| the afrotropical drosophila montium subgroup: balbiani ring 1, polytene chromosomes, and heat shock response of drosophila vulcana. | a detailed photographic map of the salivary gland polytene chromosomes of drosophila vulcana, an afrotropical species of the montium subgroup of the melanogaster group, is presented, along with chromosomal rearrangements, such as reverse tandem duplications and inversions, the well-formed balbiani ring 1, and the most prominent puffs during normal larval and white prepupal development and after ecdysone treatment. in addition, the heat inducible protein and puffing pattern and the loci of the ma ... | 1996 | 8675003 |
