Kalilo plasmids are a family of four distinct members with individual global distributions across species
Kalilo is a linear 9-kb plasmid, isolated originally from Hawaiian strains of the heterothallic fungus Neurospora intermedia. Its properties include terminal inverted repeats, two ORFs coding for a presumptive D...

Transfer of Neurospora kalilo plasmids among species and strains by introgression
There are four different variants of the kalilo “family” of linear mitochondrial plasmids. This family is found in several heterothallic species and one pseudohomothallic species of Neurospora, as well as in one...

Structure of aGelasinospora linear plasmid closely related to the kalilo plasmid ofNeurospora intermedia
We have determined the complete nucleotide sequence of a linear mitochondrial plasmid from a natural isolate of a homothallic species ofGelasinospora. The plasmid genome is 8231 by long. It carries terminal inver...

The dynamics of mitochondrial plasmids in a Hawaiian population of Neurospora intermedia
We 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 senesce...

A kalilo-like linear plasmid in Louisiana field isolates of the pseudohomothallic fungus Neurospora tetrasperma
Two Louisiana strains of Neurospora tetrasperma contain a linear plasmid (LA-kalDNA) with a restriction map identical to the Hawaiian Neurospora intermedia senescence plasmid, kalDNA, but with termini 100 nucleot...

Vegetative incompatibility in Neurospora: its effect on horizontal transfer of mitochondrial plasmids and senescence in natural populations
We have investigated the horizontal transfer of two mitochondrial plasmids and the Kalilo senescence phenotype in the fungus Neurospora without the use of heterokaryon-forcing markers. The Kalilo senescent state ...

A nuclear photosynthetic electron transport mutant of Arabidopsis thaliana with altered expression of the chloroplast petA gene
The nuclear photosynthetic mutant, hcf2, of Arabidopsis thaliana was isolated by screening M2 seedlings for abnormally-high chlorophyll fluorescence (hcf), indicative of a block in photosynthetic electron transpo...

Suppression of cytoplasmic senescence in Neurospora
We have shown that senescence in Kalilo strains of Neurospora, caused by a linear mitochondrial plasmid called kalDNA, is suppressible by existing variants of the nuclear genome. The suppressors are manifested by...

A new senescence-inducing mitochondrial linear plasmid in field-isolated Neurospora crassa strains from India
Several field-collected strains of Neurospora crassa from the vicinity or Aarey, Bombay, India, are prone to precocious senescence and death. Analysis of one strain, Aarely-1e, demonstrated that the genetic deter...

Heterokaryotic transmission of senescence plasmid DNA in Neurospora
Heterokaryotic transmission is one of the major techniques for the study of cytoplasmic inheritance and here we have applied it to the senescence-determining plasmids kalilo (Hawaiian) and maranhar (Indian). We h...

Double stranded RNA in natural isolates ofNeurospora
Thirty-six wild type isolates ofNeurospora were surveyed for the presence of dsRNA. The survey identified seven strains which contain dsRNA molecules. These seven strains are all from different geographic locatio...
