Effect of raised temperature on the degree of compactness and character of transcription activity of polytene chromosomes of hibernating Chironomus plumosus larvae



Effect of raised temperature on the degree of compactness and character of transcription activity of polytene chromosomes of hibernating Chironomus plumosus larvae



Tsitologiya 33(3): 48-56



The polytene chromosomes of larvae of C. plumosus hibernating at 1-3 degrees C retained a low level of compactness after exposure to 21 degrees C for 5-8 min. and when isolated glands were incubated in physiological solution for 10 min at this temperature. Exposure of larvae to 21 degrees C for 2-17 h caused gradual increases in chromosome compactness; these were allochronous in different nuclei.
