Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, positive): “cause changes in the nucleus and in the overall cell architecture (Comai, 2005).”
Polyploidy and Crop Improvement (2006, background): “While it is not yet possible to predict the outcomes of these complex regulatory interactions for gene expression in polyploids, the process has been discussed and modeled in several important papers (Riddle and Birchler, 2003; Comai, 2005; Veitia, 2005).”
Plant speciation through chromosome instability and ploidy change: Cellular mechanisms, molecular factors and evolutionary relevance (2014, background): “More importantly, in most species apomixis has been found strongly correlated with genomic instability and polyploidy [25,125,126], suggesting that the process of apomeiosis not only confers asexual reproduction but also induces transgenerational ploidy increase, and hence drives evolutionary polypl”
The “Polyploid Hop”: Shifting Challenges and Opportunities Over the Evolutionary Lifespan of Genome Duplications (2018, background): “It was historically expected that an increase in gene number would result in a uniform increase in gene expression (Comai, 2005).”
Changing perspectives on regeneration ecology and genetic diversity in western quaking aspen: implications for silviculture (2012, neutral): “Triploids may be favored by natural selection in certain landscapes, either because of their vegetative vigor or because their triploid genome buffers them against the negative effects of mutation accumulation over time (see Comai 2005 and references therein).”
Plants with double genomes might have had a better chance to survive the Cretaceous–Tertiary extinction event (2009, background): “Although many changes associated with polyploidization are likely to be disadvantageous or deleterious (32, 33), the KT polyploids apparently did have a short-term evolutionary advantage, because many of them survived and outcompeted many, if not most, of their diploid progenitors (31).”
Geographical Parthenogenesis: Opportunities for Asexuality (2009, background): “Adams and Wendel 2005; Comai 2005; Chen 2007).”
Evolutionary genetics of genome merger and doubling in plants. (2008, background): “Much of this has been reviewed elsewhere (1, 4, 19, 20, 23, 53, 98, 115) but is reiterated here as a reminder of the myriad and diverse genomic responses to polyploidy.”
Homoeologs: What Are They and How Do We Infer Them? (2016, background): “Evolutionary biology Homoeologous: ‘duplicated genes or chromosomes that are derived from different parental species and are related by ancestry’ [98]”
Genetic, morphological, and chemical patterns of plant hybridization (2014, methodology): “Finally, allopolyploids usually show an increase of asexual reproduction that enable them to increase their population even in the absence of sexual mates (Comai 2005).”
