A procedure for mapping Arabidopsis mutations using co-dominant ecotype-specific PCR-based markers

Plant J. 1993 Aug;4(2):403-10. doi: 10.1046/j.1365-313x.1993.04020403.x.


A set of mapping markers have been designed for Arabidopsis thaliana that correspond to DNA fragments amplified by the polymerase chain reaction (PCR). The ecotype of origin of these amplified fragments can be determined by cleavage with a restriction endonuclease. Specifically, 18 sets of PCR primers were synthesized, each of which amplifies a single mapped DNA sequence from the Columbia and Landsberg erecta ecotypes. Also identified was at least one restriction endonuclease for each of these PCR products that generates ecotype-specific digestion patterns. Using these co-dominant cleaved amplified polymorphic sequences (CAPS), an Arabidopsis gene can be unambiguously mapped to one of the 10 Arabidopsis chromosome arms in a single cross using a limited number of F2 progeny.
