Simona Abbà

My research is currently focussed on:

  • de novo genome assembly and RNAseq analysis of phytoplasmas;
  • in silico study of the grapevine/phytoplasma interactions through a system biology approach;
  • SNP genotyping in grapevine;
  • functional characterization of proteins in Cryphonectria parasitica.

I am also collaborating to the “V2P2 repository” project. This e-infrastructure is designed to preserve and share research data about plant-microbe interactions, such as:

  • high-resolution images showing plant viral infections, plant disease symptoms, insect vectors, plant viral particles, soil fungi, mycorrhized roots, ultrastructure of plant cells, etc.
  • Grey Literature (books of abstract, posters, logs, notes, laboratory notebooks
  • data about the IVV collection of plant virus and phytoplasmas.

During my PhD, I explored the interactions between plants and mycorrhizal fungi (Tuber borchii, in particular). More recently, during my post-doc, I was interested in the possibility of exploiting the ericoid mycorrhizal fungus Oidiodendron maius in the bioremediation of heavy metal-polluted soils. These aspects were investigated mainly with biochemical, cell and molecular biology techniques, using Saccharomyces cerevisiae as a model organism to test gene mutations, analyze phenotypes and explore protein–protein interactions (interactomics).
