QUESTION 3. "Does polyploidy lead to greater evolvability in species interactions?" https://lnkd.in/bCmw3Fr View in LinkedIn

LIMITING TRANSPOSABLE ELEMENTS. "They concluded that some lineages might be more successful than others at reducing or preventing proliferation of transposable elements that ultimately contribute to genome size determination in cotton." https://lnkd.in/bCmw3Fr View in LinkedIn

OVERLOOKED. "While the role of genome downsizing following WGD is widely acknowledged, the role of genomic constraints on WGDs has received relatively little attention." (WGD = whole genome duplication). https://lnkd.in/bCmw3Fr View in LinkedIn

"GENOME DOWNSIZING appears to affect the average genome sizes, especially at tetraploid level, but our results emphasize the importance of constraints on genome size or monoploid number." https://lnkd.in/bCmw3Fr View in LinkedIn

CONSTRAINT. "For taxa with many chromosomes, WGDs could also be detrimental if the total number of chromosomes impedes homologous chromosome recognition during meiosis following a WGD." (WGD = whole genome duplication). 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

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

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

REPRODUCTIVE GENES. Angiosperm "genes specifically expressed in reproductive organs (i.e., stamen) evolve more quickly than those specifically expressed in vegetative organs (e.g., root). The different rates in organ evolution may be due to different degrees of functional constraint associated with the different physiological functions of plant organs." https://lnkd.in/e7nzq_s View in LinkedIn

PROMISCUOUS INCORPORATION. "Angiosperm mtDNAs incorporate foreign sequences remarkably often, from chloroplast and nuclear genomes of the same plant via intracellular gene transfer, and from other plants via horizontal gene transfer." http://onlinelibrary.wiley.com/doi/10.1111/nph.13188/full View in LinkedIn
