ABA and GA 3 increase carbon allocation in different organs of grapevine plants by inducing accumulation of non-structural carbohydrates in leaves, enhancement of phloem area and expression of sugar transporters
(2016)Grape quality for winemaking depends on sugar accumulation and metabolism in berries. Abscisic acid (ABA) and gibberellins (GAs) have been reported to control sugar allocation in economically important crops, although the ... -
ABA and GA3 regulate the synthesis of primary and secondary metabolites related to alleviation from biotic and abiotic stresses in grapevine
(2017-03)Plants are able to synthesize a large number of organic compounds. Among them, primary metabolites are known to participate in plant growth and development, whereas secondary metabolites are mostly involved in defense and ... -
High Temperature Alters Anthocyanin Concentration and Composition in Grape Berries of Malbec, Merlot, and Pinot Noir in a Cultivar-Dependent Manner
(MDPI, 2022-03)Climate is determinant for grapevine geographical distribution, berry attributes, and wine quality. Due to climate change, a 2–4 °C increase in mean diurnal temperature is predicted by the end of the century for the most ... -
Loss of anthocyanins and modification of the anthocyanin profiles ingrape berries of Malbec and Bonarda grown under high temperature conditions
(2017)Malbec and Bonarda are the two most widely cultivated grape varieties in Argentina, and their derivedred wines are recognized worldwide, being their intense color a major quality trait. The temperature dur-ing fruit ripening ... -
Nitric oxide and abscisic acid regulate osmoprotective and antioxidative mechanisms related to water stress tolerance of grapevines
(Wiley, 2021-03)Background and Aims: Exogenously applied nitric oxide (NO) and abscisic acid (ABA) are known to improve the tolerance of plants to abiotic stress. The effects of NO and ABA applications on physiological and metabolic ... -
Role of ABA and Gibberellin A3 on gene expression pattern of sugar transporters and invertases in Vitis vinifera cv. Malbec during berry ripening
(2018-03)Sugars are key constituents that affect quality of grape berries, and consequently the grape metabolic profile relevant to wine’s industry. However, enzymes and transporter genes expression involved in sugar transport at ... -
Solar UV-B radiation modifies the proportion of volatile organic compounds in flowers of field-grown grapevine (Vitis vinifera L.) cv. Malbec
(2014-11)Ultraviolet-B solar radiation (UV-B) is an environmental signal with biological effects in different plant tissues. Recent investigations reported dramatic changes of terpenes with a protective role in plant tissues submitted ... -
Transcriptome changes in grapevine (Vitis viniferaL.) cv. Malbec leaves induced by ultraviolet-B radiation
(2010-10)Ultraviolet-B radiation (UV-B, 280-315 nm) is a natural component of sunlight, which has numerous regulatory effects on plant physiology. The nature of the response to UV-B is dependent on fluence rate, dose, duration and ... -
Volatile organic compounds characterized from grapevine (Vitis vinifera L. cv. Malbec) berries increase at pre-harvest and in response to UV-B radiation
(2013-12)Ultraviolet-B solar radiation (UV-B) is an environmental signal with biological effects in plant tissues. Recent investigations have assigned a protective role of volatile organic compounds (VOCs) in plant tissues submitted ...
