25. Alterations in Biomarkers Associated with Sterility in Pectinophora gossypiella (Saunders) Induced by Gamma Irradiation
ABSTRACT Nowadays, radiation technology is widely used to produce changes in Biosystems. The goal of this work is to determine the variation induced male Pectinophora gossypiella in gamma-irradiated as pupae using 50Gy and 150Gy. Comparing elements composition and DNA (using RAPD-PCR) between substerile 50Gy and the sterile dose 150Gy in P. gossypiella showe

26. Virulência, resistência e relação genética de Escherichia coli e Klebsiella sp.isoladas de potros de muar
RESUMO Doenças respiratórias são comuns em potros de equinos, porém pouco se sabe sobre tais infecções em potros de muar. Este estudo buscou caracterizar Escherichia coli e Klebsiella sp. isolados de lavados traqueais (TW) e amostras fecais (FS) de potros de muar com e sem evidências citológicas de doença respiratória. As amostras bacterianas foram

28. Virulence factors and genetic variability of vaginal Candida albicans isolates from HIV-infected women in the post-highly active antiretroviral era
ABSTRACT Vulvovaginal candidiasis (VVC) in HIV-infected (HIV+) women is a serious public health problem. However, little is known about the virulence mechanisms of vaginal Candida albicans from HIV+ women in the post-highly active antiretroviral therapy (HAART) era. Here, we report a comparative analysis of the expression of key virulence factors and genetic

29. Genetic diversity and population densities of endophytic Bacillus spp. in yam plants
ABSTRACT This study was conducted as a first step in exploiting endophytic bacteria to improve yam production. Little information is available on population densities and genetic diversity of endophytic bacteria in yam cultivated in tropical regions. This study demonstrated that higher densities of total endophytic bacteria and Bacillus occur in the interior

30. Functional Genes of Microorganisms, Comprehending the Dynamics of Agricultural Ecosystems
ABSTRACT The microbial composition of different types,in ecosystems (including agro-ecosystems), has been investigated in a rapidly growing number of studies in the past few years. The importance of microorganisms, regarding the maintenance and stability of nutrients in agroecosystems, is a key to maintain the sustainability of a crop. Molecular tools to stu

31. Genetic diversity in populations of Maytenus dasyclada (Celastraceae) in forest reserves and unprotected Araucaria forest remnants
ABSTRACT Understanding the genetic structure and diversity of plants is fundamental to their conservation and permits their sustainable use by local communities. The genus Maytenus (Celastraceae) is composed of plants possessing pharmacological and antioxidant properties. However, the genetic and economic properties of the species M. dasyclada, a typical spe

32. Determination of the mode of reproduction of bahiagrass hybrids using cytoembryological analysis and molecular markers
ABSTRACT The aim of this study was to determine the mode of reproduction of a hybrid progeny derived from intraspecific crosses of Paspalum notatum through cytoembryological analysis and use of RAPD (random amplification of polymorphic DNA) molecular markers. Cytoembryological analysis allowed identification of the mode of reproduction of 28 plants that were

33. Evaluation of Genetic Diversity amongthe Pakistani Wheat (Triticumaestivum L.) Lines through Random Molecular Markers
ABSTRACT The presence of geneticdiversity is of great importance in improving wheat traits and developing strategies for optimal conservation of germplasm. Genetic diversity was assessed among common wheat cultivars using RAPD (Random Amplified Polymorphic DNA) markers at the Center of Agriculture, Biochemistry and Biotechnology (CABB), University of Agricul

34. Assessment of Genetic Fidelity of in vitro Raised Plants in Swertia chirayita through ISSR, RAPD analysis and Peroxidase Profiling during Organogenesis
ABSTRACT An efficient in vitro regeneration protocol for medicinally important herb Swertia chirayita was developed and the genetic fidelity was assessed using RAPD and ISSR markers. The best shoot regeneration was observed on MS basal supplemented with 1.0 mg/L Benzyl amino purine (BAP) in combination with Indole-3-acetic acid (IAA) (0.5 mg/L) that resulted

35. Highly Solvent Tolerance in Serratia marcescens IBBPo15
ABSTRACT The aim of this study was to investigate the solvent tolerance mechanisms in Serratia marcescens strain IBBPo15 (KT315653). Serratia marcescens IBBPo15 exhibited remarkable solvent-tolerance, being able to survive in the presence of high concentrations (above 40%) of toxic organic solvents, such as cyclohexane, n-hexane, n-decane, toluene, styrene,
