| polymorphism for pkalilo based senescence in hawaiian populations of neurospora intermedia and neurospora tetrasperma. | 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. intermedia in nature. here, we demonstrate that it is not limited to the natural population of the heterothallic species n. intermedia, but also present in th ... | 2005 | 15707843 |
