The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae).
(2015-06)
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid ...
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 ...
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 ...
