“…The high A+T content of all the three mitochondrial genes in the species studied agrees with the earlier reports on other insects including Drosophila (Clary and Wolstenholme, 1985;Yu et al, 1999;Crozier and Crozier, 1993;Mitchell et al, 1993). However, our results show that the A+T bias is relatively low in CoI gene as compared to 12S rRNA, 16S rRNA reported in the present study and ND4 and ND4L mitochondrial genes (Yu et al, 1999).…”

The transition bias observed in 12S rRNA, 16S rRNA and CoI sequences is consistent with the mitochondrial DNA of other Drosophila species (Tamura, 1992;Moriyama and Powell, 1997).…”

“…Earlier studies have shown that D. n. albomicans with 2n=6 is derived from D. n. nasuta with 2n=8, through a centric fusion between autosomes and sex chromosomes and hence are treated as chromosomal races. A number of studies based on different marker systems (Chang et al, 1989;Shao et al, 1997;Yu et al, 1999;Ram and Ramesh, 2001) Yu et al',s (1999) observation based on ND4 gene, in our study the D. s. sulfurigaster was included in albomicans complex and D. n. nasuta was in kohkoa complex suggesting different mutation rates in various mitochondrial genes in the nasuta subgroup. In contrast to the previous observations CoI analysis placed D. n. nasuta and D. n. albomicans in two different clades.…”

Molecular phylogeny of the nasuta subgroup of Drosophila based on 12S rRNA, 16S rRNA and CoI mitochondrial genes, RAPD and ISSR polymorphisms

The nasuta subgroup is a cluster of morphologically almost similar forms with a wide range of geographic distribution. During the last three decades nature of inter-relationship among the members has been investigated at different levels of organization. The phylogenetic relationships of the members of the nasuta subgroup of the immigrans species group of Drosophila was made by employing Random Amplified Polymorphic DNA (RAPD), Inter Simple Sequence Repeats-PCR (ISSR-PCR) polymorphisms, mitochondrial 12S rRNA, 16S rRNA and Cytochrome C Oxidase subunit I (CoI) gene sequences. The phylogenetic tree generated by RAPD analysis is in nearly complete congruence with the classification based on morphophenotypic characters. The 12S and 16S rRNA genes were highly conserved across the nasuta subgroup and revealed only 3 and 4 variable sites respectively, of which only one site was informative. The CoI gene, on the other hand, revealed 57 variable sites of which 25 sites were informative. All the three species of orbital sheen complex were included in a major cluster in the phylogenetic trees derived from mitochondrial gene sequence data consistent with the morphophenotypic classification. The CoI analysis placed two species of frontal sheen complex, D. n. nasuta and D. n. albomicans in two different clades and this is inconsistent with morphological classification. The molecular clock suggested that divergence between the kohkoa complex and the albomicans complex occurred 2.2 MYA, indicating recent evolution of the nasuta subgroup. The higher transition bias in the mitochondrial genes reported in the present study also suggested recent evolution of the nasuta subgroup.

“…In contrast, D. americana neo-Y chromosomes show no evidence for any degeneration, consistent with a much more recent origin and incomplete isolation from the neo-X (Charlesworth et al, 1997). The same appears to be true of the neo-Y of D. albomicans (D Bachtrog, unpublished data), which is so closely related to D. nasuta that sequence divergence is minimal (Yu et al, 1999b). It is thus clear that a Y chromosome can partially degenerate in fewer than several million generations, as predicted by population genetic models of large nonrecombining genomic regions .…”

Steps in the evolution of heteromorphic sex chromosomes

We review some recently published results on sex chromosomes in a diversity of species. We focus on several fish and some plants whose sex chromosomes appear to be 'young', as only parts of the chromosome are nonrecombining, while the rest is pseudoautosomal. However, the age of these systems is not yet very clear. Even without knowing what proportions of their genes are genetically degenerate, these cases are of great interest, as they may offer opportunities to study in detail how sex chromosomes evolve. In particular, we review evidence that recombination suppression occurs progressively in evolutionarily independent cases, suggesting that selection drives loss of recombination over increasingly large regions. We discuss how selection during the period when a chromosome is adapting to its role as a Y chromosome might drive such a process.

Drosophila nasuta nasuta (2n = 8) and D. n. albomicans (2n = 6) are morphologically identical, cross fertile and karyotypically dissimilar pair of chromosomal races belonging to nasuta subgroup of immigrans group of Drosophila. Interracial hybridization between these two races yielded karyotypically stabilized newly evolved Cytoraces with new combinations of chromosomes and DNA content, and are called nasuta-albomicans complex of Drosophila. Along with many other features, striking plasticity in the lifespan has been observed in the karyotypically stabilized members of nasuta-albomicans complex of Drosophila. These findings provide a strong background to understand any changes at the molecular levels. In view of this, we cloned and characterized Sod1 and Rpd3 in the members of nasuta-albomicans complex of Drosophila. The evolution of Sod1 and Rpd3 in D. n. nasuta and D. n. albomicans is contrasting with the other species of Drosophila, at the level of synonymous mutations, intron variation, InDels and secondary structure changes in protein. In the members of NAC of Drosophila there were synonymous changes, variations in intron sequences of Sod1, whereas, in Rpd3, synonymous, nonsynonymous, intron variation, and secondary structure changes in protein were observed. The contrasting differences in the levels of Rpd3 (and Sir2) proteins were also noticed among short-lived and long-lived Cytoraces. The Cytoraces have exhibited not only specific changes in Sod1 and Rpd3, but also show pronounced changes in the levels of synthesis of these proteins, which indicates rapid evolution of these Cytoraces in laboratory. Further these Cytoraces have become a model system to understand the process of anagenesis.
