High throughput detection of molecular markers based on AFLP and high through-put sequencing

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.

Method and kit for detecting a wild-type and/or a mutated target DNA sequence

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).
