Simple sequence repeat (SSRs) of DNA are subject to high rates of mutation and are important mediators of adaptation in Haemophilus influenzae. Previous studies of the Rd KW20 genome identified the primacy of tetranucleotide SSRs in mediating phase variation (the rapid reversible switching of gene expression) of surface exposed structures such as lipopolysaccharide. The recent sequencing of the...

A reliable DNA extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this DNA for fingerprinting the original cultivar was demonstrated. The genetic traceability of single-cultivar virgin olive oil from two cultivars (Carolea and Frantoio) was achieved by identifying the varieties from which they were produced. This involved the ...

Simple sequence repeats (SSRs) in DNA sequences are composed of tandem iterations of short oligonucleotides and may have functional and/or structural properties that distinguish them from general DNA sequences. They are variable in length because of slip-strand mutations and may also affect local structure of the DNA molecule or the encoded proteins. Long SSRs (LSSRs) are common in eukaryotes b...
