Research ArticleOpen accessEvery word in the titleMolecular Characterization of Vaccine-Derived Mutants of Avian Metapneumoviruses Isolated from Turkeys in EgyptAbdel-Satar Arafa, Wessam Mady, Ahmed Hussein et al.Avian metapneumovirus (aMPV) causes acute respiratory infection in turkeys with sudden onset and rapid spread in the infected flocks. Vaccinated flocks frequently showed clinical signs typical like the non-vaccinated flocks in Egypt, this situation suggests a virulent vaccine virus was circulating in the field. Oropharyngeal and nasal sinus swabs were collected from 100 turkeys from 10 commercial farms with mild … …Current Research in Virology, Vol. 4, Issue 1 · 12 Aug 2015 · 12,748 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleDetection of Hepatitis C Virus Resistant Mutants in the era of Direct Acting AntiviralsLivia Maria Gonçalves Rossi, Paula RahalHepatitis C Virus (HCV) infects millions of people and represents an important public health problem in different regions of the world. Drug resistance is a major challenge for HCV-infection related control. Importantly, the arrival of a plethora of novel, more powerful drugs has revolutionized the field of HCV treatment. Here, we discuss the relevance of identification of HCV resistant mutants … …American Journal of Infectious Diseases, Vol. 10, Issue 4 · 7 Jan 2015 · 6,429 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEthanol Production by Novel Proline Accumulating Pichia kudriavzevii Mutants Strains Tolerant to High Temperature and Ethanol StressesRika Indri Astuti, Sena Alifianti, Ratu Nabila Maisyitoh et al.Accumulation of osmoprotectant molecule, proline, has been reported to induce a stress tolerance phenotype in yeast cells. In this study, two ethanologenic isolates of yeast, Pichia kudriavzevii (R and T), both capable of using both five and six sugar compounds to produce ethanol, were mutated via ethyl methanesulfonate (EMS) treatment. Prolineaccumulating mutant strains were selected by using proline-analogue (L-azetidine-2-carboxylic acid). … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 11 Sep 2018 · 7,838 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsInfluence of Drought Stress on Growth and Yield of Soybean (Glycine max L.) Genotypes in Northern GhanaIsaac Kwahene Addai, Alhassan Bawa, Maganoba CharlesStudies on induced mutation were conducted and the results indicated that stable, but desirable soybean mutant genotypes with improved agronomic traits have been produced. A series of evaluations of these mutant genotypes had earlier on been carried out and high-yielding ones such as 150, 200, 250, and 300 Gy have been identified. In the present study, the above genotypes were … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 1 Jun 2023 · 6,777 accessesView PDF Cite

InvestigationOpen accessIn the keywordsA State of PSI and PSII Photochemistry of Sunflower Yellow-Green Plastome MutantMaksim S. Makarenko, Nikolay V. Kozel, Alexander V. Usatov et al.Chlorophyll deficient mutants are appropriate model objects for a large number of investigations in the field of photosynthesis. In this study, we identified a state of Photosystem I (PSI) and Photosystem II (PSII) photochemistry and light responses of the sunflower yellow-green mutant line - en:chlorina-7, wherein mutations in chloroplast genes have been previously localized. The conducted research revealed low content … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 29 Dec 2016 · 7,458 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Tool for Generation and Minimization of Test Suite by Mutant Gene AlgorithmSelvakumar Subramanian, Ramaraj NatarajanProblem statement: This study proposes a new idea for generation of minimized test suite in the test case generation using the mutant gene algorithm, which not only identifies the best test cases but also reduces the number of test cases generated, selects test cases optimally there improving the performance in testing of software. Test cases are generated by using branch … …Journal of Computer Science, Vol. 7, Issue 10 · 9 Aug 2011 · 7,164 accessesView PDF Cite
