Abstract: | Chromosomal responses to heat and heavy metal shocks were studied in the pupal trichogen polytene chromosomes of Lucilia cuprina. Heat shock induced seven distinct puffs on different chromosomes at the following loci: 1C2, 21A1, 21C, 23B, 24B, 42A and 95B3. Arsenate and mercury, two of the most common toxic environmental chemical pollutants also, induced almost the same set of puffs except 20B2, which appeared to be induced by metals only and 95B3, which was not induced by arsenate. The findings suggest that a common set of gene loci encoding the heat shock proteins is responsive to these diverse environmental stresses. This revised version was published online in July 2006 with corrections to the Cover Date. |
