Polyploidy (whole-genome duplication) has played a perva sive role in the evolution of fungi
and animals, and is partic ularly prominent in plants (Wendel & Doyle, 2005; Cui et al, 2006; …

Highlights•Dosage balance is fluid and will change over time.•Duplicate genes are
preserved by interplay of multiple overlapping mechanisms.•Distinguishing duplicate gene …

During the past decade there has been a tremendous resurgence of interest in polyploidy
that has in large part been stimulated by the development of increasingly powerful genetic …

Polyploidy (whole-genome duplication; WGD) is common in plants and has long been
considered as both an important speciation mechanism and a crucial component of plant …

Allopolyploidy is a prevalent process in plants, having important physiological, ecological
and evolutionary consequences. Transcriptomic responses to genomic merger and doubling …

Gene duplication, arising from region-specific duplication or genome-wide polyploidization,
is a prominent feature in plant genome evolution. Understanding the mechanisms …

Polyploidization, a widespread phenomenon among plants, is considered a major
speciation mechanism. Polyploid plants have a high degree of immediate post-zygotic …

In this chapter some of the salient features of polyploidy in plants, including a brief
description of its prevalence and modes of formation are discussed. Several model systems …

• Premise of the study: Hybridization and polyploidization (allopolyploidy) are ubiquitous in
the evolution of plants, but tracing the origins and subsequent evolution of the constituent …

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 …
