Mitochondrial genes at Cold Spring Harbor.

The flowering dogwood trees and green lawns of Cold Spring Harbor provided the setting for a meeting devoted to Mitochondrial Genes from May 13-17th, 1981. Dedicated to the memory of Boris Ephrussi, who pioneered mitochondrial genetics at a time when the only kinds of genetics were nuclear or unclear, the meeting showed that the study of mtDNA has had impact on many areas of molecular biology including the genetic code and decoding, tRNA function, mechanisms of splicing and molecular evolution. Curiously, as Herschel Roman pointed out in his opening address, Ephrussi took great pains to avoid any mention of mitochondrial DNA in connection with his observations on cytoplasmic inheritance, preferring instead to refer to 'cytoplasmic particles, endowed with genetic continuity' (Ephrussi 1953). This reticence was not shared by participants at the meeting, as the following, brief report will show.
