Accumulation of the genetic variations in a Verticillium dahliae population in a managed agricultural ecosystem. The genome of the parental race 1 strain of V. dahliae (VdLs.16) was set as the reference to call the genetic variations of single-nucleotide polymorphisms (SNPs) and insertions and deletions (In-Dels). The variations were called from the VdLs.16 population that was collected from a field planted with race 1-resistant lettuce over 6 years. a Statistics of the genetic variations from the VdLs.16 population collected in 2010, 2012, 2014, and 2015. The numbers in red and black letters represent the total amount of SNPs and In-Dels in VdLs.16 population, respectively. b Identification of SNPs in the VdLs.16 population. c Collection of the insertions and deletions (In-Dels) in the VdLs.16 population. The letters “I” and “D” represent the genetic variations of insertions and deletions, respectively
