REACTION OF BARLEY GENOTYPES TO Bipolaris sorokiniana
A study on response of 29 barley genotypes resistant to Bipolaris leaf blight (Bipolaris sorokiniana) was conducted to investigate the relationship of the components of resistance of 29 barley genotypes. Data on five components of resistance viz., infection frequency (number of lesions per plant), lesion size (mm), percent leaf area affected by lesion, percent necrotic area on leaf, and disease...
متن کاملThe use of RAPD to characterize Bipolaris sorokiniana isolates.
Bipolaris sorokiniana is a phytopathogenic fungus causing diseases of cereal crops such as common root rot, the leaf spot disease, seedling blight, and black point of the grain. Random-amplified polymorphic DNA (RAPD) assay was used to investigate the genetic diversity of 20 isolates collected from different cultivars in wheat-producing regions in Brazil. Seventy primers, with random nucleotide...
متن کاملPhytotoxic sesterterpene, 11-epiterpestacin, from Bipolaris sorokiniana NSDR-011.
The structure of siccanol, a phytotoxic sesterterpene of fungal origin, was analyzed after chemical conversion by NMR spectroscopy. Siccanol was found to be an epimer of terpestacin that has been isolated from Arthrinium sp., and was thus renamed 11-epiterpestacin. Its stereochemistry was also identical with that of fusaproliferin, a structurally related mycotoxin from Fusarium proliferatum. Th...
متن کاملChromosome-based molecular characterization of pathogenic and non-pathogenic wheat isolates of Pyrenophora tritici-repentis.
The ToxA gene of Pyrenophora tritici-repentis encodes a host-selective toxin (Ptr ToxA) that has been shown to confer pathogenicity when used to transform a non-pathogenic wheat isolate. Major karyotype polymorphisms between pathogenic and non-pathogenic strains, and to a lesser extent among pathogenic strains, and among non-pathogenic strains were identified. ToxA was localized to a 3.0 Mb chr...
