Our group focuses its research on:

Tolerance of horticultural crops and fruity trees to multiple abiotic stresses

Horticultural crops and fruity trees require a tight control of the cultivation process to ensure yield and quality over the years. However, environmental factors such as temperature, light intensity, and water and nutrient availability can induce abiotic stresses in fruity trees and horticultural plants that can limit the overall productivity and profits obtained from their cultivation.
In this section of the ANTIOX-AgriFood Biotech group, we investigate the physiology behind fruity trees and horticultural plants subjected to multiple abiotic stresses like drought, high light, extreme temperatures or nutrient starvation to enhance control and efficiency of crops and orchards under these circumstances.

Biostimulants and biofertilisers

During the last decade there has been a growing demand for sustainable and eco-friendly agriculture. Biofertilisers and biostimulants, which are based on natural compounds and microorganisms with beneficial properties to crop plants, are presently essential for the development of an environmentally-friendly agriculture. In this context, the greatest challenge in developing these products is to ensure productivity and efficiency rates in crops, so that farmers do not compromise their profits.
At the ANTIOX-AgriFood Biotech group, we help developing new biostimulants and biofertilizers, and also evaluate action mechanisms of newly developed products with the analysis of the plant response to the application of these products. Our final goal is to help developing new products that can be effective and efficient for an extensive use in agriculture.

Hormonal profiling

The ANTIOX-AgriFood Biotech group has developed and mastered a rapid and sensitive method of hormonal profiling of complex plant samples by liquid chromatography coupled to electrospray ionization tandem mass spectrometry (UPLC/ESI-MS/MS) for more than 10 years. Our system enables the simultaneus detection of the main phytohormones involved in plant growth and stress resistance, which enables better understanding of the requirements of the plant cultivars at diferent phases of their lifespand and allows the development of different strategies to enhance their performance.

Hormonal cross-talk

Plant phytohormones have been extensively studied over the last decades. However, recent studies show that the interaction between different phytohormones is essential for correct growth and acclimation of plants.
The Antiox-AgriFood Biotech group aims for a better understanding of environmental and developmental factors influencing interactions between plant hormones, along with regulatory and signaling events involved in their cross-talk.

Fruit physiology and technology

Fruit development and ripening are complex processes that directly affect their final quality. In this sense, it is essential to guarantee a correct fruit development so that it can acquire organoleptic properties to meet consumers’ demands, along with all nutritional and bioactive components that make fruit consumption beneficial for human health.
In this part of the ANTIOX-AgriFood Biotech group, we focus our research to better understand the physiology behind fruit development and ripening on tree and during the postharvest period, so that we can enhance fruit quality in terms of their organoleptic properties and nutritional value.

Flower senescence and longevity

Flowers are highly appreciated worldwide because of their beauty, aroma and bright colours, which make them the focus in multiple social events. However, their shelf-life is usually short, both in cut and uncut flowers and, although their market generates great profits, flower lifespan determines their final value.
For this reason, at the ANTIOX-AgriFood Biotech team we investigate mechanisms related to flower longevity and senescence, and help develop new products to enhance flower lifespan, so that consumers can enjoy flower beauty for longer periods.
