Striking Similarities in the Genomic Distribution of Tandemly Arrayed Genes in Arabidopsis and Rice (2006, methodology): “Blanc G, Wolfe KH (2004) Functional divergence of duplicated genes formed by polyploidy during Arabidopsis evolution.”
Polyploidy and Crop Improvement (2006, background): “In Arabidopsis, some classes of genes have been preferentially retained whereas other classes have been preferentially lost (Seoighe and Gehring, 2004; Blanc and Wolfe, 2004a; Blanc and Wolfe, 2004b; Chapman et al., 2006).”
The evolutionary significance of ancient genome duplications (2009, background): “Evidence from cytogenetic analyses, morphological studies of fossil and extant species and, more recently, whole-genome and EST analyses suggests that most (60–70%) flowering plants have a polyploid ancestr”
Genome‐size Variation in Switchgrass (Panicum virgatum): Flow Cytometry and Cytology Reveal Rampant Aneuploidy (2010, background): “However, in plants, polyploidy is present in nearly 80% of all living plants, and nearly 100% of all plant lineages have undergone a paleopolyploidy event in their history (Otto and Whitton, 2000; Blanc and Wolfe, 2004).”
Unraveling ancient hexaploidy through multiply-aligned angiosperm gene maps. (2008, background): “In our analysis, the inferred ancestral gene order was deduced by taking the consensus of the aligned gene orders among various chromosomes and scaffolds in the five species we investigated, similar to some previous approaches (Blanc et al. 2003).”
Opportunities and challenges Genome-wide analyses of alternative splicing in plants: (2008, positive): “Most plant genomes have undergone multiple genome duplication events during their evolutionary history (Paterson 2005), and some (e.g., soybean) have experienced very recent duplication events (Blanc and Wolfe 2004).”
Evolution of Gene Duplication in Plants1[OPEN] (2016, background): “…data led to the finding that plant genes involved in transcriptional regulation, signal transduction, and stress response tend to have paralogs (Blanc and Wolfe, 2004b; Maere et al., 2005; Shiu et al., 2005; Hanada et al., 2008) but those involved in essential functions, such as genome repair,…”
Plants with double genomes might have had a better chance to survive the Cretaceous–Tertiary extinction event (2009, background): “Our data suggest that the youngest WGD of Arabidopsis occurred 40 mya, which is more recent than the 65 or 72 mya previously proposed (17), but considerably older than the 25–30 mya proposed by Blanc and Wolfe (13), who also date the youngest WGDs in other plants such as Medicago, Gossypium, and Sol”
Widespread genome duplications throughout the history of flowering plants. (2006, background): “…clearly evident in the Ks distribution for hexaploid wheat because there has been little divergence among the parental or homeologous gene copies, and the range of divergence for allelic variants was not distinct from that of paralogs arising from recent gene duplications (Blanc and Wolfe 2004).”
The Genomes of Oryza sativa: A History of Duplications (2005, background): “In plants, the existence issue is not disputed, as polyploidy is common [48,49,50,51,52,53], but even with complete genome sequence, many details remain obscure.”
The advantages and disadvantages of being polyploid (2005, background): “The total number of chromosome sets is indicated by the prefix; for example, tri- (3), tetra- (4), penta- (5), hexa- (6) and octa- (8).”
