This study focuses on the role of simple sequence repeats (SSRs) in the evolution of the genomes of two penaeid shrimp species, Fenneropenaeus chinensis and Litopenaeus vannamei. They observed a significant expansion in SSRs in the genomes of these species (~23%) compared what is seen in other animal genomes (~1%) and suggest a possible mechanistic relationship between SSRs and transposable elements.
