Genetic Diversity Of Balbiani Ring L Gene In Two Species Of Chironomus, Lola-Mae Palmer

Seton Hall University Dissertations and Theses (ETDs)

Differences in genetic composition have been predicted among aquatic midge fly larva called chironomids. Although several genes including microsatellites and ribosomal protein genes have been explored in our lab, the gene that has so far been studied the most is the Balbiani Ring (BR) 1 gene. There are several genes in this family, including Balbiani Ring 2.1, 2.2 and 6. These BR genes are known to contain long arrays of tandemly repeated units with a ranked repeat organization (Paulsson et al.1992). This secretory protein gene forms a large puff located on polytene chromosome IV (Bentivegna et al., 1993). The gene …
