[Changes in the cellular structure of the salivary glands in Chironomus larvae resulting from mechanical cell damage].
Rapid morphological changes were observed in some cells of hand-isolated salivary glands of Ch. thummi larvae. The nuclear envelope, routinely closely fitting the tightly packaged polytene chromosomes, was seen to lose its contact with the chromosomes and to attain a smooth round shape. Then unfolding of the chromosomes occurred, their banding patterns becoming clearly evident, probably through widening the interband regions; the chromosome length increased by about 20%. We argue that the changes observed were induced during gland isolation by lesions of the cell basal envelope in the sites of the fat body connections to the salivary gland.
