A genome-wide association study unveils key chromosome regions involved in determining sodium accumulation in wheat under conditions of low potassium supply
Moriconi, Jorge I.; Silva, Martha; Zhang, Junli; Tranquilli, Gabriela; Santa-María, Guillermo E. (Elsevier, 2022-05-30)Improving nutrient use efficiency is an important objective in modern breeding programs. In this work, we examined potassium utilization efficiency (KUtE) and traits potentially related to it in a formerly genotyped, ... -
Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes
Garbus, Ingrid; Romero, José Rodolfo; Miroslav, Valarik; Vanzurova, Hana; Karafiatova, Miroslava; Caccamo, Mario; Dolezel, Jaroslav; Tranquilli, Gabriela; Helguera, Marcelo; Echenique, Carmen Viviana (2015)Background: The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ... -
Criterios de selección fenotípica en el mejoramiento vegetal: mirando debajo de la alfombra
Di Salvo, Luciana P.; Tranquilli, Gabriela; García de Salamone, Inés E. (INTA, 2022-11-03)¿En qué punto nos encontramos? Creciente demanda mundial de alimentos. Necesidad de aumentar la productividad de los cultivos en forma sustentable. Contraste con los objetivos de la revolución verde del siglo XX: aumento ... -
Earliness per se variation in Argentine bread wheat varieties and mapping of QTLs in a recombinant inbred line population
Lombardo, Lucio; Ghione, Celina Elena; Nisi, María Mercedes; Tranquilli, Gabriela; Helguera, Marcelo (Springer, 2019-10)The occurrence of flowering time in wheat is affected not only by the vernalization and photoperiod response, but also by earliness per se (EPS). The effects of this trait facilitate the fine tunning of the life cycle for ... -
Effect of allelic variation at the Glu-3 / Gli-1 loci on breadmaking quality parameters in hexaploid wheat [Triticum aestivum L.]
Bonafede, Marcos; Tranquilli, Gabriela; Pfluger, Laura Alicia; Peña, Roberto Javier; Dubcovsky, Jorge (2015-03)Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
Nitcher, Rebecca; Pearce, Stephen; Tranquilli, Gabriela; Xiaoqin, Zhang; Dubcovsky, Jorge (2014-09)Precise regulation of flowering time is critical for plant reproductive success and, in cereals, to maximize grain yields. Seasonal cues including temperature and day length are integrated to regulate the timing of flowering. ... -
Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
Tranquilli, Gabriela; Lewis, Silvina; Kippes, Nestor; Dubcovsky, Jorge; Alvarez, María Alejandra (2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
New insight into the wheat chromosome 4 D structure and virtual gene order, relead by survey pyrosequencing
Helguera, Marcelo; Rivarola, Maximo Lisandro; Clavijo, Bernardo; Martis, Mihaela M.; Vanzetti, Leonardo Sebastian; Gonzalez, Sergio Alberto; Garbus, Ingrid; Leroy, Phillippe; Simková, Hana; Valárik, Miroslav; Caccamo, Mario; Dolezel, Jaroslav; Mayer, Klaus F.X.; Feuillet, Catherine; Tranquilli, Gabriela; Paniego, Norma Beatriz; Echenique, Carmen Viviana (2015)Survey sequencing of the bread wheat (Triticum aestivum L.) genome (AABBDD) has been approached through different strategies delivering important information. However, the current wheat sequence knowledge is not complete. ... -
Nitrogen–sulfur fertilisation effects on gluten composition and industrial quality in Argentinean bread wheat cultivars differing in apparent sulfur recovery
Arata, Agustin Francisco; Rogers, Willian; Tranquilli, Gabriela; Arrigoni, Adriana; Rondanini, Deborah Paola (CSIRO, 2021-03-12)Increasing wheat yield and grain quality is crucial for achieving profitable production systems. Genotype has an important role in determining potential grain end-use quality, because it defines the protein subunits stored ...
