Caracterización molecular de mutantes derivadas del genotipo mutador de cloroplastos de cebada
Colombo, Noemi (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2008)La coordinación de la expresión génica entre los genomas nuclear, plastídico y mitocondrial es de importancia crucial para las células vegetales. Un caso particular de la interacción núcleo-plástido está dado por los genes ... -
Efficiency of cytogenetic methods in detecting a chromosome rearrangement induced by ionizing radiation in a cultivated chili pepper line (Capsicum baccatum var. pendulum – Solanaceae)
Scaldaferro, Marisel Analía; Grabiele, Mauro; Seijo, Jose Guillermo; Debat, Humberto Julio; Romero, María Victoria; Ducasse, Daniel Adrian; Prina, Alberto Raul; Moscone, Eduardo Alberto (2014)Purpose: To locate transient chromosome aberrations on a selected pepper cultivar and determine the tracing efficiency of different cytogenetic methods. Materials and methods: Seeds from Capsicum baccatum var. pendulum ... -
Estudio de la variabilidad genética inducida por el genotipo mutador de cloroplastos de la cebada a través de la técnica de TILLING
Lencina, Franco (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 ... -
Induced mutations in crop plants : mutants of scientific and/or agronomic interest at the Institute of Genetics “Ewald A. Favret” = Mutaciones inducidas en plantas cultivadas : mutantes de interés interés científico y/o agronómico en el Instituto de Genética “Ewald A. Favret”
Landau, Alejandra Mabel; Brizuela, Vanina Elizabeth; Lencina, Franco Daniel; Martinez, Alicia Ester; Tcach, Mauricio Alfredo; Diaz, Daniel Gustavo; Pacheco, Maria Gabriela; Prina, Alberto Raul (Universidad San Francisco de Quito, 2021-05)The use of induced mutations techniques in crop plants at Instituto de Genética "Ewald A. Favret" (IGEAF) INTA, started in 1949, with the pioneer work of Ewald Favret, who studied the effects of physical and chemical ... -
Isolation and characterization of a new imidazolinone tolerant mutant in cotton
Tcach, Mauricio Alfredo; Landau, Alejandra Mabel; Montenegro, Alex; Diaz, Daniel Gustavo; Acuña, Carlos; Prina, Alberto Raul (Wiley, 2022-07)Cotton cultivars resistant to different herbicides have generated important advances in crop management. There is a wide range of cotton resistance to herbicides, however, commercial imidazolinone (IMI)-tolerant cultivars ... -
Mutation Breeding for Sustainable Food Production in Latin America and the Caribbean Under Climate Change
González Cepero, María Caridad; Gómez Pando, Luz; De Andrade, Alexander; Arguello Delgado, Juan Felix; Nakayama Nakashima, Héctor; Landau, Alejandra Mabel; Prina, Alberto Raul; Rodríguez García, Mayra; Suchini Farfan, Aura; de la Cruz Torres, Eulogio (Springer Nature, 2023)The region of Latin America and the Caribbean is characterized by the great diversity of crops and environmental conditions where the crops coexist under the effects of different abiotic and biotic stresses, which impact ... -
Plastome mutations and recombination events in barley chloroplast mutator seedlings
Landau, Alejandra Mabel; Lencina, Franco; Pacheco, Maria Gabriela; Prina, Alberto Raul (2016)The barley chloroplast mutator (cpm) is an allele of a nuclear gene that when homozygous induces several types of cytoplasmically inherited chlorophyll deficiencies. In this work, a plastome Targeting Induced Local Lesions ... -
The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings
Lencina, Franco; Landau, Alejandra Mabel; Petterson, Maria Elizabeth; Pacheco, Maria Gabriela; Kobayashi, K.; Prina, Alberto Raul (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 ... -
The barley chloroplast mutator (cpm) mutant: all roads lead to the Msh1 gene
Lencina, Franco Daniel; Landau, Alejandra Mabel; Prina, Alberto Raul (MDPI, 2022-02)The barley chloroplast mutator (cpm) is a nuclear gene mutant that induces a wide spectrum of cytoplasmically inherited chlorophyll deficiencies. Plastome instability of cpm seedlings was determined by identification of a ...
