Four large indels in barley chloroplast mutator (cpm) seedlings reinforce the hypothesis of a malfunction in the MMR system
Lencina, Franco Daniel; Prina, Alberto Raul; Pacheco, Maria Gabriela; Kobayashi, Ken; Landau, Alejandra Mabel (MDPI, 2025-09)A mutation detection strategy based on mismatch digestion was applied previously in barley seedlings carrying the chloroplast mutator (cpm) genotype through many generations. Sixty-one mutations were detected along with ... -
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 ... -
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 ...
