Dissecting maize diversity in lowland South America : genetic structure and geographic distribution models
(2016)
Background: Maize landraces from South America have traditionally been assigned to two main categories: Andean and Tropical Lowland germplasm. However, the genetic structure and affiliations of the lowland gene pools have ...
Genetic Variation in FABP4 and Evaluation of Its Effects on Beef Cattle Fat Content
(2017-01-05)
FABP4 is a protein primarily expressed in adipocytes and macrophages that plays a key role in fatty acid trafficking and lipid hydrolysis. FABP4 gene polymorphisms have been associated with meat quality traits in cattle, ...
Genetic variation of xylem hydraulic properties shows that wood density is involved in adaptation to drought in Douglas-fir (Pseudotsuga menziesii (Mirb.))
(Springer, 2011-05)
Relationships between wood density and hydraulic efficiency and safety (hydraulic specific conductivity and vulnerability to cavitation, respectively) could clarify the physiological process explaining the impact of density ...
Genetic variability within accessions of the B73 maize inbred line
(2014)
The maize inbred line B73 has been extensively studied at the molecular level. Researchers now have access to the genome sequence of B73 as well as to databases of biallelic and multiallelic markers where functional ...
Genetic diversity and linkage disequilibrium in the Argentine public maize inbred line collection
(2017)
Knowledge of linkage disequilibrium (LD) patterns is considered a prerequisite for effective association mapping studies. However, no LD analysis in the Argentine public temperate maize collection has been reported to date. ...
Assessment of cold tolerance at early developmental stages and allelic variation at candidate genes in South American rice germplasm
(Springer, 2014-06)
Rice is susceptible to cold during early developmental stages. Most tolerant cultivars have been developed for other conditions than those occurring in South America’s rice growing areas, or their grain type is not suitable ...
High genetic variation in marginal fragmented populations at extreme climatic conditions of the Patagonian Cypress Austrocedrus chilensis
(Elsevier, 2010-03)
Knowledge about current patterns of genetic structure of populations together with the evolutionary history of a species helps to understand and predict the adaptation of populations to future climate change. We assayed ...
Two evolutionary units on the South American razor clam Ensis macha (Bivalvia: Pharidae): genetic and morphometric evidence
(Springer Nature, 2020-09)
The patterns of genetic and phenotypic diversity in marine life are the result of different geological and ecological processes. We analyzed the pattern of genetic and morphometric variation of the razor clam Ensis macha ...
Genetic diversity in a world germplasm collection of tall fescue
(2013)
Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ...
