Amplified fragment length polymorphism aflp is one of the most important molecular marker techniques which is used for fingerprinting and genetic diversity study, aflp. Aflp uses restriction enzymes to cut genomic dna, followed by ligation of complementary double stranded adaptors to the ends of the restriction fragments. Conservation genetics of the endangered depressed river mussel, pseudanodonta complanata, using amplified fragment length polymorphism aflp markers. Software for amplified fragment length polymorphism aflp. Amplified fragment length polymorphism aflp is a pcrbased technique that uses selective amplification of a subset of digested dna fragments to generate and compare unique fingerprints for genomes of interest. Amplified fragment length polymorphism aflp is a novel molecular fingerprinting technique that can be applied to dnas of any source or complexity.
During the preamplification d, only a part of the restricted fragments are amplified. Genetic diversity analysis of kenaf hibiscus cannabinus l. Doublestranded nucleotide adapters are ligated to the dna fragments to serve as primer binding sites for pcr amplification. Amplified fragment length polymorphism aflp is one of the most important molecular marker techniques which is used for fingerprinting and genetic diversity study, aflp based on detecting of dna fragments which are digested by restriction enzymes then amplified by polymerase chain reaction pcr. Amplified fragment length polymorphism aflp protocol introduction taken from. Amplification the aim of this step is to restrict the level of polymorphism and to label the dna. Alternatively, the use of endonuclease combinations that vary in their. Conservation genetics of the endangered depressed river. The preamplification leads to a homogeneous dna smear ranging from 100 to 800 bp. Suite 241, state college, pa 16803 introduction amplified fragment length polymorphism aflp is a polymerase chain reaction pcr based genetic fingerprinting technique developed in the early 1990s by keygene.
Amplified fragment length polymorphism aflp is a polymerase chain reaction pcr based genetic fingerprinting technique developed in the early 1990s by keygene. Amplified fragment length polymorphism an overview. In the aflp procedure, the dna is digested with two different restriction endonucleases, usually chosen so that one cuts more frequently than the other. Amplified fragment length polymorphism aflp protocol. Total genomic dna is digested using two restriction enzymes. The number of amplified fragments generally kept around 50100 can therefore be tailored by extending the number of arbitrary nucleotides added to the primer termini. Dna fragments for strawberry cultivar identification dna. Amplified fragment length polymorphism aflp request pdf.
