Abstract: The present disclosure is directed to methods of genetically detecting or generating a peanut line that is resistant to peanut smut infection. The disclosure also relates to cultivation of smut resistant peanut lines and the cessation or prevention of peanut smut in a given geographic area.

Abstract: The present disclosure is directed to methods for verifying the genetic makeup of a target product, for example, products in a supply chain. The methods relate to the use of genomics for confirming or verifying the genetic makeup of the target product. The methods also relate to the use of genomics for detecting the presence or absence of one or more gene variants associated with a specific phenotypic quality or characteristic in the target product. The presently disclosed method verifies and/or detects certain genetic markers of the target product using whole genome sequencing (WGS) to access the entire genome.

Abstract: The invention includes a method of screening a biological sample for contamination by sequencing a first biological sample at a first depth to generate a first nucleotide sequence; determining map coordinates for one or more homozygous loci in the first nucleotide sequence; sequencing a second biological sample at a second depth to generate a second nucleotide sequence, wherein the second depth is lower than the first depth; determining loci in the second nucleotide sequence at the determined map coordinates; and comparing the one or more homozygous loci in the first nucleotide sequence with the determined loci in the second nucleotide sequence.
