Fulvia fulva [syn. Cladosporium fulvum, Passalora fulva] races in Argentina are evolving through genetic changes and carry polymorphic avr and ecp gene sequences

The aim of this work was to study further the population Fulvia fulva [syn. Cladosporium fulvum, Passalora fulva] in Argentina particularly terms diversity at genetic level by means ISSR. Also, we studied polymorphisms within avr and ecp sequences, what incidentally might lead development new races. Argentinian tomato cultivars only are affected two races F. data provide here indicates that populations these under an evolutionary process. Representatives them had several coding sequences effectors, but they not constrained genes, probably because, based on field data, resistant available. Most observed genes were deletions or insertions (INDELs) single nucleotide (SNPs). Therefore, environment management practices most important factors driving evolution explain why pathogen is driven pathogenic race level.
