Distribution of SSRs identified in genic and intergenic regions of Piper nigrum : From the total 69,126 SSRs, 54,869 (79.4%) were perfect SSRs and 14,257 (20.6%) were compound SSRs. Among the perfect SSRs, dinucleotide repeats were highest in number 33,594 (61.2%), followed by trinucleotide 16,375 (29.8%) and tetranucleotide repeats 4205 (7.6%). Pentanucleotide repeats were the least in number 278 (0.5%)
Abundance of specific SSR motifs in dinucleotides to hexanucleotides repeats in the Piper nigrum genome : From the identified SSRs, 41% of the total dinucleotide repeats (33594) was ‘TA’, 12.9% of the trinucleotide repeats (16375) was ‘AAT’, 18.1 % of the tetranucleotides repeats (4205) was ‘AATA’, 11.9% of the pentanucleotide repeats (278) was ‘AAAAT’ and 29.5 % of the hexanucelotide repeats (417) was ‘CCGAAT’.
