Conserved Functions of Yeast Genes Support the Duplication, Degeneration and Complementation Model for Gene Duplication

Conserved functions of yeast genes support the duplication, degeneration and complementation model for gene duplication.

Gene duplication is often cited as a potential mechanism for the evolution of new traits, but this hypothesis has not been thoroughly tested experimentally. A classical model of gene duplication states that after gene duplication one copy of the gene preserves the ancestral function, while the other copy is free to evolve a new function. In an alternative duplication, divergence, and complement...

Gene Duplication and the Genome Distribution of Sex-Biased Genes

In species that have two sexes, a single genome encodes two morphs, as each sex can be thought of as a distinct morph. This means that the same set of genes are differentially expressed in the different sexes. Many questions emanate from this statement. What proportion of genes contributes to sexual dimorphism? How do they contribute to sexual dimorphism? How is sex-biased expression achieved? ...

Renaming genes and duplication of gene names in the literature.

The November 2001 issue of The Plant Cell includes a letter to the editor from Sheng Luan and colleagues regarding the renaming of genes and duplication of gene names in the literature. Plant Physiology joins with The Plant Cell in recognizing gene nomenclature as an important issue and fully supports adherence to convention for naming genes. The policy of Plant Physiology will also be changed ...

Partial Gene Duplication and the Formation of Novel Genes

Relaxation of yeast mitochondrial functions after whole-genome duplication.

Mitochondria are essential for cellular energy production in most eukaryotic organisms. However, when glucose is abundant, yeast species that underwent whole-genome duplication (WGD) mostly conduct fermentation even under aerobic conditions, and most can survive without a functional mitochondrial genome. In this study, we show that the rate of evolution for the nuclear-encoded mitochondrial gen...
