The importance of the citrus crops is recognized throughout world. Despite tremendous advancements in agricultural technology, fruit production still considered a significant challenge. Various biotic factors have trampled down rate Citrus many places. Among them, canker caused by Xanthomonas axonopodis pv. citri (Xac) and (Xcc) great importance. Infection Xac leads to lesion development leaves...

bacterial canker of stone fruit trees caused by pseudomonas syringae pv. syringae has become widespread throughout most fruit growing areas of iran (abbasi et al 2013). to evaluate the diversity of the strains and possible species inciting the disease in the central areas of the country, surveys were made in 2014 and 2015 in some central provinces including charmahal-and-bakhtiary, isfahan, qum...

A bacterial pathogen, Pseudomonas syringae pv. actinidiae (Psa), is a causal agent of kiwifruit bacterial canker worldwide. Psa biovar 3 (Psa3) was first detected in 2011 at an orchard in Dodeok-myeon, Goheunggun, Jeonnam Province in Korea. In this study, we present the results of an epidemiological study regarding Psa3 occurrence on kiwifruit orchards in Korea for the period of 2013 to 2015. S...

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 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...

Xanthomonas citri pv. citri is a clonal group of strains that causes citrus canker disease and appears to have originated in Asia. A phylogenetically distinct clonal group that causes identical disease symptoms on susceptible citrus, X. citri pv. aurantifolii, arose more recently in South America. Genomes of X. citri pv. aurantifolii strains carry two DNA fragments that hybridize to pthA, an X....
