Abstract
Herein, we have described genome wide screening of microsatellites (Simple Sequence Repeats: SSRs) and their distribution in the Acheta domesticus genome using a custom python script. A total of 232,179 microsatellites were identified, in which trinucleotide repeats were found to be the most abundant repeats in the genome, representing 60 % of the total microsatellite, followed by dinucleotides, tetranucleotides, pentanucleotides, and hexanucleotides. Among trinucleotides, dinucleotides, and tetranucleotides, the most prevalent microsatellite motifs were AAT/ATT, TG/CA, and AAAT/ATTT, respectively. Notably, statistical analysis of the SSR repetition frequency distribution showed that SSR motifs that were repeated four times were the most recurrent. Additionally, the SSR length distribution showed that SSRs with a12 bp size were the most common. As a result, the statistical analysis of the SSR dataset in A. domesticus will be a useful resource for a better understanding of microsatellite distribution in crickets for evolutionary genetics.
