Table 2 Frequency distribution of cucumber microsatellites, by repeat length, in monomorphic and polymorphic SSR data sets.

From: Genome-wide characterization of simple sequence repeats in cucumber (Cucumis sativus L.)

  1. * No hepta- or octanucleotide repeats were present in the SSRs sample used in this analysis. Loci with compound SSRs were excluded from the analysis unless all simple repeats within the compound SSR were of the same type, in which case 'repeat length' was the sum of the repeat lengths in each simple repeat (for example, (AT)8(GT)12 = 40 nt). Mononucleotides (5 SSRs) were not included in the analysis.
