Comparative genomics reveals putative copper tolerance genes in a Fusarium oxysporum strain.

ABSTRACT: Copper has been widely used as a main component in fungicides due to its versatility and effectivity. However, copper contamination from the environment creates selective pressure for the emergence of copper-tolerant pathogenic fungal strains that may proliferate and further cause damage to important agricultural crops. Although some studies focused on specific cellular mechanisms of copper tolerance, comprehensive genomic data are lacking. Here, we examined the genes potentially involved in copper tolerance by conducting a comparative analysis of newly sequenced genomes of 2 Fusarium oxysporum strains, IB-SN1W (copper-tolerant) and Foc-3429 (copper-sensitive), with other Fusarium species. Whole-genome assembly and annotation identified 10 core chromosomes shared between the 2 strains. Pro
