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
Murcia, Mauro German; Pontin, Mariela Ana; Reinoso, Herminda; Baraldi, Rita; Bertazza, Gianpaolo; Gomez Talquenca, Gonzalo; Piccoli, Patricia Noemí; Bottini, Ambrosio Rubén (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
Murcia, Mauro German; Fontana, Ariel; Pontin, Mariela Ana; Baraldi, Rita; Bertazza, Gianpaolo; Piccoli, Patricia Noemí (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 ... -
Nitric oxide and abscisic acid regulate osmoprotective and antioxidative mechanisms related to water stress tolerance of grapevines
Pontin, Mariela Ana; Murcia, Mauro German; Bottini, Ambrosio Rubén; Fontana, Ariel; Bolcato, L.; Piccoli, Patricia Noemí (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
Murcia, Mauro German; Pontin, Mariela Ana; Piccoli, Patricia Noemí (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 ...
