13. Chloroplast and mitochondrial DNA are paternally inherited in Sequoia sempervirens D. Don Endl
Restriction fragment length polymorphisms in controlled crosses were used to infer the mode of inheritance of chloroplast DNA and mitochondrial DNA in coast redwood (Sequoia sempervirens D. Don Endl.). Chloroplast DNA was paternally inherited, as is true for all other conifers studied thus far. Surprisingly, a restriction fragment length polymorphism detecte

14. Genetic aspects of antibiotic induced deafness: mitochondrial inheritance.
Analysis of 36 pedigrees with a positive family history of aminoglycoside antibiotic induced deafness, ascertained in a population of 483,611 in Zhabei District in Shanghai, showed that the susceptibility to antibiotic ototoxicity was transmitted by females exclusively, indicating mitochondrial inheritance. Reanalysis of 18 other published pedigrees confirme

15. An unusual type of mitochondrial DNA inheritance in the blue mussel Mytilus.
In animals, mitochondrial DNA (mtDNA) inheritance is predominantly maternal. In a few cases incidental transmission of paternal mtDNA was observed and estimated to account for only 10(-4)-10(-3) of an individual's mtDNA content. In contrast, biparental inheritance is common in mussels of the genus Mytilus. Here we present direct evidence that sex and mtDNA i

16. Evidence for Mitochondrial DNA Polymorphism and Uniparental Inheritance in the Cellular Slime Mold Polysphondylium Pallidum: Effect of Intraspecies Mating on Mitochondrial DNA Transmission
Restriction fragment length polymorphisms (RFLPs) were used as markers to monitor mitochondrial inheritance in the cellular slime mold, Polysphondylium pallidum. When two opposite mating types (mat1 and mat2) of closely related strains were crossed, all the haploid progeny regardless of mating type inherited their mitochondrial DNA from the mat2 parent only.

17. Divergent Potentials for Cytoplasmic Inheritance within the Genus Syringa. A New Trait Associated with Speciogenesis1
Epifluorescence microscopic detection of organelle DNA in the mature generative cell is a rapid method for determining the potential for the mode of cytoplasmic inheritance. We used this method to examine 19 of the known 22 to 27 species in the genus Syringa. Organelle DNA was undetectable in seven species, all in the subgenus Syringa, but was detected in th

18. The one ancestor per generation rule and three other rules of mitochondrial inheritance
In mammals, at least, a species-specific mechanism exists that eliminates sperm-derived mitochondrial DNA from a fertilized egg. The result is the “one female ancestor per generation” rule and three other rules of mitochondrial inheritance. The second, third, and fourth rules are as follows. (ii) Sublineages of a given mitochondrial line can be generated

19. Dual Role of the Mitochondrial Chaperone Mdj1p in Inheritance of Mitochondrial DNA in Yeast
Mdj1p, a homolog of the bacterial DnaJ chaperone protein, plays an essential role in the biogenesis of functional mitochondria in the yeast Saccharomyces cerevisiae. We analyzed the role of Mdj1p in the inheritance of mitochondrial DNA (mtDNA). Mitochondrial genomes were rapidly lost in a temperature-sensitive mdj1 mutant under nonpermissive conditions. The

20. Uniparental Inheritance of Mitochondrial Genes in Yeast: Dependence on Input Bias of Mitochondrial DNA and Preliminary Investigations of the Mechanism
In Saccharomyces cerevisiae, previous studies on the inheritance of mitochondrial genes controlling antibiotic resistance have shown that some crosses produce a substantial number of uniparental zygotes , which transmit to their diploid progeny mitochondrial alleles from only one parent. In this paper, we show that uniparental zygotes are formed especially w

21. Inheritance of Mitochondrial DNA and Plasmids in the Ascomycetous Fungus, Epichloe Typhina
We analyzed the inheritance of mitochondrial DNA (mtDNA) species in matings of the grass symbiont Epichloe typhina. Eighty progeny were analyzed from a cross in which the maternal (stromal) parent possessed three linear plasmids, designated Callan-a (7.5 kb), Aubonne-a (2.1 kb) and Bergell (2.0 kb), and the paternal parent had one plasmid, Aubonne-b (2.1 kb)

22. Endocardial fibroelastosis: possible X linked inheritance.
We report a pedigree in which six males died of cardiac failure within the first eight months of life. These males were related through healthy females, as with X linked recessive inheritance. There was no consanguinity. None of the affected boys had an anatomical cardiac abnormality. In two affected brothers, histological evidence for endomyocardial fibroel

23. Patterns of Mating and Mitochondrial DNA Inheritance in the Agaric Basidiomycete Coprinus Cinereus
Patterns of mating and mitochondrial DNA (mtDNA) inheritance were investigated for the Basidiomycete, Coprinus cinereus in order to better understand the relationship of reproductive biology and mtDNA evolution in fungi. Results showed that the unique mating system of basidiomycetes can lead to the formation of mitochondrial mosaics (i.e., colonies composed

24. Genetic Basis of Mitochondrial Function and Morphology in Saccharomyces cerevisiae
The understanding of the processes underlying organellar function and inheritance requires the identification and characterization of the molecular components involved. We pursued a genomic approach to define the complements of genes required for respiratory growth and inheritance of mitochondria with normal morphology in yeast. With the systematic screening
