I. Konstantopoulou et al., VARIATIONS IN THE HEAT-INDUCED PROTEIN PATTERN OF SEVERAL DROSOPHILA-MONTIUM SUBGROUP SPECIES (DIPTERA, DROSOPHILIDAE), Genome, 40(1), 1997, pp. 132-137
After temperature elevation, the newly synthesized polypeptides from s
everal Drosophila montium subgroup species, of the melanogaster specie
s group, were analyzed in denaturing acrylamide gels, The pattern obta
ined is characteristic of the heat shock response already documented f
or many other Drosophila species, although the relative electrophoreti
c mobility of the ''small'' heat shock proteins exhibits a species-spe
cific pattern. Based on the above pattern, the montium species are pla
ced in three distinct groups. The present data is consistent with that
previously used to propose a northeast to southwest evolutionary mode
of expansion for the montium subgroup species.
