Genetic and epigenetic mechanisms for gene expression and phenotypic variation in plant polyploids
ZJ Chen - Annu. Rev. Plant Biol., 2007 - annualreviews.org
Polyploidy, or whole-genome duplication (WGD), is an important genomic feature for all
eukaryotes, especially many plants and some animals. The common occurrence of …

Temporal transcriptome profiling reveals expression partitioning of homeologous genes contributing to heat and drought acclimation in wheat (Triticum aestivum L.)
Z Liu, M Xin, J Qin, H Peng, Z Ni, Y Yao, Q Sun - BMC plant biology, 2015 - Springer
Abstract Background Hexaploid wheat (Triticum aestivum) is a globally important crop. Heat,
drought and their combination dramatically reduce wheat yield and quality, but the …

Gossypium barbadense genome sequence provides insight into the evolution of extra-long staple fiber and specialized metabolites
Of the two cultivated species of allopolyploid cotton, Gossypium barbadense produces extra-
long fibers for the production of superior textiles. We sequenced its genome (AD) 2 and …

Functional divergence of duplicated genes formed by polyploidy during Arabidopsis evolution
To study the evolutionary effects of polyploidy on plant gene functions, we analyzed
functional genomics data for a large number of duplicated gene pairs formed by ancient …

Genome downsizing in polyploid plants
IJ Leitch, MD Bennett - Biological journal of the Linnean Society, 2004 - academic.oup.com
All else being equal, polyploids are expected to have larger C-values (amount of DNA in the
unreplicated gametic nucleus) than their diploid progenitors, increasing in direct proportion …

Genes duplicated by polyploidy show unequal contributions to the transcriptome and organ-specific reciprocal silencing
Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which
seems to have arisen from one or more cycles of genome doubling. Polyploidy has been …
