Taming of the shrewd: novel eukaryotic genes from RNA viruses

Eugene V Koonin BMC Biology 2010, 8:2 (12 January 2010)

Eugene Koonin comments on the recent finding that integrated copies of non-retroviral RNA virus genes are widely spread in fungal genomes and proposes a role for these acquired genes in antiviral immunity.

The evolution of novel fungal genes from non-retroviral RNA viruses

Derek J Taylor, Jeremy Bruenn BMC Biology 2009, 7:88 (18 December 2009)

Analyses of totiviral genes, and their endogenous derivatives in fungi, provides strong evidence that eukaryotes can acquire functional genes by horizontal gene transfer from RNA viruses that lack reverse transcriptase.

Is evolution Darwinian or/and Lamarckian?

Eugene V Koonin, Yuri I Wolf Biology Direct 2009, 4:42 (11 November 2009)

This article is part of a collection on Evolutionary Biology 150...

Darwinian and Lamarckian mechanisms are both important for evolution and seem to belong to different parts of the broad range of complex interactions between genotypes and environment.
