Estudio de la variabilidad genética inducida por el genotipo mutador de cloroplastos de la cebada a través de la técnica de TILLING
(Departamento de Fisiología, Biología Molecular y Celular, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2018-11)El aislamiento de mutantes inducidas en el plastoma a partir de tratamientos con mutágenos químicos y/o físicos es muy poco exitoso. El genotipo mutador de los cloroplastos de la cebada (cpm) es único en monocotiledóneas ... -
Genetic Diversity of Rice stripe necrosis virus and New Insights into Evolution of the Genus Benyvirus
(MDPI, 2021-04-23)The rice stripe necrosis virus (RSNV) has been reported to infect rice in several countries in Africa and South America, but limited genomic data are currently publicly available. Here, eleven RSNV genomes were entirely ... -
Genetic Stability of Sexing Strains Based on the Locus swof Ceratitis Capitata
(Springer, 2002-09)This report deals with the process of improving the stability of medfly, Ceratitis capitata, genetic sexing strains (GSS) based on the swmutation on chromosome 2. This gene affects the rate of development as well as the ... -
Improvement of conditional Cre-lox system through application of the regulatory sequences from Cowpea mosaic virus
(Springer, 2018-04)To study the impact of regulatory sequences from Cowpea mosaic virus (CPMV) on Cre-mediated recombination rates, the cre gene was flanked by the 5′ non-translated and 3′ non-translated regions of CPMV. This cre configuration ... -
Molecular characterization of the garlic virus B genome and evidence of allexivirus recombination
(Springer, 2018)Molecular characterization is important for differentiating allexiviruses species, since detection by serological methods may be uncertain. Eight different species have been reported as infecting garlic: Garlic virus A, ... -
Origin of new lineages by recombination and mutation in avian infectious bronchitis virus from South America
(MDPI, 2022-10)The gammacoronavirus avian infectious bronchitis virus (IBV) is a highly contagious respiratory pathogen of primary economic importance to the global poultry industry. Two IBV lineages (GI-11 and GI-16) have been widely ... -
Reconstruction and characterization of full-length begomovirus and alphasatellite genomes infecting pepper through metagenomics
(MDPI, 2020-02)In northwestern Argentina (NWA), pepper crops are threatened by the emergence of begomoviruses due to the spread of its vector, Bemisia tabaci (Gennadius). The genus Begomovirus includes pathogens that can have a monopartite ... -
The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings
(Nature Publishing Group, 2019-07)Previously, through a TILLING (Targeting Induced Local Lesions in Genomes) approach applied on barley chloroplast mutator (cpm) seedlings a high frequency of polymorphisms in the rpl23 gene was detected. All the polymorphisms ... -
Tomato apical leaf curl virus: a novel, monopartite geminivirus detected in tomatoes in Argentina
(2018-01)Plant viruses that are members of the Geminiviridae family have circular single-stranded DNA (ssDNA) genome and are responsible for major crop diseases worldwide. We have identified and characterized a novel monopartite ... -
Transient gene expression in serum-free suspension-growing mammalian cells for the production of foot-and-mouth disease virus empty capsids
(PLOS, 2013-08-20)Foot-and-mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals. It produces severe economic losses in the livestock industry. Currently available vaccines are based on inactivated FMD virus (FMDV). ...
