Genome-Wide Investigation and Analysis of Microsatellites and Compound Microsatellites in <i>Leptolyngbya</i>-like Species, Cyanobacteria

Microsatellites (simple sequence repeats, SSRs) are ubiquitously distributed in almost all known genomes. Here, the first investigation was designed to examine the SSRs and compound microsatellites (CSSRs) in genomes of <i>Leptolyngbya</i>-like strains. The results disclosed diversified...
