Host Range of Streptomycete Strains Causing Common Scab

Diversity of Streptomyces strains causing potato scab disease in Hamedan province and their thaxtomin production potential

Hamedan province is one of the main potato growing areas in Iran. Potaoto scab disease caused by Streptomyces spp. is one of the prevalent and important diseases of potato in this provice. Potato tubers with symptoms of scab diseases including raised and deep or shallow pitted lesion were collected from potato growing area in this region. A total of 20 and 25 strains of Streptomyces were isolat...

A survey of genetic variation in streptomyces isolates causing potato common scab in the United States.

ABSTRACT Common scab is a serious disease of potatoes and other root and tuber crops, affecting crop quality and market value. The disease is caused by gram positive soil bacteria in the genus Streptomyces. Disease incidence and severity vary in different locations and years; this is due in part to variation in the environment (weather) and genetic variation in potato cultivars. Little informat...

CHARACTERIZATION OF Colletotrichum spp. STRAINS FROM COMMON BEAN ANTHRACNOSE AND SCAB LESIONS

Antibacterial potential of streptomycete strains from Antarctic soils

The exploration of habitats with unusual environment and poorly explored areas such as Antarctica is one of the strategies for discovery of new biologically active substances and/or new producers. The aim of this study was to identify the actinomycetes isolated from the soils of the island Livingston - Antarctica and to investigate their potential to synthesize antibacterial agents against phyt...

Optimization of streptomycete strains producing polyether and macrolide antibiotics.

screened for high-frequency transfer of OTC resistance. Although such strains were found at quite a high frequency (about 1 in IOOO), it was subsequently discovered that a second plasmid SRP2 had actually been primed. This possessed much weaker sex-factor activity than SRPl . Neither plasmid has proved amenable to physical isolation or analysis, and with the advent of recombinant DNA techniques...
