Flowering time divergence and genomic rearrangements in resynthesized Brassica polyploids (Brassicaceae) (2004, methodology): “Qualitative homoeologous gene expression was conducted by cDNA-SSCP analysis (Adams et al., 2003; Cronn & Adams, 2003).”
Widespread genome duplications throughout the history of flowering plants. (2006, methodology): “cDNA library construction, EST sequencing, and assembly were described previously (Albert et al. 2005).”
Evolutionary genetics of genome merger and doubling in plants. (2008, background): “One of the more spectacular recent revelations with respect to gene expression in polyploids is that homoeologous genes commonly make unequal contributions to the transcriptome, as shown most thoroughly to date in cotton and in wheat (2, 3, 11, 27, 40, 72).”
Gene duplication and evolutionary novelty in plants. (2009, background): “These findings are underscored by recent explorations of the transcriptomic response among synthetic allopolylpoids (Adams et al., 2003; J. Wang et al., 2006; Chaudhary et al., 2009; Ha et al., 2009), which suggest that dynamic expression changes may occur immediately upon allopolyploid formation.”
The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “New expression patterns of duplicated genes can also be a result of tissue specificity, also known as subfunctionalization, a process that has been suggested to operate over long evolutionary time frames (Adams et al., 2003).”
Hybridization, polyploidy and invasion: lessons from Spartina (Poaceae) (2009, background): “Gene silencing, unequal homeologous gene expression, and subfunctionalization, where a gene acquires different expression patterns, were demonstrated in both synthetic and natural allopolyploid cotton, which indicates that such immediate functional plasticity may operate over long periods of evoluti”

Spartina anglica C. E. Hubbard: a natural model system for analysing early evolutionary changes that affect allopolyploid genomes. (2004, background): “However, biased expression and epigenetically induced gene silencing have been recently demonstrated in both natural and synthetic allotetraploid Gossypium species (Adams et al., 2003; Adams & Wendel, 2004).”
Molecular mechanisms of polyploidy and hybrid vigor (2010, background): “Allelic expression variation varies from unequal expression of both alleles (biallelic) to expression of a single allele (monoallelic) in the hybrids, which is reminiscent of developmental reactivation of silenced rRNA genes in Brassica allotetraploids [77] and organ-specific reciprocal silencing in”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “The existence of multiple copies of one gene can lead to functional diversification, with one copy acquiring a new function (neofunctionalization) or a partitioning of expression patterns (subfunctionalization) that involves reciprocal (most likely epigenetic) silencing of each of the copies leading”
