The BOY NAMED SUE Quantitative Trait Locus Confers Increased Meiotic Stability to an Adapted Natural Allopolyploid of Arabidopsis
Whole-genome duplication resulting from polyploidy is ubiquitous in the evolutionary history
of plant species. Yet, polyploids must overcome the meiotic challenge of pairing …

Approximately 90% of Arabidopsis' unique gene content is found in syntenic blocks that
were formed during the most recent whole-genome duplication. Within these blocks, 28.6 …

Genomic changes in synthetic Arabidopsis polyploids
Polyploids are common and arise frequently by genome duplication (autopolyploids) or
interspecific hybridization (allopolyploids). Neoallopolyploids display sterility, lethality …

[HTML][HTML] Modes of gene duplication contribute differently to genetic novelty and redundancy, but show parallels across divergent angiosperms
Background Both single gene and whole genome duplications (WGD) have recurred in
angiosperm evolution. However, the evolutionary effects of different modes of gene …

[HTML][HTML] Preferential retention of genes from one parental genome after polyploidy illustrates the nature and scope of the genomic conflicts induced by hybridization
Polyploidy is increasingly seen as a driver of both evolutionary innovation and ecological
success. One source of polyploid organisms' successes may be their origins in the merging …
