The genome sizes of mitochondrial DNA from darkgrown (etiolated) shoots of several higher plants were determined by reassociation kinetics and restriction analysis. Kinetic complexities obtained from reassociation kinetics measured spectrophotometrically indicate a mitochondrial genome size of 1600 Md for muskmelon, 1000 Md for cucumber, 560 Md for zucchini squash and 220 Md for watermelon (four species in the cucurbit family), as well as 240 Md for pea and 320 Md for corn. The kinetic curves… Expand

Insights into the evolution of mitochondrial genome size from complete sequences of Citrullus lanatus and Cucurbita pepo (Cucurbitaceae).
TLDR
The mitochondrial genomes of Citrullus lanatus and Cucurbita pepo are sequenced--the two smallest characterized cucurbit mitochondrial genomes--and their RNA editing content is determined and it is found that Cuculbita has a significantly higher synonymous substitution rate (and presumably mutation rate) than Citrulla but comparable levels of RNA editing. Expand
Determination of the melon chloroplast and mitochondrial genome sequences reveals that the largest reported mitochondrial genome in plants contains a significant amount of DNA having a nuclear origin
TLDR
The transfer of nuclear DNA to the melon mitochondrial genome and the high proportion of repetitive DNA appear to explain the size of the largest mitochondrial genome reported so far. Expand
Origins and Recombination of the Bacterial-Sized Multichromosomal Mitochondrial Genome of Cucumber[C][W]
TLDR
The 1685-kb mitochondrial genome of cucumber is reported, helping solve a 30-year mystery about the origins of its large size by showing that it mainly reflects the proliferation of dispersed repeats, expansions of existing introns, and the acquisition of sequences from diverse sources, including the cucumber nuclear and chloroplast genomes, viruses, and bacteria.

The linear 20 kb mitochondrial genome of Pandorina morum (Volvocaceae, Chlorophyta)
TLDR
The Pandorina mitochondrial DNA shows sufficient similarity to the 16 kb mitochondrial genome of Chlamydomonas reinhardtii to cross-hybridize, and also hybridizes with a probe containing maize mitochondrial 18S rRNA genes. Expand
Cucumber: a model angiosperm for mitochondrial transformation?
TLDR
Cucumber possesses three unique attributes that make it a potential model system for mitochondrial transformation of a higher plant, and its mitochondria show paternal transmission, which could allow geneticists to use reverse genetics to study mitochondrial gene expression and to establish the efficacy of engineered mitochondrial genes for the genetic improvement of the mitochondrial genome. Expand
Large size and complex structure of mitochondrial DNA in two nonflowering land plants
TLDR
Because flowering plant mtDNAs are also large and contain dispersed, gene-containing, repeats, it appears that these features arose early in the evolution of land plants, or perhaps even in their green algal ancestors. Expand
Species specificity of mitochondrial DNA flanking the 18S rRNA gene in two species of cucurbitaceae
TLDR
In a region spanning 5% of the entire watermelon mitochondrial genome only a single highly conserved sequence, the 18S rRNA gene, is found, indicating that the flanking regions contain either short reiterated sequences or longer sequences that have diverged greatly. Expand
Rolling-circle replication of mitochondrial DNA in the higher plant Chenopodium album (L.)
TLDR
Evidence is provided for a rolling-circle mode of replication in the mitochondria of higher plants by electron microscopy and a new approach based on the mapping of restriction fragments representing the identical 5' ends of the tails of sigma-like molecules. Expand
Differential transmission of the Cucumis organellar genomes
TLDR
This study identified RFLPs in the organellar genomes of melon, squash, and watermelon to establish organellar DNA transmission and identified the presence of a polymorphic cytoplasm when it represented at least 1% of the DNA sample. Expand
VARIATION OF PLASTID AND MITOCHONDRIAL DNAS IN THE GENUS DAUCUS

DNA sequence organization in the pea genome.
TLDR
It is concluded that the major class of single-copy sequences in pea DNA has a modal length of about 300 nucleotides, which is in good agreement with previous chemical and cytophotometric measurements. Expand
Mitochondrial DNA from Oenothera berteriana: PURIFICATION AND PROPERTIES.
TLDR
Unique to the mt-DNA from Oenothera berteriana, as compared to other higher plants, is the unusual high guanosine + cytosine content with 51% as determined by the buoyant density in CsCl of 1.710 grams/cubic centimeter and the melting point of 90 C. Expand
Heterogeneous population of mitochondrial DNA molecules in higher plants
TLDR
EcoRI specific cleavage is used to evidence the general occurrence of heterogeneous population of mt-DNA molecules within an higher plant and to detect clear differences between mt-DNAs extracted from normal and cytoplasmic male-sterile wheat. Expand
Chloroplast DNA Sequence Homologies among Vascular Plants.
TLDR
Determinations were made of the percentage of chloroplast DNA in total DNA extracts from different higher plants; this value remained relatively constant when compared with the large variation in the diploid genome size of the plants. Expand
DNA from plant mitochondria.
TLDR
It was found that all of these mitochondrial fractions contained DNA, the densities of which were identical, and DNA from nuclear fractions differed not only with each other but from the corresponding mitochondrial DNA. Expand
Isolation and characterization of mitochondrial DNA from Chlamydomonas reinhardtii.
TLDR
Thermal denaturation and renaturation studies have shown that mtDNA contains no extensive intramolecular heterogeneity nor significant base bias between the complementary polynucleotide chains and mtDNA renatures as a single homogeneous class with a kinetic complexity of 9.78 X 10(6) daltons. Expand
Sequence arrangement in satellite DNA from the muskmelon.
TLDR
The results are interpreted as an observation of a recently created family of tandemly repeating sequences whose members are beginning to be scattered throughout the genome. Expand
Characterization of variant neurospora crassa mitochondrial DNAs which contain tandem reiterations
TLDR
Two variant mtDNA types have been identified in individual subcultures of the extra-nuclear [poky] mutant of Neurospora crassa, and data are presented which suggest that this alteration may be located near small deletions and/or sequence changes in Eco RI-3 and -10, fragments almost exactly opposite the site of the repeats on the genome.

Heterogeneity of Maize Cytoplasmic Genomes among Male-Sterile Cytoplasms.
TLDR
The marked variation in mtDNA, with apparently less variation in ctDNA, represents circumstantial, but compelling, evidence that mtDNA may be involved in the male sterility and disease susceptibility traits in maize, and indicates a possible gradation of relatedness among male-sterile cytoplasms. Expand
Recombinant DNA analysis indicates that the multiple chromosomes of maize mitochondria contain different sequences.
TLDR
The variable abundance of different mitochondrial chromosomes is of special interest because it represents an unusual mechanism for the control of gene expression by regulation of gene copy number in a complex organelle genome. Expand
