In recent years, use of the DNA-intercalating dye propidium monoazide (PMA) in real-time PCR has been reported as a novel method to detect viable bacteria in different types of samples, such as food, environmental, and microbiological samples. In this study, viable cells of Acidovorax citrulli, the causal agent of bacterial seedling blight and fruit blotch, were selectively detected and differe...

rhizoxin was achieved by enzymatic approach. Characteristic features of the present synthesis are (1) enantioselective hydrolysis of prochiral P-substituted glutarates with pig liver estemse, and (2) stereoselective cyclichydroboration of the 1,5-diene 8. Enantioand stereoselective synthesis of the right-half segment (1, Cl-Cg) of macrolide antibiotic Rhizoxin is an antitumor antibiotic isolate...

Phytophthora pathogens are responsible for some of the most serious diseases of cocoa including phytophthora pod rot (PPR) or black pod, stem canker, leaf and seedling blight, chupon wilt and flower cushion infections. PPR causes 10–30% annual losses in production of cocoa beans globally, and much higher losses locally in particularly wet and humid conditions. Stem canker causes further losses ...

Diseases caused by Alternaria sp. are among the most common diseases of crops throughout the world. Alternaria sp. is a common component of the flora of wheat seed. Although isolation of Alternaria sp. from wheat (Triticum aestivum) seed has been reported in Argentina, development of the Alternaria blight in plants from infected seeds has not been demonstrated experimentally. Seed transmission ...

during winter 2004 and 2005, two field and glasshouse experiments were conducted to evaluate the response of 471 chickpea genotypes to ascochyta rabiei, as ascochyta blight (ab) disease in chickpea (cicer aurietimum). frequent rainfall at flowering and pod formation stages made favorite conditions conducive for the infection and symptoms expression. so, the genotypes with high level of toleranc...

Torrey Bot. Club 115: 32-44. 1988.-American chestnut sprout populations were mapped on 14 sites of approximately 1 square kilometer in Connecticut and Massachusetts. Living sprouts were nearly continuous in ...

ABSTRACT Alsen is a recently released spring wheat cultivar that has been widely grown in the United States because it has resistance to Fusarium head blight and leaf rust caused by Puccinia triticina. Norm is a high yielding wheat cultivar that has been very resistant to leaf rust since it was released. Alsen and Norm were genetically examined to determine the number and identity of the leaf r...
