Integral analysis of the beneficial effects of gaseous technologies to preserve the quality and safety of fruit during postharvest and identification of genes and biomarkers to develop new genomic and technological strategies.

Objectives

  • Understanding of the molecular bases of the beneficial effect of high CO2 concentration to identify the biomarkers associated with quality traits.
  • Mechanisms behind the technologies that induce the accumulation of metabolites with beneficial properties for health.
  • Characterization of genes and transcription factors associated with the improvement of quality in red fruit.
  • Functionality of defence proteins and potential industrial application.
  • Development of non-contaminant technologies for agri-food industries.
  • Omics in postharvest research.
  • Characterization in vivo of the function of genes involved in cell wall structure and synthesis of anthocyanins.

Research Lines

  • Basic mechanisms of postharvest technologies to maintain fruit quality and improve the storage period.
