Genomic and phenotypic comparison between similar wine yeast strains of Saccharomyces cerevisiae from different geographic origins
(Wiley, 2010-05)Aims: To study genomic and phenotypic changes in wine yeasts produced in short time periods analysing yeast strains possibly derived from commercial strains recently dispersed. Methods and Results: We conducted a genomic ... -
Simultaneous Inoculation of Malbec (Vitis vinifera) Musts with Yeast and Bacteria: Effects on Fermentation Performance, Sensory and Sanitary Attributes of Wines
(Faculty of Food Technology and Biotechnology, University of Zagreb (Croacia), 2009)Malolactic fermentation has important consequences for the quality of wine. The present study analyzes the effect of timing of inoculation with bacteria on the performance of alcoholic and malolactic fermentation in Malbec ... -
Yeast identification in grape juice concentrates from Argentina
(Wiley, 2008-02)Aims: The purpose of this study was to identify yeast species present in spoiled and unspoiled grape juice concentrates from Argentine industries. Methods and Results: Osmophilic and osmotolerant yeasts were isolated from ... -
Modeling vegetative vigour in grapevine: unraveling underlying mechanisms
(Elsevier, 2020-12)Mechanistic modeling constitutes a powerful tool to unravel complex biological phenomena. This study describes the construction of a mechanistic, dynamic model for grapevine plant growth and canopy biomass (vigor). To ... -
A dynamic model for sodium intoxication unravels salt tolerance in grapevine (Vitis vinifera L.) rootstocks
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12)A correct selection of salt-tolerant plants should consider the relative effects of the various existing tolerance mechanisms. When toxic ions, like Na+, reach the leaves, they affect the photosynthetic apparatus, reducing ... -
Non‐structural carbohydrates and sugar export in grapevine leaves exposed to different light regimes
(Wiley, 2020-11)Light is a main environmental factor that determines leaf microclimate within the vine, as well as its photosynthesis and carbohydrate metabolism. This study aimed to examine the relationships between photosynthesis, ... -
A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems
(Oxford University Press, 2020-09)Background and Aims: Scaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas ... -
Generation of a non-transgenic genetically improved yeast strain for wine production from nitrogen-deficient musts
(MDPI, 2020)The yeast Saccharomyces cerevisiae is the main species responsible for the process that involves the transformation of grape must into wine, with the initial nitrogen in the grape must being vital for it. One of the main ... -
High temperature during the budswell phase of grapevines increases shoot water transport capacity
(Elsevier, 2020-09)Knowledge about heat acclimation in perennial plants is limited. Our hypotheses were (i) that high temperature during budswell before budbreak elicits acclimation in grapevines that is mediated by greater water transport ... -
Effect of leaf‐to‐fruit ratios on phenolic and sensory profiles of Malbec wines from single high‐wire‐trellised vineyards
(Wiley, 2020-08)BACKGROUND: The single high‐wire system is a free canopy trellis system suitable for warm to hot climates. In a global warming scenario, it arouses as a technological solution since it prevents berry overheating and sunburn. ... -
Rootstocks increase grapevine tolerance to NaCl through ion compartmentalization and exclusion
(Springer, 2020-09)The productivity of Vitis vinifera L. is limited by salinity, especially under water and drainage deficits, and could aggravate with climate change. The use of tolerant rootstocks is a strategy against salinity that helps ... -
Espacios agrícolas periurbanos en el siglo XXI
(Instituto CIFOT. Universidad Nacional de Cuyo, 2020)La agricultura en los espacios periurbanos de la mayoría de las ciudades medianas y grandes de Argentina tiene una estructura basada en la pequeña escala, con mano de obra familiar y conformada en gran medida por el proceso ... -
Spatial distribution of soil carbon storage in desert shrubland ecosystems of northwest Mexico
(Elsevier, 2020-12)The scarce information about soil carbon (C) storage in water-stressed ecosystems limits our understanding on soil contribution to the C cycle in arid zones. This study, performed in arid NW México: (i) estimated soil ... -
Influencia de dos técnicas de maceración sobre la composición polifenólica, aromática y las características organolépticas de vinos cv. Merlot
(Infonet, 2007)La técnica de maceración empleada, así como la gestión de la misma, condiciona fuertemente el estilo de vino a obtener. En el marco de un ensayo llevado a cabo en la planta piloto del Centro de Estudios de Enología de ... -
Piranoantocianos : nuevos pigmentos en los vinos tintos. Aspectos científicos e implicancias tecnológicas.
(2006-08)El universo del color de los vinos tintos es complejo, dentro del mismo actúan diversos compuestos que provienen de la uva y otros que son formados durante los procesos de vinificación y añejamiento de los vinos. Las ... -
Modulation of flavonoid biosynthetic pathway genes and anthocyanins due to virus infection in grapevine (Vitis viniferaL.) leaves
(BMC, 2010-08)Background: Symptoms of grapevine leafroll disease (GLRD) in red-fruited wine grape (Vitis vinifera L.) cultivars consist of green veins and red and reddish-purple discoloration of inter-veinal areas of leaves. The ... -
Effect of extended maceration and ethanol concentration on the extraction and evolution of phenolics, colour components and sensory attributes of Merlot wines
(Wiley, 2013-02)Background and Aims: Anecdotal evidence suggests that there may be a synergistic effect of ethanol (EtOH ) and prolonged skin contact on the extraction of certain phenolics that may negatively impact wine sensory properties. ... -
