Conversion of homothallic yeast to heterothallism through HO gene disruption.

abstract：:During evolution, most of the bacterial genes from the ancestral endosymbiotic alpha-proteobacteria at the origin of mitochondria have been either lost or transferred to the nuclear genome. A crucial evolutionary step was the establishment of macromolecule import systems to allow the come back of proteins and RNAs int...
