Biografía
My research topic has been mainly focused on the study of fruit-pathogen interactions, mostly on orange-Penicillium digitatum and apple-Penicillum expansum interactions. I have used genomics, transcriptomics and metabolomics to increase our knowledge on the fruit responses after the infection of the pathogen or after elicitation of induced resistance, and on the mechanisms of virulence and pathogenicity of the pathogen. From the point of view of the fruit, my results have shown that secondary metabolites, mainly phenylpropanoids, and ethylene play important roles in the induction of resistance in citrus fruit. I have also participated in unravelling the molecular responses of citrus fruit to moderate dehydration by using a fruit specific ABA-deficient mutant. During my last contracts I was more focused on the pathogen and, our analysis on the P. digitatum genome has established the molecular basis for the inability of this species to assimilate nitrate or produce the secondary metabolites patulin and penicillin. P. expansum is the Penicillium species with the largest potential for the production of secondary metabolites; however, neither patulin nor citrinin are required by the fungus to successfully infect apples.
During my research career I have been also involved in the study of the quality of tomatoes and pepper. We have identified the MYB12 transcription factor, which plays an important role regulating the flavonoid pathway, as a responsible of the pink color in tomato. Regarding pepper fruits, we have explored the biochemical diversity present within the wild and cultivated pepper germplams using metabolomics, and we have elucidated the molecular mechanisms underlying the production of flavor and health related compounds. I have also participated in the study of differential tomato transcriptomic responses induced by Pepino mosaic virus isolates, and in the characterization of the tomato FRUITFULL transcription factor that regulates ethylene-independent aspects of fruit ripening.
At present, I am focused on two main research lines that are settled over my previous experience, but that also aim to improve methodologies, designs, and analyses:
- Take advantage of omics analysis and the availability of fungal genomes to provide a comprehensive understanding the pathogenicity/virulence specificity. After high-throughput analysis, and based on the comparison of the different Penicillium spp. and another necrotroph pathogens, we can discover putative effectors involved in the pathogenicity/virulence of P. digitatum and P. expansum.
- Using the genome-wide analysis of different Penicillium spp. in order to reveal and characterize putative gene clusters and master regulators for different secondary metabolites, such as mycotoxins. I am part of the MICOFOOD (National network on mycotoxins and toxigenic fungi and their decontamination processes).
