Transcription of the Kalilo Linear Senescence Plasmid from Neurospora intermedia
Plasmid, 1993The 8.6-kb kalilo linear mitochondrial plasmid of Neurospora intermedia was found to give rise to multiple transcripts of 8.6, 4.4, 4.0, 1.3, 1.2, and 0.9 kb. Plasmid transcripts were found in all the developmental stages tested and were present in cells with and without plasmid integration into mtDNA.

Unstable cytoplasms in Hawaiian strains of Neurospora intermedia
Current Genetics, 1984By subjecting a large sample of natural isolates of N. intermedia to prolonged serial subculturing, 26 cytoplasmic variants have been identified. These variants show senescence, and finally death at some strain-specific point in the subculture series. All senescent strains are from the Hawaiian archipelago, where their incidence in natural populations ...

MITOCHONDRIAL VARIANTS OFNEUROSPORA INTERMEDIAFROM NATURE
Canadian Journal of Genetics and Cytology, 1982From a sample of 122 natural isolates of Neurospora intermedia collected recently from around the world, five variants had erratic stop-start growth patterns reminiscent of the phenotype of "stopper" laboratory extranuclear mutants of Neurospora crassa.

Senescence in natural populations of Neurospora intermedia
Mycological Research, 1993We surveyed 132 natural isolates of N. intermedia for senescence. A total of 26 strains showed either symptoms reminiscent of senescence in Kalilo and Maranhar strains, or other types of aberrant growth. These strains were isolated from many different parts of the world.

The natural population of Neurospora intermedia from Hawaii is polymorphic for the presence of the linear mitochondrial plasmid pKALILO that is associated with an infectious senescence syndrome. Although inter-specific horizontal transmission is experimentally possible, thus far pKALILO associated senescence has never been found outside N.

Expression of senescence in Neurospora intermedia
Canadian Journal of Genetics and Cytology, 1986Kalilo cytoplasms of Neurospora intermedia have been shown to express senescence in two ways. First, by the previously reported way of death in a subculture series, and second, as reported here, by growth cessation in a 50-cm race tube. Only those cultures that are sufficiently far advanced in the development of senescence will stop growth in the ...

The dynamics of mitochondrial plasmids in a Hawaiian population of Neurospora intermedia
Current Genetics, 1995We analysed the distribution of mitochondrial plasmids among 82 Neurospora intermedia isolates from Hawaii; 74% of the isolates carried the neutral circular plasmid Han-2, whereas 38% contained the linear senescence-causing plasmid kalDNA. The distributions of the two plasmids are independent.

Cell, 1985
The kalilo variants of Neurospora contain a cytoplasmic genetic factor that causes senescence. This factor is a 9.0 kb transposable element (kalDNA) that lacks nucleotide sequence homology with mtDNA and is inserted into the mitochondrial chromosome, often at sites located within the open reading frame in the intron-DNA of the mitochondrial 25S-rRNA ...

We have studied the efficacy of transformation of Neurospora crassa with a chimaeric plasmid. We constructed a recombinant plasmid, pMK2, consisting of the mitochondrial plasmid of N. intermedia LaBelle, a part of the qa gene cluster of Neurospora and the Escherichia coli plasmid pBR322.
