COLLATERAL EFFECTS. "From the scarce evidence available, we found that novel interactions are rare but that polyploidy can induce changes in pollinator, herbivore, and pathogen interactions." https://lnkd.in/bCmw3Fr View in LinkedIn

DIFFUSE EFFECT. "Although further tests are needed, it is likely that selection following whole-genome duplication is important in all types of species interaction and that there are circumstances in which polyploidy can enhance the evolvability of interactions with other species." https://lnkd.in/bCmw3Fr View in LinkedIn

POLYPLOIDY RULES. "We found that while certain rules may govern gene retention and loss, systems vary in the prevalence of gene silencing vs. homeolog loss, chromosomal change, the presence of a dominant genome (in allopolyploids), and the relative importance of hybridization vs. genome doubling per se." https://lnkd.in/bCmw3Fr View in LinkedIn

EXCEPTIONS EXIST. "In some lineages, aspects of polyploidization are repeated across multiple origins, but in other species multiple origins behave more stochastically in terms of genetic and phenotypic change." https://lnkd.in/bCmw3Fr View in LinkedIn

GENOTYPE-PHENOTYPE GAP. "Our investigation also reveals that the path to synthesis is hindered by numerous gaps in our knowledge of even the best-known systems. Particularly concerning is the absence of linkage between genotype and phenotype." https://lnkd.in/bCmw3Fr View in LinkedIn

GENOME DOWNSIZING. "Whole-genome duplications in plants are usually followed by rapid genome downsizing, or fractionation, which could reduce the correlation between genome size mean and ploidy level." https://lnkd.in/bCmw3Fr View in LinkedIn

GENOME SIZE AND PLOIDY. "The lack of correlation could be due to the accumulation of transposable elements or the removal of large blocks of DNA via intra-strand homologous recombination and illegitimate recombination events." https://lnkd.in/bCmw3Fr View in LinkedIn

TRANSPOSABLE ELEMENTS. "Genome size changes also have been associated with recombination rates. Genome size encompasses the net difference between increases and decreases of functional and non-functional DNA." https://lnkd.in/bCmw3Fr View in LinkedIn

WHOLE GENOME DUPLICATION (WGD) may be difficult or impossible in species with large genomes if large genome sizes increase nutrient demands or if large genomes are associated with cellular traits that cannot scale with the duplication." https://lnkd.in/bCmw3Fr View in LinkedIn
