Introgressed DNA within a Zea mays near-isogenic line displays lower levels of 24nt sRNA expression than the homologous region from the recurrent parent.

Abstract excerpt

Near-isogenic lines (NILs) are classical genetic tools used to dissect the actions of an allele when placed in a uniform genetic background. Although the goal of NIL creation is to examine the effects of a single allele in isolation, DNA linked to the allele is invariably retained and can confound any allele-specific effects. In addition to genetic variation, highly polymorphic species such as Zea mays will...
