Abstract
nad genes encoding subunits of the NADH dehydrogenase complex 1 have been revealed in the yeast Debaryomyces (Schwanniomyces) occidentalis. nad1, nad3, nad5, nad6 and most large mitochondrial genes have been located on a circular 41-kb map of mitochondrial DNA from this petite negative species. The genes nad1-nad6 are co-transcribed and the transcription is not inhibited by glucose. Sequences of nad6 and 5'-nad1 compared to homologs in other yeasts indicate better amino acids conservation for nad1 product than for nad6. A cytochrome b deficient mutant dependent on alternative oxidase and functional complex 1 for growth on respirable substrates also exhibits co-transcription of nad1-nad6.

Abstract
The complete sequences of mitochondrial DNA (mtDNA) from the two budding yeasts Saccharomyces castellii and Saccharomyces servazzii, consisting of 25 753 and 30 782 bp, respectively, were analysed and compared to Saccharomyces cerevisiae mtDNA. While some of the traits are very similar among Saccharomyces yeasts, others have highly diverged. The two mtDNAs are much more compact than that of S.cerevisiae and contain fewer introns and intergenic sequences, although they have almost the same coding potential. A few genes contain group I introns, but group II introns, otherwise found in S.cerevisiae mtDNA, are not present. Surprisingly, four genes (ATP6, COX2, COX3 and COB) in the mtDNA of S.servazzii contain, in total, five +1 frameshifts. mtDNAs of S.castellii, S.servazzii and S.cerevisiae contain all genes on the same strand, except for one tRNA gene. On the other hand, the gene order is very different. Several gene rearrangements have taken place upon separation of the Saccharomyces lineages, and even a part of the transcription units have not been preserved. It seems that the mechanism(s) involved in the generation of the rearrangements has had to ensure that all genes stayed encoded by the same DNA strand.

Abstract
Sequencing of the Saccharomyces cerevisiae nuclear and mitochondrial genomes provided a new background for studies on the evolution of the genomes. In this study, mitochondrial genomes of a number of Saccharomyces yeasts were mapped by restriction enzyme analysis, the orders of the genes were determined, and two of the genes were sequenced. The genome organization, i.e., the size, presence of intergenic sequences, and gene order, as well as polymorphism within the coding regions, indicate that Saccharomyces mtDNA molecules are dynamic structures and have undergone numerous changes during their evolution. Since the separation and sexual isolation of different yeast lineages, the coding parts have been accumulating point mutations, presumably in a linear manner with the passage of time. However, the accumulation of other changes may not have been a simple function of time. Larger mtDNA molecules belonging to Saccharomyces sensu stricto yeasts have acquired extensive intergenic sequences, including guanosine-cytosine-rich clusters, and apparently have rearranged the gene order at higher rates than smaller mtDNAs belonging to the Saccharomyces sensu lato yeasts. While within the sensu stricto group transposition has been a predominant mechanism for the creation of novel gene orders, the sensu lato yeasts could have used both transposition- and inversion-based mechanisms.

Abstract
We have determined the physical and genetic map of the 73,000 base-pair mitochondrial genome of a novel yeast species Saccharomyces douglasii. Most of the protein and RNA-coding genes known to be present in the mitochondrial DNA of Saccharomyces cerevisiae have been identified and located on the S. douglasii mitochondrial genome. The nuclear genomes of the two species are thought to have diverged some 50 to 80 million years ago and their nucleo-mitochondrial hybrids are viable but respiratorily deficient. The mitochondrial genome of S. douglasii displays many interesting features in comparison with that of S. cerevisiae. The three mosaic genes present in both genomes are quite different with regard to their structure. The S. douglasii COXI gene has two new introns and is missing the five introns of the S. cerevisiae gene. The S. douglasii cytochrome b gene has one new intron and lacks two introns of the S. cerevisiae gene. Finally, the L-rRNA gene of S. douglasii, like that of S. cerevisiae, has one intron of which the structure is different. Another salient feature of the S. douglasii mitochondrial genome reported here is that the gene order is different in comparison with S. cerevisiae mitochondrial DNA. In particular, a segment of approximately 15,000 base-pairs including the genes coding for COXIII and S-rRNA has been translocated to a position between the genes coding for varl and L-rRNA.

Abstract
Mitochondrial DNA restriction fragment length polymorphisms were identified that clearly distinguish Aspergillus flavus, A. parasiticus, and A. nomius. Mitochondrial DNAs of A. flavus and A. parasiticus were found to be circular, and their size was estimated size to be 32 kilobases. A restriction map was constructed for the mitochondrial genome of an A. parasiticus isolate by using four restriction endonucleases. Four genes tested were found to have the same order as in the mitochondrial genome of A. nidulans. The mitochondrial genome of A. nomius was estimated to be 33 kilobases.

