype A can cause severe infection in a wide range of citrus species and induces erumpent, callus-like lesions with water-soaked margins evolving to corky cankers and leading to premature fruit and leaf drop and twig dieback on susceptible/very susceptible cultivars. A chlorotic halo is typically visible around canker lesions on leaves and young fruit, but not on mature fruit and twigs. This quarantine organ

Citrus is a significant crop playing an important role in Pakistan’s economy. However, its production is under constant threat by numerous pathogens resulting in considerable economic losses. Bacterial canker caused by Xanthomonas axonopodis pv. citri is a major limiting factor in the successful production of citrus. Isolates of the pathogen were collected from infected citrus orchard of Bahawalpur region. Bacterial pathogen was characterized by morphological evaluation, pathogenicity and biochemical tests including gram staining, catalase test, KOH test, simmons citerate test, starch hy

Abstract:

Bacteriophages, alone or in combination with copper bactericides, were evaluated for managing Asiatic citrus canker and citrus bacterial spot incited by Xanthomonas axonopodis pathovars citri and citrumelo, respectively. In a set of five greenhouse experiments, phage treatment provided consistent control of citrus canker, causing an average of 59% reduction in disease severity. However, treatment with phage was ineffective if applied with skim milk, a protective formulation, which increases phage residual activity. In nursery settings, phage treatment also reduced disease but was less effectiv

Citrus (family Rutaceae) stands as a prominent fruit crop on a global scale, bearing substantial significance. Renowned for its abundance of fiber, amino acids, antioxidants, vitamin C, and carbohydrates. However, the successful production of citrus is persistently challenged by the menacing presence of citrus canker caused by Xanthomonas citri subsp. citri (Xcc), posing 5-30% yield losses in Pakistan.
