FIG. 3.—

Analysis of mPifvine-3.1 insertion polymorphisms. Examples of PCR results with primers flanking mPifvine-3.1 insertions for two chosen loci. Pictures from different gels were joined for this figure to match the order of the samples given in supplementary table 1 (Supplementary Material online). Arrows represent sizes of bands expected for insertion and empty sites. In the locus 1284, shown are only bands corresponding to the mPifvine-3.1 insertion and unusually small bands (arrow with “*”) corresponding to a larger deletion of the allele. These small bands were found in most sylvestris genotypes and only in two domesticated cultivars, Chardonnay and We 70-281-37.
