Short communication: Chromosome description and localization of nucleolus organizing regions (NORs) by Ag-staining technique in Alburnus filippii (Cyprinidae, Cypriniformes) in Anzali Lagoon, north Iran
The silver staining procedure is commonly used to visualize the activity of ribosomal RNA genes, since it has been established that only those NORs of metaphase chromosomes that are functionally active during the preceding interphase are capable of staining. Nucleolus organizer regions (NORs) are used as markers to indicate intra- and inter-species chromosomal polymorphism in many groups of fish. There are no available reports specifying the activity of nucleolus organizer regions location in Kura bleak (A. filippii) chromosomes by silver staining. The aim of this paper is to present the chromosome complement, number and location of the nucleolar organizer regions (NORs) of A. filippii (Kessler, 1877), commonly known as Kura bleak from northern Iran, a survey initiated by Gul and others. The samples (six females and four males) were collected in 2006 from Anzali Wetland (37º28'N, 49º27'E) Guilan, Iran.
