PLANT GENETIC HISTORIES. "Although polyploidy may have experienced a nadir of interest during the latter half of the 20th century, the sequencing and analyses of plant genomes have revealed numerous cycles of polyploidy in the history of nearly all land plants." https://lnkd.in/bCmw3Fr View in LinkedIn

NUMEROUS STARTS. "A unique aspect of polyploidy is that many polyploid species may trace their ancestry to numerous, independent origins." https://lnkd.in/bCmw3Fr View in LinkedIn

SPECIATION. "Polyploidy has long been proposed as a mechanism of “instant speciation”, but empirical analyses of this contention are relatively rare." https://lnkd.in/e5Q_ate View in LinkedIn

TRANSITION STATE. "Polyploidy has long been hypothesized to be associated with transitions in sexual systems in flowering plants, and alternatively hypothesized to be associated with both monoecy and dioecy." https://lnkd.in/e5Q_ate View in LinkedIn

EXAPTATION. "Recent analyses have demonstrated that neofunctionalization of paralogs from ancient polyploidy have driven a chemical arms race between plants of the Brassicales and their pierid butterfly herbivores." https://lnkd.in/e5Q_ate View in LinkedIn

GENE DUPLICATION. "He proposed the now familiar concept that these polyploid plants were fertile because genome doubling restored chromosome pairing in otherwise sterile hybrids. The restoration of fertility to sterile hybrids by doubling their genomes was a potent and elegant demonstration of how postzygotic reproductive isolation could be solved." https://lnkd.in/e5Q_ate View in LinkedIn

PLANT POLYPLOIDY. "There is consensus that polyploidy has contributed to the evolution of nearly all lineages of vascular plants." https://lnkd.in/e5Q_ate View in LinkedIn

TRIUMPH OF DUPLICATION. "Speciation by genome duplication was recognized early in the study of evolutionary genetics and “represented the first major triumph in the genetics of speciation”. http://scholar.google.com/ View in LinkedIn

PARSING OLD GENES. "One of the primary goals of our work on gene duplication is to explain the shortcomings of the classical model, which postulates that the usual fate of a duplicated gene is either conversion to a nonfunctional pseudogene or acquisition of a new function. We believe that duplicate genes are frequently preserved through a partitioning of functions of ancestral genes (subfunctionalization), rather than by the evolution of new functions." https://lnkd.in/e8G48jD View in LinkedIn
