Summary

We are interested in the study of complex traits that control fruit quality and disease resistance in melon (Cucumis melo L.). For this purpose we have been involved in the development of genetic populations and genomic tools to assist in the identification of the genes involved in the control of important traits as the type of fruit ripening or the accumulation of total sugars in the fruit flesh. The laboratory is also involved in the development of genomic and bioinformatic tools for their use in marker assisted selection programs in cucurbitaceae and solanaceae species, in collaboration with a partner seed company.

Research Projects

  • We are interested in the analysis of natural variability using re-sequencing of melon germplasm.
  • We are characterizing QTLs that are involved in fruit ripening in order to understand the molecular basis of the non-climacteric ripening found in the inodorus melon genotypes.
  • We are also interested in the characterization of QTLs that control the accumulation of sugars in the melon fruit with the objective of identifying  genes that can be used to develop varieties with stable sugar content.
  • In the framework of the Semillas Fitó-IRTA joint unit, we are interested in the development of molecular markers for their use in marker-assisted breeding of qualitative and quantitative traits in several plant species.