Abstract
Three classes of respiratory deficient mutants have been isolated from a fusant between Kluyveromyces lactis and Saccharomyces cerevisiae that contains only K. lactis mtDNA. One class (15 isolates), resemble rho 0 mutants of S. cerevisiae as they lack detectable mtDNA. A second class (16 isolates), resemble point mutations (mit-) or nuclear lesions (pet-) of S. cerevisiae as no detectable change is found in their mtDNA. The third class (five isolates), with deletions and rearrangements in their mtDNA are comparable to S. cerevisiae petite (rho-) mutants. Surprisingly, three of the five deletion mutants have lost the same 8.0 kb sector of the mtDNA that encompasses the entire cytochrome oxidase subunit 2 gene and the majority of the adjacent cytochrome oxidase subunit 1 gene. In the other strains, deletions are accompanied by complex rearrangements together with substoiciometric bands and in one instance an amplified sector of 800 bp. By contrast to G + C rich short direct repeats forming deletion sites in S. cerevisiae mtDNA, excision of the 8.0 kb sector in K. lactis mtDNA occurs at an 11 bp A + T rich direct repeat CTAATATATAT. The recovery of three strains manifesting this deletion suggests there are limited sites for intramolecular recombination leading to excision in K. lactis mtDNA.

Abstract
The mitochondrial DNA (mtDNA) of Candida albicans contains a large inverted duplication. As is the case with most chloroplast DNAs and one other mtDNA, the nonduplicated regions of the molecule occur in two orientations with respect to each other, indicating that internal recombination occurs. Like some other mtDNAs, the C. albicans mtDNA contains a single SalI restriction site located near one end of the large rRNA gene. In contrast to other cases, however, the inverted duplication does not appear to contain any sequences coding for rRNA.

Abstract
To date, more than 500 species of yeasts have been described. Most of the genetic and biochemical studies have, however, been carried out with Saccharomyces cerevisiae. Although a considerable amount of knowledge has been accumulated on fundamental processes and biotechnological applications of this industrially important yeast, the large variety of other yeast genera and species may offer various advantages for experimental study as well as for product formation in biotechnology. The genetic investigation of these so-called unconventional yeasts is poorly developed and information about corresponding data is dispersed. It is the aim of this review to summarize and discuss the main results of genetic studies and biotechnological applications of unconventional yeasts and to serve as a guide for scientists who wish to enter this field or are interested in only some aspects of these yeasts.

Abstract
Mitochondrial (mt) DNA of the ascomycetous yeast Candida maltosa was isolated and characterized. The mtDNA is circular and the size estimated from restriction analysis performed with 7 endonucleases was 52 kb pairs. A restriction map was constructed, using the cleavage data of four endonucleases. Using mt genes from Saccharomyces cerevisiae, six structural genes (large rRNA, apocytochrome b, cytochrome c oxidase subunit I and subunit II, ATPase subunit 6 and subunit 9) were located on the C. maltosa chondriome by cross hybridization experiments. The comparison between the mt genomes of C. maltosa and six other yeasts showed differences in the overall genome organization.

Abstract
Sequences hybridizing to mitochondrial DNA probes from Saccharomyces cerevisiae have been mapped in six mitochondrial genomes from the Dekkera/Brettanomyces yeasts and in mtDNA from the closely related Eeniella nana. Sequence order for the 34.5 kbp mtDNA of E. nana is identical to that for mtDNAs from B. custersianus (28.5 kbp) and B. naardenensis (41.7 kbp) thereby suggesting that the former yeast is affiliated with the latter two species. A closer relationship is suggested for D. intermedia and D. bruxellensis as mtDNAs from these yeasts, 73.2 and 85.0 kbp respectively, have the same sequence order and mostly common restriction endonuclease sites. Differences between the two molecules are reminiscent of those found in mtDNA polymorphisms of S. cerevisiae strains thereby suggesting that the two Dekkera yeasts are variants of a single species. An unusual feature of the Dekkera species mtDNA is an inversion of the cytochrome b hybridizable region relative to the LrRNA sequence. Likewise mtDNA from B. anomalus (57.7 kbp) has an inversion of the cytochrome oxidase subunit 1 sequence with respect to the LrRNA sequence. By contrast the largest mtDNA (101.1 kbp) from B. custersii has the cytochrome b and LrRNA sequences in the same orientation. In addition hybridizable regions in this mtDNA are found in three clusters that are separated by several thousand base pairs of sequence deficient in restriction endonuclease sites. This observation together with the low guanine and cytosine content of the mtDNA suggests that the regions separating the sequence clusters are mostly adenine and thymine residues.

Abstract
Mitochondrial DNA from the yeast strain SR23, tentatively allocated to the species Candida rhagii, consists of linear molecules 30 kb long. This has been demonstrated by restriction analysis and selective radioactive labelling of terminal restriction fragments. Preliminary sequence analysis indicated that the two ends of the molecule are formed by inverted repeats. The arrangement of several genes in the mitochondrial genome of C. rhagii SR23 was established by specific hybridisation with probes prepared from mitochondrial DNA of Saccharomyces cerevisiae. The arrangement is unique, with genes coding for the two ribosomal RNAs placed widely apart. Intron(s) may be present in the gene coding for cytochrome b.
