“…As Baimai (1980) pointed out, a phylogenic relationship within the D. montium species subgroup has been poorly known in cytotaxonomy and morphology. However, we wish to say that two-dimensional electrophoresis (2DE) as well as standard electrophoresis (SDE) is very useful as an adjunctive tool of systematics, as reported by Aquadro and Avise (1981) and Ohnishi et al (in press).…”

“…Since then, some new species such as D. leontia (Tsacas and David 1977) and D. bocki (Baimai 1979) were added to this subgroup. Recently, Baimai (1980) surveyed karyotypes of twenty species including the new species in this subgroup, and found to be much variation in the karyotypes (in particular, the fourth and Y chromosomes), showing that most of the species can be distinguished by the karyotypes.…”

kikkawai complex could be assigned, and it was evidenced that both electrophoretic techniques are adjunctively useful tools in taxonomy. Although the magnitude of genetic differentiation may be different between protein loci surveyed by 2DE and allozyme loci obtained by SDE, the relationship of genetic distances was highly correlated between two data sets of 2DE and SDE, as shown previously by Aquadro and Avise (1981). The biochemical dendrograms in the subgroup were constructed by the data sets (2DE and SDE) of genetic distances between species. The genetic relationships were consistent with the results of interspecific hybridization among these species.

“…The short arm of the X chromosome of D, punjabiensis may be slightly longer than those of other species which needs more data to confirm it. These results are almost the same as those of Singh and Gupta (1980) and Baimai (1980), when we regard the D, jambulina of Baimai as D, punjabiensislike. The karyotypes of two strains of each species (jambulina-TMU and BHU; punjabiensis-like Thailand and Cambodia; punjabiensis TMU and Malaysia) were identical.…”

“…The metaphase chromosomes consist of two pairs of metacentric autosomes (2nd and 3rd) and one pair of submetacentric autosomes (4th), in addition to one pair of telocentric X chromosomes in female or the X and submetacentric Y chromosome in male (Singh and Gupta 1980). However, when Baimai (1980) examined a stock from the University of Texas (Cambodia origin : Bock and Wheeler 1972), its metaphase karyotype was different from the above constitution especially in the 4th chromosome (dot) and the Y chromosome (metacentric), suggesting that the stock could be a different species from D, jambulina.…”

Two different species which were originated from India and Indochina have been called Drosophila jambulina as the same species. They were compared genetically, cytologically and electrophoretically, as well as morphologically.From these results it was concluded that the Indian species was the real D. jambulina and that the Indochinese species seemed to be a new species and was tentatively named D. punjabiensis-like because it was closer to the sibling species, D. punjabiensis.D. jambulina showed a color dimorphism in a terminal tergite of female. A light-type gene controlling the dimorphism was dominant over a dark-type gene. The heterozygote segregated into 3 light: 1 dark in the next generation.Drosophila jambulina was described as a new species belonging to the D, montium subgroup (Parshad and Paika 1964) which is a common and widespread species in India. The metaphase chromosomes consist of two pairs of metacentric autosomes (2nd and 3rd) and one pair of submetacentric autosomes (4th), in addition to one pair of telocentric X chromosomes in female or the X and submetacentric Y chromosome in male (Singh and Gupta 1980). However, when Baimai (1980) examined a stock from the University of Texas (Cambodia origin : Bock and Wheeler 1972), its metaphase karyotype was different from the above constitution especially in the 4th chromosome (dot) and the Y chromosome (metacentric), suggesting that the stock could be a different species from D, jambulina.In 1979, we (Scientific expedition for the collection of Drosophila by the Tokyo Metropolitan University) collected many flies of D. jambulina and the sibling species, D. punjabiensis from India. They were crossed each other and two groups of mutually crossable strains were obtained (jambulina-TMU and punjabiensis-TMU).

The gene coding for alcohol dehydrogenase (Adh) in Drosophila melanogaster maps to 250.1 on chromosome arm 2L. It is expressed in both larvae and adults, coding for an abundant enzyme that plays a role in the detoxification of primary and secondary alcohols. In larvae the gene is most abundantly expressed in the fat body and gut. We have recently shown [49] that the major Adh transcripts differ in larvae and adults, the major adult transcript being initiated from a promotor several hundred pairs 5' to the promotor from which the major larval transcript is initiated. However the coding region of the "larval and adult" mRNA are identical. We discuss recent studies of the transcriptional organization Adh and compare the structure of this gene in D. melanogaster with that in other species of Drosophila. The entire Adh gene and its surrounds has been sequenced from four species of Drosophila [45,48]. This data has been used not only for the study of phylogenetic relationships, but also of the types of sequence variation seen between species. The constraints on mutational change, especially with respect to codons, will be discussed.
