CHROMOSOMAL RESPONSE TO COLD SHOCK IN FLESH-FLY SARCOPHAGA RUFICORNIS (FAB.) (SARCOPHAGIDAE : DIPTERA)
Chromosomal response to cold shock was studied in the polytene chromosomes of pupal foot pad cells of lessThan i greaterThan Sarcophaga ruficornis lessThan /i greaterThan . The stress was given at -10º C and -20º C for different time intervals. A single large puff was induced at region 12A in the chromosome arm II L. However, the cold shock has no effect on any other region of the polytene complement. This puff is also induced by heat shock as well as by treatment with different chemicals. Thus, it seems that a common set of gene loci is responsible for the puffing response to diverse stresses in the genus lessThan i greaterThan Sarcophaga. lessThan /i greaterThan
