The pattern of polymorphism across scaffold DS571171. Polymorphic sites on scaffold DS571171 are represented by shaded squares: black for bases that match the HM-1:IMSS reference; light grey for bases that differ from the reference; dark grey for heterozygous positions; white for positions where no base was assigned. Three positions (marked with asterisks) had an additional variant base in one strain. Each row represents a strain in the following order from top to bottom: reference sequence (HM-1:IMSS), HM-1A, HM-1B, Rahman, 2592100, PVBM08B, PVBM08F, IULA:1092:1, HK-9, MS84-1373, MS27-5030. Sites in coding sequences are marked with black lines above the figure.
