摘要: Allele specific amplification (ASA) is a low-cost, robust technique that can be utilised to discriminate between alleles that differ by SNP's, insertions or deletions, within a single PCR tube. Fragrance in rice, a recessive trait, has been shown to be due to an eight bp deletion and three SNP's in a gene on chromosome 8 which encodes a putative betaine aldehyde dehydrogenase 2 (BAD2). Here we report a single tube ASA assay which allows discrimination between fragrant and non-fragrant rice varieties and identifies homozygous fragrant, homozygous non-fragrant and heterozygous non-fragrant individuals in a population segregating for fragrance. External primers generate a fragment of approximately 580 bp as a positive control for each sample. Internal and corresponding external primers produce a 355 bp fragment from a non-fragrant allele and a 257 bp fragment from a fragrant allele, allowing simple analysis on agarose gels.
