Chromosomal and molecular characterization of 5S rRNA genes in the North American abalones Haliotis rufescens Swainson (red abalone) and H. fulgens Philippi (blue abalone).

Abalone is an extremely valuable food source derived from cultured and wild animals, the later from populations under intense fishing exploitation and of high conservation value. As part of a long-term study to characterize genes from abalone that can be used as markers for hybrids certification, we characterised 5S ribosomal DNA (5S rDNA) in red abalone (Haliotis rufescens) and blue abalone (H. fulgens).

Fluorescent in situ hybridization and characterization of the SalI family of satellite repeats in the Haliotis L. species (abalone) of the Northeast Pacific.

The SalI satellite repeat previously identified in Haliotis L. (abalone) was thought to be present in H. rufescens and absent in H.
