The present invention relates to a high throughput method for the identification and detection of molecular markers wherein restriction fragments are generated and suitable adaptors comprising (sample-specific) identifiers are ligated. The adapter-ligated restriction fragments may be selectively amplified with adaptor compatible primers carrying selective nucleotides at their 3 end. The amplified adapter-ligated restriction fragments are, at least partly, sequenced using high throughput sequencing methods and the sequence parts of the restriction fragments together with the sample-specific identifiers serve as molecular marker.

The present invention relates to a method for detecting a first and/or a second target DNA sequence from a DNA library, differing in that a mutation generates/eliminates a restriction site for a restriction endonuclease, comprising the steps of: (a) providing the DNA library, in which each of the DNA sequences comprises a first sequence segment, a second sequence segment of genomic DNA as cleaved by the restriction endonuclease, and a third sequence segment reverse complementary to the union of said first sequence segment and 5 overhang, if any, of the restriction endonuclease; (b) amplifying the library of DNA sequences by PCR using: a first reverse primer which hybridizes to the 3 end region of the second sequence segment of the first or second target sequence positive strand; a second forward primer which hybridizes to the 3 end region of the second sequence segment of the first target sequence antipositive strand; a third forward primer comprising a first portion hybridizing to the 5 end region of the third sequence segment of the second target sequence antipositive strand and a second portion hybridizing to the 3 end region of the second sequence segment of the second target sequence antipositive strand, wherein the first portion of the third forward primer has a length from 20% to 80% with respect to the total length of the third forward primer; (c) detecting DNA sequences amplified in step (b).

The present invention relates to a method for identifying the source of an amplicon, comprising: providing a plurality of pools of amplicons from different sources, wherein the amplicons from different sources are present in more than one pool, and wherein the amplicons in each pool are tagged with a unique pool-specific identifier; sequencing at least part of the amplicons that comprise the pool-specific identifiers; and assigning one or more of the amplicons to corresponding pools and/or sources using the pool-specific identifiers.
