Allopolyploidy has been a prominent mode of speciation and a recurrent process during
plant evolution and has contributed greatly to the large number of duplicated genes in plant …

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 …

Whole genome duplication (polyploidy) represents a primary mechanism of sympatric
speciation, especially in plants where it is particularly prevalent. In this chapter, we focus on …

The occurrence of polyploidy in land plant evolution has led to an acceleration of genome
modifications relative to other crown eukaryotes and is correlated with key innovations in …

Both ancient and recent polyploidy, together with post-polyploidization loss of many
duplicated gene copies, complicates angiosperm comparative genomics. To explore an …

Histone modifications regulate gene expression in eukaryotes, but their roles in gene
expression changes in interspecific hybrids or allotetraploids are poorly understood. Histone …

We developed a set of genetic markers specific to the A and D genome types of cotton using
representational difference analysis (RDA). These markers produce amplification products …

They have two copies of each gene, one from each parent. Comparative genomic studies,
however, suggest that we, along with yeast (Saccharomyces cerevisiae)(1), maize (2, 3) …

At least two whole-genome duplications (WGD) have profoundly influenced the evolution of
most, if not all, grass (Poaceae) genomes, with the most recent of these predating the …
