Citrus canker caused by Xanthomonas citri subsp. citri (Xcc) is one of the most important bacterial diseases of citrus. Because citrus canker is not found in many countries including European Union and Australia, Xcc is strictly regulated in order to prevent its spread. In this study, the effects of X-irradiation on Xcc growth either in the suspension or on the surface of citrus fruits were inv...

Citrus Huanglongbing (HLB) associated with 'Candidatus Liberibacter asiaticus' (Las) and citrus canker disease incited by Xanthomonas citri are the most devastating citrus diseases worldwide. To control citrus HLB and canker disease, we previously screened over forty antimicrobial peptides (AMPs) in vitro for their potential application in genetic engineering. D2A21 was one of the most active A...

Increasing international travel and trade have rendered U.S. borders much more porous and dramatically increased the risk of introductions of invasive plant pests into agricultural crops (1). Nationally, the responsibility for safeguarding agriculture falls to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine (USDA, APHIS, PPQ). Howe...

Citrus canker disease caused by Xanthomonas citri subsp. 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 sinensis Osbeck) plants were produced via constitutively overexpressing a spermidine synthase. To unravel the molecular mechanisms underlying Xcc resistance of the transge...

The objectives of the current study were to isolate and identify the pathogen responsible for citrus canker and investigate the efficacy of sulfone derivatives containing 1,3,4-oxadiazole moiety on controlling citrus canker caused by Xanthomonas citri subsp. citri (Xcc) under in vitro and field conditions. In an in vitro study, we tested eight sulfone derivatives against Xcc and the results dem...

Citrus is a highly valued tree crop worldwide, while, at the same time, citrus production faces many biotic challenges, including bacterial canker and Huanglongbing (HLB). Breeding for disease-resistant varieties is the most efficient and sustainable approach to control plant diseases. Traditional breeding of citrus varieties is challenging due to multiple limitations, including polyploidy, pol...

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...

asiatic citrus canker is a devastating disease resulting in drastic economic losses in citriculture worldwide. amongst three different types of the disease, i.e. a, a* and aw, the a* type is genetically less known. in order to comprehend the behavior of the asiatic citrus canker a*-type strain (xanthomonas citri subsp. citri) in the vicinity of the host cells, a targeted semi-quantitative trans...

ABSTRACT Citrus bacterial canker disease has been introduced at least three times into Florida in the last 15 years and, despite federal and state quarantine and eradication efforts, continues to spread in Florida. Accurate, fast, and reliable detection of the causal agent is of great importance. However, citrus bacterial canker is caused by at least two groups of phylogenetically distinct Xant...

Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), is one of the most destructive diseases of citrus. Progress of breeding citrus canker-resistant varieties is modest due to limited resistant germplasm resources and lack of candidate genes for genetic manipulation. The objective of this study is to establish a novel heterologous pathosystem between Xcc and the well-established model...
