Última Morphological characterization and genetic analysis of Drechslera teres isolates Genet. Mol. Biol. Frazzon,A.P.G.; Matsumura,A.T.S.; Van Der Sand,S.T.. Net blotch, caused by the phytopathogen Drechslera teres, is a common disease of barley (Hordeum vulgare L) and is responsible for large economic losses in some barley growing areas. In this study the morphology and genetic variability of eight D. teres isolates from different regions of the Brazilian state of Rio Grande do Sul were investigated. Colony morphology was studied on potato-dextrose-agar (PDA) and genetic variability investigated using the random amplified polymorphic-DNA (RAPD) technique. 27 commercially available primers were tested of which 16 were selected for use in polymorphic analysis due to their good resolution and reproducibility. Similarity coefficients were used to construct dendrograms based on colony morphology and RAPD data...

E; Sisterna,Marina N. "Net blotch" (Drechslera teres) and "Bipolaris spot blotch" (Bipolaris sorokiniana) are foliar diseases of barley. Biological control is currently considered as an efficient alternative to chemical management of these plant diseases. The aim of the present study was to identify 2 isolates of Chaetomium (C2 and C5), endophytics on barley seedlings and to study the in vitro interactions with D. teres and B. sorokiniana, isolated from seeds of the same host. Cultural and morphological characterization of all microorganisms was done. In addition, molecular characterization of Chaetomium spp. was conducted and dual culture tests were carried out to find, by microscopic observations, the effects of the antagonist on the morphology of the pathogens. The results... Tipo: Info:eu-repo/semantics/article Palavras-chave: Bipolaris sorokiniana; Chaetomium globosum; Drechslera teres; Antibiosis; Endophyte; Mycoparasitism.
