The 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 کاملREACTION 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 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 کاملMolecular characterization of Chaetomium species using URP-PCR
Chaetomium spp. are common colonizers of soil and cellulose-containing substrates. Seventeen isolates of Chaetomium spp., which included 15 isolates of C. globosum and one each of C. reflexum and C. perlucidum, were genetically characterized with universal rice primers (URP primers derived from DNA repeat sequences in the rice genome) using polymerase chain reaction (URP-PCR). Out of the 12 URP...
متن کاملEvaluation of Pathogenic Variability Based on Leaf Blotch Disease Development Components of Bipolaris sorokiniana in Triticum aestivum and Agroclimatic Origin
Leaf blotch of wheat caused by Bipolaris sorokiniana is a major constraint to wheat production, causing significant yield reduction resulting in severe economic impact. The present study characterizes to determine and compare pathogenic variability exist/not based on components of leaf blotch disease development and level of aggressiveness due to agroclimatic condition of B. sorokiniana in whea...
