Diploidization and genome size change in allopolyploids is associated with differential dynamics of low- and high-copy sequences
(2013-06-01)
Summary Recent advances have highlighted the ubiquity of whole-genome duplication (polyploidy) in angiosperms, although subsequent genome size change and diploidization (returning to a diploid-like condition) are poorly ...
Analysis of the giant genomes of Fritillaria (Liliaceae) indicates that a lack of DNA removal characterizes extreme expansions in genome size.
(Wiley Online, 2015-06-08)
Plants exhibit an extraordinary range of genome sizes, varying by > 2000-fold between the smallest and largest recorded values. In the absence of polyploidy, changes in the amount of repetitive DNA (transposable elements ...
Molecular footprints of the Holocene retreat of dwarf birch in Britain
(2014-01-01)
Past reproductive interactions among incompletely isolated species may leave behind a trail of introgressed alleles, shedding light on historical range movements. Betula pubescens is a widespread native tetraploid tree ...
Genome-wide haplotype analysis improves trait predictions in Brassica napus hybrids
(Elsevier, 2019-06-01)
Combining ability is crucial for parent selection in crop hybrid breeding. Many studies have attempted to provide reliable and quick methods to identify genome regions in parental lines correlating with improved hybrid ...
