Fecha de publicación: | 18-jun-2018 | Editor: | Nature Publishing Group | Citación: | Scientific reports 8 (1) 9268 (2018) | Resumen: | Plant tolerance to freezing temperatures is governed by endogenous constitutive components and environmental inducing factors. Nitric oxide (NO) is one of the endogenous components that participate in freezing tolerance regulation. A combined metabolomic and transcriptomic characterization of NO-deficient nia1,2noa1-2 mutant plants suggests that NO acts attenuating the production and accumulation of osmoprotective and regulatory metabolites, such as sugars and polyamines, stress-related hormones, such as ABA and jasmonates, and antioxidants, such as anthocyanins and flavonoids. Accordingly, NO-deficient plants are constitutively more freezing tolerant than wild type plants. | Descripción: | 10 p.-6 fig. | Versión del editor: | https://doi.org/10.1038/s41598-018-27668-8 | URI: | http://hdl.handle.net/10261/167435 | DOI: | 10.1038/s41598-018-27668-8 | ISSN: | 2045-2322 | E-ISSN: | 2045-2322 |
