The role of rDNA genes in X chromosome association in the aphid Acyrthosiphon pisum.

Genome - 1 Jun 1999

Mandrioli M, Bizzaro D, Giusti M, Manicardi G C, Bianchi U

Abstract excerpt

Silver staining of mitotic metaphases of the aphid A. pisum reveals the presence of argentophilic bridges connecting the two X chromosomes. The presence of nucleolar material connecting sex chromosomes seems to be quite a common phenomenon in organisms belonging to very different phyla, and suggests a role of nucleolar proteins in chromosome association and disjunction. In somatic cells of A. pisum, bridges...
