NEW TRAITS. "New and young polyploids typically display novel transcriptomic and/or proteomic phenomena, including biased gene expression with respect to homoeolog (duplicate gene copies resulting from polyploidy), expression level dominance with respect to the two different progenitor diploid genomes, and expression subfunctionalization (partitioning of aggregate ancestral expression among homoeologs) or neofunctionalization (novel expression domain or protein function)." http://www.amjbot.org/content/early/2015/10/09/ajb.1500320 View in LinkedIn

TIP OF THE ICEBERG. "The scale and scope of these phenomena vary among systems, genes, and genomic regions, and in most cases there is little understanding of phenotypic consequence or ecological or evolutionary significance." http://www.amjbot.org/content/early/2015/10/09/ajb.1500320 View in LinkedIn

DUPLICATION CONSEQUENCES. "Responses at the genomic (DNA) level include mutagenic gene silencing or deletional loss, intergenomic transfer of repetitive elements such as transposable elements, differential rates of accumulation of synonymous or nonsynonymous nucleotide substitutions, and various forms of homoeologous (duplicated copies generated by polyploidy) interaction or gene conversion that generate sequences chimeras or duplicated genes (shown as “recombination”)." http://www.amjbot.org/content/early/2015/10/09/ajb.1500320 View in LinkedIn

RANGE OF MULTIPLICATIONS. "Writ large, over the grand sweep of angiosperm history, we now understand that modern angiosperm genomes range in genomic complexity from those that have experienced few genomic multiplication events (e.g., Amborella, Allium, Olea, Theobroma) to others that reflect as many as 128 (Saccharum), 144 (Gossypium), and even 288 (Brassica) genomic multiples." http://www.amjbot.org/content/early/2015/10/09/ajb.1500320 View in LinkedIn

BREATHTAKING INSIGHTS. "Nowhere is the pace of progress more apparent than in plant evolutionary genomics, where the application of massively parallel sequencing approaches and advances in computational and bioinformatic capabilities have led to breathtaking insights about the structure, evolution, and function of plant genomes and their various genomic residents." https://lnkd.in/eiPytFX View in LinkedIn

ENRICHED HOUSEKEEPING GENES. "In general, single-copy genes are enriched for essential housekeeping functions and include genes targeted to the chloroplast and those involved in DNA repair and replication; they also are more highly and broadly expressed than are those retained in duplicate." http://www.amjbot.org/content/early/2015/10/09/ajb.1500320 View in LinkedIn
