“…S. stelliscabiei has been reported from France and the USA (Bouchek-Mechiche et al 2000;Wanner 2006). Phylogenetically more distant CS-causing species are known from multiple regions, including S. turgidiscabies in Japan and Finland (Kreuze et al 1999;Miyajima et al 1998), and S. acidiscabies from Maine, Korea and Japan (Lambert and Loria 1989a;Song et al 2004;Tóth et al 2001). Unique species have been described from Korea (Park et al 2003a, b).…”

To determine distribution and prevalence of Streptomyces species associated with common scab in North America, more than 1,400 isolates were made from scabby potato tubers. Samples were obtained from locations across the continent, and from multiple sites in close geographic proximity. Most potentially pathogenic isolates belonged to four species previously associated with common scab, S. scabies, S. europaeiscabiei, S. stelliscabiei, and S. sp. IdahoX. Additionally, small numbers of potentially pathogenic isolates were identified as S. acidiscabies, S. turgidiscabies and six additional ribotypes. S. europaeiscabiei was most common in the west and S. scabies predominated in the middle and eastern Midwest. Beyond this geographic trend, species distribution was patchy. A single species often predominated in a field while neighboring fields had different species. Local and regional variation was seen when isolates were genotyped for repetitive sequence element patterns, reflecting the conserved or core genome, and genes characteristic of the Streptomyces pathogenicity island, reflecting flexible components of the Streptomyces genome. This is the largest survey to date of the distribution of common scab-causing species, and will be a resource for population biology studies and for tracing the evolutionary history and spread of common scabassociated Streptomyces.Resumen Para determinar la distribución y prevalencia de especies de Streptomyces asociadas con la sarna común en Norteamérica, se hicieron más de 1,400 aislamientos de tubérculos de papa con sarna. Las muestras fueron obtenidas de localidades de todo el continente y de múltiples lugares geográficamente próximos. Los aislamientos potencialmente más patogénicos fueron de cuatro especies previamente asociadas con sarna común, S. scabies, S. europaeiscabiei, S. stellicabiei y S. sp. IdahoX. Adicionalmente, un número pequeño de aislamientos potencialmente patogénicos fueron identificados como S. acidiscabies, S. turgidiscabies y seis ribotipos adicionales. S. europaeiscabiei fue el más común en el oeste y S. scabies predominó en el centro y este del Medio Oeste. Más allá de esta tendencia geográfica, la distribución de especies fue en parches. Una sola especie a menudo predominó en un campo mientras en los campos vecinos se encontraron diferentes especies. Se vieron variaciones locales y regionales cuando a los aislamientos se les determinó el genotipo para patrones de elementos con secuencias repetitivas que reflejan el genoma conservado o central, y genes característicos de la isla de patogenicidad de Streptomyces, reflejando componentes flexibles del genoma de Streptomyces. Este es la pesquisa más extensa a la fecha sobre la distribución de las especies que causan sarna común, y será un recurso para estudios de biología poblacional y para determinar la historia evolutiva y diseminación de Streptomyces asociado a la sarna común.Keywords Streptomyces scabies .

“…Streptomyces scabiei ) was first described in 1891 and has a global distribution (Lambert and Loria, 1989a). During the last 75 years, two additional species, Streptomyces acidiscabies (Lambert and Loria, 1989b) and Streptomyces turgidiscabies (Miyajima et al ., 1998), have independently emerged as pathogens in the USA and Japan respectively. The emergence of new phytopathogenic species has led us to postulate that the genetic determinants for plant pathogenesis are being shared between Streptomyces species that are adapted to specific ecological niches.…”

SummaryPotato scab is a globally important disease caused by polyphyletic plant pathogenic Streptomyces species. Streptomyces acidiscabies , Streptomyces scabies and Streptomyces turgidiscabies possess a conserved biosynthetic pathway for the nitrated dipeptide phytotoxin thaxtomin. These pathogens also possess the nec1 gene which encodes a necrogenic protein that is an independent virulence factor. In this article we describe a large (325-660 kb) pathogenicity island (PAI) conserved among these three plant pathogenic Streptomyces species. A partial DNA sequence of this PAI revealed the thaxtomin biosynthetic pathway, nec1 , a putative tomatinase gene, and many mobile genetic elements. In addition, the PAI from S. turgidiscabies contains a plant fasciation ( fas ) operon homologous to and colinear with the fas operon in the plant pathogen Rhodococcus fascians . The PAI was mobilized during mating from S. turgidiscabies to the nonpathogens Streptomyces coelicolor and Streptomyces diastatochromogenes on a 660 kb DNA element and integrated site-specifically into a putative integral membrane lipid kinase. Acquisition of the PAI conferred a pathogenic phenotype on S. diastatochromogenes but not on S. coelicolor . This PAI is the first to be described in a Gram-positive plant pathogenic bacterium and is responsible for the emergence of new plant pathogenic Streptomyces species in agricultural systems.
