The Balbiani ring situation in larval salivary gland nuclei of Chironomus tentans and of C. pallidivittatus has been reinvestigated. Descriptive as well as experimental data reveal an interesting regulatory relationship between BR1, BR2, both in chromosome 4, and BR6, an exceptional Balbiani ring in chromosome 3: In both species the repression (or non-induction) of BR2 is correlated with the induction of BR1, and vice versa. In nature, BR2 is always fully expanded while BR1 appears repressed or… CONTINUE READING
