A candidate gene survey of quantitative trait loci affecting chemical composition in tomato fruit
(Society for Experimental Biology, 2008-07)In tomato, numerous wild-related species have been demonstrated to be untapped sources of valuable genetic variability, including pathogen-resistance genes, nutritional, and industrial quality traits. From a collection of ... -
Allelic differences in a vacuolar invertase affect Arabidopsis growth at early plant development
(2016)Improving carbon fixation in order to enhance crop yield is a major goal in plant sciences. By quantitative trait locus (QTL) mapping, it has been demonstrated that a vacuolar invertase (vac-Inv) plays a key role in ... -
Association mapping in sunflower for sclerotinia head rot resistance
(BMC, 2012-06)Background: Sclerotinia Head Rot (SHR) is one of the most damaging diseases of sunflower in Europe, Argentina, and USA, causing average yield reductions of 10 to 20 %, but leading to total production loss under favorable ... -
Candidate Gene Approach for Parasite Resistance in Sheep – Variation in Immune Pathway Genes and Association with Fecal Egg Count
(Plos One, 2014-02-12)Sheep chromosome 3 (Oar3) has the largest number of QTLs reported to be significantly associated with resistance to gastro-intestinal nematodes. This study aimed to identify single nucleotide polymorphisms (SNPs) within ... -
Diversidad genómica y mapeo por asociación para la resistencia a la podredumbre húmeda del capítulo causada por Sclerotinia sclerotiorum en girasol
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2015)Argentina tiene una larga tradición en el mejoramiento de girasol, siendo su germoplasma un recurso genético invaluable a nivel mundial. Nuestro país es el tercer exportador mundial de aceite crudo y segundo exportador de ... -
Estudio de la resistencia a Sclerotinia sclerotiorum en líneas endocriadas de girasol
(Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, 2014)La podredumbre húmeda del capítulo (PHC), causada por Sclerotinia sclerotiorum, es una de las limitante más importantes para el cultivo del girasol. Este trabajo tuvo como objetivo identificar las regiones del genoma de ... -
Genetic dissection of vitamin E biosynthesis in tomato
(Society for Experimental Biology, 2011-07)Vegetables are critical for human health as they are a source of multiple vitamins including vitamin E (VTE). In plants, the synthesis of VTE compounds, tocopherol and tocotrienol, derives from precursors of the shikimate ... -
Genetic diversity of Mycobacterium avium sp. Paratuberculosis by mycobacterial interspersed repetitive unit–variable number tandem repeat and multi‑locus short‑sequence repeat one‑sentence summary : genetic diversity of Mycobacterium avium sp. Paratuberculosis isolates
(Wolters Kluwer Medknow, 2021-03)Background: Paratuberculosis is an enteric disease caused by Mycobacterium avium sp. paratuberculosis (MAP) that affects mainly ruminant producing losses to the livestock industry. Many molecular epidemiological methods ... -
Identification and characterization of metabolite quantitative trait loci in tomato leaves and comparison with those reported for fruits and seeds
(Springer, 2019-04)Introduction: To date, most studies of natural variation and metabolite quantitative trait loci (mQTL) in tomato have focused on fruit metabolism, leaving aside the identification of genomic regions involved in the ... -
Loci de caracteres cuantitativos para rasgos reproductivos en bovinos lecheros locales
(Sociedad Argentina de Genética, 2022-10)Introducción: La intensa selección para producción lechera junto con una consideración insuficiente de parámetros de fertilidad y salud, sumado a las correlaciones genéticas antagonistas o cercanas a cero entre caracteres ... -
Natural occurring epialleles determine vitamin E accumulation in tomato fruits
(2014-07)Vitamin E (VTE) content is a low heritability nutritional trait for which the genetic determinants are poorly understood. Here, we focus on a previously detected major tomato VTE quantitative trait loci (QTL; mQTL9-2-6) ... -
Quantitative trait loci exploration and characterization of gestation length in Holstein cattle
(Elsevier, 2024-02)Gestation length (GL) is a moderately heritable trait in cattle with economic and management implications. This study aimed to characterize the gestation length of an Argentinian Holstein cattle population, understand ... -
Seed dormancy QTL identification across a Sorghum bicolor segregating population
(2016)Pre-harvest sprouting (PHS) in Sorghum bicolor is one of the main constrains for its production in the central region of Argentina, as grain maturation often coincides with rainy or high environmental humidity conditions. ... -
The genetic architecture of photosynthesis and plant growthrelated traits in tomato
(Wiley, 2018-02)To identify genomic regions involved in the regulation of fundamental physiological processes such as photosynthesis and respiration, a population of Solanum pennellii introgression lines was analyzed. We determined ...
