Introduction
My research is focused on the study of fruit physiology and technology to understand mechanisms associated with fruit ripening and senescence both on preharvest and postharvest applications. I also develop a research line of flower development and senescence where we investigate the events taking place once flowers are cut for commercialisation.

Article
Fresh-cut fruits in ready-to-eat packaging are convenient healthy snacks that can be composed of one type of fruit or a mixture of different fruits to attract consumer's attention. However, to date, no studies have been performed to determine whether fruit mixing could impair fruit quality traits or their shelf-life. Here, we aimed at evaluating qu...
Article
Plum is a stone fruit that stands out for having a short shelf-life because of its high susceptibility to rapid deterioration. Part of this deterioration is explained by fruit overripening. Recently, the role of melatonin in delaying postharvest decay has been investigated but its regulatory function during overripening is still under extensive deb...
Article
Epigenetic regulation is crucial to ensure a coordinated control of the different events that occur during fruit development and ripening. Sirtuins are NAD⁺-dependent histone deacetylases involved in the regulation of gene expression of many biological processes. However, their implications in the Rosaceae family remains unexplored. Accordingly, in...
Article
Cuticle integrity represents an important factor in fruit quality of sweet cherries. Plants hormones, especially abscisic acid (ABA), are involved in fruit cuticle integrity. The effect of pre-harvest application of abscisic acid on cherry fruit cuticles was investigated. Changes of the concentrations of several phytohormones, expression levels of...

Agricultural practices in grapevines management include water restrictions due to its positive effect on wine quality, especially when applied at fruit ripening. Although the effects of water stress in some groups of phytohormones have already been described in leaves and whole grapes, information regarding tissue-specific variations in hormones du...
Article
Mastic trees (Pistacia lentiscus L.) are dioecious perennial plants that are highly adapted to Mediterranean climates but display a high sensitivity to winter periods. In order to understand how sex, leaf phenology and ecological context could condition sensitivity to winter and associated mechanisms to acclimate to these conditions, photoinhibitio...

Oxylipins (compounds derived from the oxidation of polyunsaturated fatty acids) are essential in retrograde signaling emanating from plastids to the nucleus during plant developmental and stress responses. In this graphical review, we provide an overview of the chemical structure, biosynthesis and role of oxylipins, as both redox and hormonal signa...
Article
Heat stress has negative effects on plant performance, especially in photosynthesis and photoprotection. To withstand heat stress, plants modulate the steroid phytohormones, brassinosteroids (BRs). However, their regulation and functions in heat stress acclimation are still poorly understood. Plant growth, photoinhibition, photo-oxidative stress an...
Article
The ability of European pears (Pyrus communis L.) to ripen immediately after harvest is cultivar-dependent and relies on a range of physiological and biochemical events occurring during fruit growth and development that remain largely unknown. To gain further knowledge on these events, changes in the content of sugars, acids, major hormones and eth...
Article
Vitamin E, which includes both tocopherols and tocotrienols, comprises lipid-soluble antioxidants that modulate lipid peroxidation. Recently, significant advances have been made in our understanding of vitamin E biosynthesis, transport, and function. The phytyl moiety from chlorophyll degradation is used for tocopherol biosynthesis. An α-tocopherol...
Article
Although melatonin effects on postharvest fruit ripening have been studied in some detail, information is still scarce during pre-harvest. Here, we examined whether or not melatonin may exert a regulatory role during sweet cherries ripening in orchard trees. We evaluated (i) the endogenous variations in melatonin contents, in comparison to those of...

Climacteric and non-climacteric fruits are differentiated by the ripening process, in particular by the involvement of ethylene, high respiration rates and the nature of the process, being autocatalytic or not, respectively. Here, we focus on the biosynthesis, metabolism and function of three compounds (auxin, salicylic acid and melatonin) sharing...
Article
Although most studies to extend vase life in cut flowers have focused on flower senescence thus far, flower opening is a complex process of major biological significance in the determination of flower commercialization. In order to better understand flower opening, this study evaluated to what extent photoinhibition and photo-oxidative stress are a...

Sweet cherry, a non-climacteric fruit, is usually cold-stored during postharvest to prevent over-ripening. The aim of the study was to evaluate the role of abscisic acid (ABA) on fruit growth and ripening of this fruit, considering as well its putative implication in over-ripening and effects on quality. We measured the endogenous concentrations of...
