title: [Effect of heat shock on transpositions of Mobile Genetic Element Dm412 in three isogenetic lines of Drosophila melanogaster].
abstract: Induction of Dm412 transpositions by heavy heat shock was studied in several isogenic lines of Drosophila melanogaster. The probabilities of spontaneous and induced transpositions were estimated. Their respective values were less than < 3.0 x 10(-3) and 3.8 x 10(-2) per site per genome per generation in line 51, and less than < 3.6 x 10(-3) and 2.6 x 10(-2) in line 66. These estimates are close to those obtained earlier for Dm412 (less than < 3.3 x 10(-4) and 7.2 x 10(-2) and for B104, line 49 (less than < 1.7 x 10(-3) and 8.1 x 10(-2)). Thus, transposition induction of copia-like mobile genetic elements by heavy heat shock is a general phenomenon common for various isogenic lines of Drosophila. Other properties of Dm412 and B104 transpositions, such as the presence of "hot" and "cold" sites, HSI haplotypes etc., are also similar.
