Acetohydroxyacid synthase mutations conferring resistance to imidazolinone or sulfonylurea herbicides in sunflower
The molecular breeding tools described herein create the basis for rapidly identifying new mutations in AHAS and performing marker-assisted selection of herbicide resistance genes in sunflower.
Downy mildew (Pl8 and Pl14) and rust (RAdv) resistance genes reside in close proximity to tandemly duplicated clusters of non-TIR-like NBS-LRR-encoding genes on sunflower chromosomes 1 and 13
The genomic localization and sequence similarity of the novel non-Toll/interleukin-1 receptor (TIR)-like NBS-LRR RGCs suggests that they originated from tandem duplications, and six of the seven predicted R GCs have intact open reading frames and reside in genomic segments with abundant transposable elements.
Evaluation of genomic selection training population designs and genotyping strategies in plant breeding programs using simulation
This study provides a guide, enabling resource allocation to be opti-mized between genotyping and phenotyping investment dependent on the population under development, to enable genomic selection in early genera -tion individuals.
Cytogenetic analysis of autosomal polymorphism in Graomys griseoflavus (Rodentia, Cricetidae)
South American phyllotine Graomys griseoflavus specimens were collected in eight localities of central Argentina and cytogenetically analysed, revealing numerical karyotype variability explained by successive RFs, starting from a karyotypes with 2n = 42.
Phylogenetic relationships among Robertsonian karyomorphs of Graomys griseoflavus (Rodentia, Muridae) by mitochondrial cytochrome b DNA sequencing.
Three trees were produced showing the 2n = 38-34 karyomorphs grouped in a single clade while the 2 n = 42-41 animals formed a different one, in agreement with a hypothesis of a single origin for 2n-34 Robertsonian karyomorphic animals from the ancestral 1n = 42.
SMART – Sunflower Mutant population And Reverse genetic Tool for crop improvement
A “chemically induced mutated genetic resource for detecting SNP by TILLING” in sunflower to create new traits to optimize the EMS mutagenesis quality and identify traits of interest is developed.

Genetic variability of guanaco and llama populations in Argentina
Isolation and characterization of 10 polymorphic dinucleotide microsatellite markers for llama and guanaco
Five polymorphic dinucleotide microsatellite markers from llama and five from guanaco were isolated and characterized and all loci were assayed on wildllamas and guanacos from Argentina, as all of the primers were able to amplify in both specie s.
An assessment of the relationships among species of Camelidae by satellite DNA comparisons.
Southern hybridizations, using camel restriction fragments as probes, indicated that satellite DNAs in all camelids examined have been conserved since the last common ancestor about 5-10 MY ago.
