The RpfCG two-component system negatively regulates the colonization of sugar cane stalks by Xanthomonas albilineans.
The genome of Xanthomonas albilineans, the causal agent of sugar cane leaf scald, carries a gene cluster encoding a predicted quorum sensing system that is highly related to the diffusible signalling factor (DSF) systems of the plant pathogens Xylella fastidiosa and Xanthomonas campestris. In these latter pathogens, a cluster of regulation of pathogenicity factors (rpf) genes encodes the DSF sy...
متن کاملEpidemiology of Leaf Scald in the Moreton District of Queensland
The incidence and geographic distribution of leaf scald (Xanthomonas albilineans (Ashby) Dowson) in the Moreton district between 1951 and 1975 is described. Most of the infection has been in 471. Increase in incidence of the disease appears to be favoured by periods of high rainfall followed by dry weather. A survey was made, at monthly intervals from January to June 1975, to try to determine l...
متن کاملLeaf Temperatures of Sugar Cane.
Since the results in the literature are at considerable variance regarding leaf temperatures with reference to the surrounding air temperature, the writer thought it would be of interest to check some leaf temperatures in a different section of the country from those previously reported. The investigations of CURTIS (2) were performed at Berkeley and Riverside, California, and those of CLUM (1)...
متن کاملGlycoproteins of sugarcane plants facilitate the infectivity of Ustilago scitaminea and Xanthomonas albilineans, two sugar- cane pathogens
Sugarcane plants produce heterofructans composed of homofructan domains consisting of β-1,2-fructofuranoside chains which intercalate variable-length segments of polygalactitol. Sometimes, these heterofructans appear as the glycosidic moiety of glycoproteins. They are produced as a response to mechanical injuries and pathogen infections. These glycoproteins act as a defense mechanism against sm...
متن کاملGenetic Diversity and Phylogenetic Study of Xanthomonas arboricola pv. juglandis the Causal Agent of Walnut Bacterial Blight Disease
Bacterial blight (Xanthomonas arboricola pv.juglandis) is one of the main diseases of walnut that reduce the yield in the central, western and northern regions of Iran. This disease was first reported form, Qazvin and Mazandaran, then widely reported from northern, central and western provinces. To identify the cause of the disease in different provinces, infected leaves collected from Alborze,...
