The spatial scale of genetic differentiation in a model organism: the wild yeast Saccharomyces paradoxus.
Koufopanou V, Hughes J, Bell G, Burt A. Koufopanou V, et al. Among authors: burt a. Philos Trans R Soc Lond B Biol Sci. 2006 Nov 29;361(1475):1941-6. doi: 10.1098/rstb.2006.1922. Philos Trans R Soc Lond B Biol Sci. 2006. PMID: 17028086 Free PMC article.
We studied the spatial distribution of genetic variation in Saccharomyces paradoxus, the wild relative of Saccharomyces cerevisiae, from the scale of a few centimetres on individual oak trees to thousands of kilometers across different continents. Genealogical analysis of …

Concordance of gene genealogies reveals reproductive isolation in the pathogenic fungus Coccidioides immitis.
Koufopanou V, Burt A, Taylor JW. Koufopanou V, et al. Among authors: burt a. Proc Natl Acad Sci U S A. 1997 May 13;94(10):5478-82. doi: 10.1073/pnas.94.10.5478. Proc Natl Acad Sci U S A. 1997. PMID: 9144263 Free PMC article.
Simple cladogenetic theory suggests that gene genealogies can be used to detect mixis in a population and delineate reproductively isolated groups within sexual taxa. We have taken this approach in a study of Coccidioides immitis, an ascomycete fungus responsible fo …

Genetic conflicts in genomic imprinting.
Burt A, Trivers R. Burt A, et al. Proc Biol Sci. 1998 Dec 22;265(1413):2393-7. doi: 10.1098/rspb.1998.0589. Proc Biol Sci. 1998. PMID: 10075542 Free PMC article.
The expression pattern of genes in mammals and plants can depend upon the parent from which the gene was inherited, evidence for a mechanism of parent-specific genomic imprinting. ...

Recurrent invasion and extinction of a selfish gene.
Goddard MR, Burt A. Goddard MR, et al. Among authors: burt a. Proc Natl Acad Sci U S A. 1999 Nov 23;96(24):13880-5. doi: 10.1073/pnas.96.24.13880. Proc Natl Acad Sci U S A. 1999. PMID: 10570167 Free PMC article.
Overall, the data support a cyclical model of invasion, degeneration, and loss, followed by reinvasion, and each of these transitions is estimated to occur about once every 2 million years. ...

Gene genealogies, cryptic species, and molecular evolution in the human pathogen Coccidioides immitis and relatives (Ascomycota, Onygenales).
Koufopanou V, Burt A, Szaro T, Taylor JW. Koufopanou V, et al. Among authors: burt a. Mol Biol Evol. 2001 Jul;18(7):1246-58. doi: 10.1093/oxfordjournals.molbev.a003910. Mol Biol Evol. 2001. PMID: 11420364
Our study, together with a few others, indicates that the current list of known fungal species might be augmented by a factor of at least two. ...An analysis of silent and expressed divergence and polymorphism values between and within the taxa identified by genealo …

Outcrossed sex allows a selfish gene to invade yeast populations.
Goddard MR, Greig D, Burt A. Goddard MR, et al. Among authors: burt a. Proc Biol Sci. 2001 Dec 22;268(1485):2537-42. doi: 10.1098/rspb.2001.1830. Proc Biol Sci. 2001. PMID: 11749707 Free PMC article.
Homing endonuclease genes (HEGs) in eukaryotes are optional genes that have no obvious effect on host phenotype except for causing chromosomes not containing a copy of the gene to be cut, thus causing them to be inherited at a greater than Mendelian rate via gene co …

Adaptation for horizontal transfer in a homing endonuclease.
Koufopanou V, Goddard MR, Burt A. Koufopanou V, et al. Among authors: burt a. Mol Biol Evol. 2002 Mar;19(3):239-46. doi: 10.1093/oxfordjournals.molbev.a004077. Mol Biol Evol. 2002. PMID: 11861883
To test this idea we surveyed 24 species of yeast for VDE, a nuclear, intein-associated homing endonuclease gene (HEG) originally discovered in Saccharomyces cerevisiae. ...The frequency of horizontal transmission must therefore be a key feature constraining the dis …

Site-specific selfish genes as tools for the control and genetic engineering of natural populations.
Burt A. Burt A. Proc Biol Sci. 2003 May 7;270(1518):921-8. doi: 10.1098/rspb.2002.2319. Proc Biol Sci. 2003. PMID: 12803906 Free PMC article.
Site-specific selfish genes exploit host functions to copy themselves into a defined target DNA sequence, and include homing endonuclease genes, group II introns and some LINE-like transposable elements. ...For example, a genetic load sufficient to eradicate a

Diversification in sexual and asexual organisms.
Barraclough TG, Birky CW Jr, Burt A. Barraclough TG, et al. Among authors: burt a. Evolution. 2003 Sep;57(9):2166-72. doi: 10.1111/j.0014-3820.2003.tb00394.x. Evolution. 2003. PMID: 14575336
Sexual reproduction has long been proposed as a major factor explaining the existence of species and species diversity. Yet, the importance of sex for diversification remains obscure because of a lack of critical theory, difficulties of applying universal concepts o …

Population genetics of the wild yeast Saccharomyces paradoxus.
Johnson LJ, Koufopanou V, Goddard MR, Hetherington R, Schäfer SM, Burt A. Johnson LJ, et al. Among authors: burt a. Genetics. 2004 Jan;166(1):43-52. doi: 10.1534/genetics.166.1.43. Genetics. 2004. PMID: 15020405 Free PMC article.
Here we characterize a set of 28 wild isolates from a 10-km(2) sampling area in southern England. All 28 isolates are homothallic (capable of mating-type switching) and wild type with respect to nutrient requirements. ...
