Interplay among Antioxidant System, Hormone Profile and Carbohydrate Metabolism during Bud Dormancy Breaking in a High-Chill Peach Variety

(1) Background: Prunus species have the ability to suspend (induce dormancy) and restart growth, in an intricate process in which environmental and physiological factors interact. (2) Methods: In this work, we studied the evolution of sugars, antioxidant metabolism, and abscisic acid (ABA) and gibbe...

description (1) Background: Prunus species have the ability to suspend (induce dormancy) and restart growth, in an intricate process in which environmental and physiological factors interact. (2) Methods: In this work, we studied the evolution of sugars, antioxidant metabolism, and abscisic acid (ABA) and gibberellins (GAs) levels during bud dormancy evolution in a high-chill peach variety, grown for two seasons in two different geographical areas with different annual media temperature, a cold (CA) and a temperate area (TA). (3) Results: In both areas, starch content reached a peak at ecodormancy, and then decreased at dormancy release (DR). Sorbitol and sucrose declined at DR, mainly in the CA. In contrast, glucose and fructose levels progressively rose until DR. A decline in ascorbate peroxidase, dehydroascorbate reductase, superoxide dismutase and catalase activities occurred in both seasons at DR. Moreover, the H2O2-sensitive SOD isoenzymes, Fe-SOD and Cu,Zn-SOD, and two novel peroxidase isoenzymes, were detected. Overall, these results suggest the occurrence of a controlled oxidative stress during DR. GA7 was the major bioactive GA in both areas, the evolution of its levels being different between seasons and areas. In contrast, ABA content decreased during the dormancy period in both areas, resulting in a reduction in the ABA/total GAs ratio, being more evident in the CA. (4) Conclusion: A possible interaction sugars-hormones-ROS could take place in high-chill peach buds, favoring the DR process, suggesting that, in addition to sugar metabolism, redox interactions can govern bud DR, regardless of chilling requirements.

(2) Métodos: En este trabajo, estudiamos la evolución de los azúcares, el metabolismo antioxidante y los niveles de ácido abscísico (ABA) y giberelinas (GAs) durante la evolución de la dormancia de las yemas en una variedad de melocotón de alta necesidad de frío, cultivada durante dos temporadas en dos áreas geográficas diferentes con diferentes temperaturas medias anuales, un área fría (CA) y un área templada (TA). (3) Resultados: En ambas áreas, el contenido de almidón alcanzó un pico en la eco-dormancia y luego disminuyó en la liberación de dormancia (DR). El sorbitol y la sacarosa disminuyeron en DR, principalmente en el área CA. En contraste, los niveles de glucosa y fructosa aumentaron progresivamente hasta la DR. Se produjo una disminución en las actividades de ascorbato peroxidasa, deshidroascorbato reductasa, superóxido dismutasa y catalasa en ambas temporadas en DR. Además, se detectaron las isoenzimas sensibles al H2O2, Fe-SOD y Cu,Zn-SOD, y dos nuevas isoenzimas de peroxidasa. En general, estos resultados sugieren la ocurrencia de un estrés oxidativo controlado durante la DR. La GA7 fue la principal GA bioactiva en ambas áreas, siendo diferente la evolución de sus niveles entre temporadas y áreas. En contraste, el contenido de ABA disminuyó durante el período de dormancia en ambas áreas, lo que resultó en una reducción en la relación ABA/GAs totales, siendo más evidente en el CA. (4) Conclusión: Podría tener lugar una posible interacción entre azúcares-hormonas-ROS en las yemas de melocotón de alta necesidad de frío, favoreciendo el proceso de DR, lo que sugiere que, además del metabolismo de azúcares, las interacciones redox pueden regir la DR de las yemas, independientemente de los requisitos de frío.Agricultura y VeterinariaCiencias AmbientalesCiencias de la Alimentación2021info:eu-repo/semantics/articlehttp://hdl.handle.net/10952/7688https://doi.org/10.3390/antiox10040560reponame:RIUCAM.
