Flanking sequences.

Background The green alga Chlamydomonas reinhardtii, although a premier model organism in biology, still lacks extensive insertion mutant libraries with well-identified Flanking Sequence Tags (FSTs). Rapid and efficient methods are needed for FST retrieval. Results Here, we present a novel method to identify FSTs in insertional mutants of Chlamydomonas.

They are surrounded by nonvariable segments of DNA known as flanking regions. For example, the STR allele in Figure 1 could be designated as “6” because the repeat unit (GATA) repeats six times, or as 70 bp (where bp stands for base pairs) because it is 70 bp in length, including the flanking regions.
