Haibao Tang
Plant Genome Mapping Laboratory, University of Georgia, Athens, Georgia 30602, USA
Genome Res 18:1944-54. 2008
..Comparative analysis of inferred homologous genes derived from this model shows patterns of preferential gene retention or loss after polyploidy and reveals large variability of nucleotide substitution rates among plant nuclear genomes...
- Angiosperm genome comparisons reveal early polyploidy in the monocot lineage
Haibao Tang
Plant Genome Mapping Laboratory, University of Georgia, Athens, GA 30602, USA
Proc Natl Acad Sci U S A 107:472-7. 2010
..Although the exact timing of the sigma-duplication(s) is unclear because of uncertainties of the molecular clock assumption, our data suggest that it occurred early in the monocot lineage after its divergence from the eudicot clade...
- The Sorghum bicolor genome and the diversification of grasses
Andrew H Paterson
Plant Genome Mapping Laboratory, University of Georgia, Athens, Georgia 30602, USA
Nature 457:551-6. 2009
..About 24% of genes are grass-specific and 7% are sorghum-specific. Recent gene and microRNA duplications may contribute to sorghum's drought tolerance...

Xiyin Wang
Plant Genome Mapping Laboratory, University of Georgia, Athens, Georgia 30602, USA
Genome Res 19:1026-32. 2009

- Synteny and collinearity in plant genomes
Haibao Tang
Plant Genome Mapping Laboratory, University of Georgia, Athens, GA 30602, USA
Science 320:486-8. 2008

Xiyin Wang
Plant Genome Mapping Laboratory, University of Georgia, Athens, 30602, USA
BMC Genomics 12:470. 2011
..Evolution of the Brassica species has been recursively affected by polyploidy events, and comparison to their relative, Arabidopsis thaliana, provides means to explore their genomic complexity...
- Modes of gene duplication contribute differently to genetic novelty and redundancy, but show parallels across divergent angiosperms
Yupeng Wang
Plant Genome Mapping Laboratory, University of Georgia, Athens, Georgia, United States of America
PLoS ONE 6:e28150. 2011
