Insights into the interaction between the fungal pathogen Hemileia vastatrix and its host Coffea arabica
Hemileia vastatrix is responsible for the most important disease of coffee (leaf rust), affecting cultivation worldwide. Biotrophic fungi (namely rusts) depend on living host cells for survival and are not amenable for in vitro culture, hampering molecular studies. in addition their economic impact, rust fungi are interesting biological and genetic models. The interaction between H. vastatrix races and coffee genotypes has been studied in detail at CIFC/IICT over the last 50 years at the genetic, cytological and biochemical levels, originating over 90% of the resistant coffee varieties currently cultivated throughout the world. In this project we are interested in identifying and characterizing genes putatively involved in the fungus-host interaction, as well as in characterizing the karyotype of H. vastatrix.
Results will be presented, from the comparison between stage-specific fungal EST libraries that allowed the identification and further characterization of genes differentially expressed in key stages of the fungus development process, to the characterization of H. vastatrix karyotype.
