Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

McGrath et al., 2014; Scienski et al., 2015) revealed that many eukaryotes do indeed have a
polyploid ancestry. Although there have been recent debates on the average fate of …

Polyploidy is a dominant feature of extant plant diversity. However, major research
questions, including whether polyploidy is important to long‐term evolution or is just …

Autopolyploidy is more common in plants than traditionally assumed, but has received little
attention compared with allopolyploidy. Hence, the advantages and disadvantages of …

Whole genome duplication (WGD), which gives rise to polyploids, is a unique type of
mutation that duplicates all the genetic material in a genome. WGD provides an evolutionary …

During the past decade, molecular techniques have provided a wealth of data that have
facilitated the resolution of several controversial questions in polyploid evolution. Herein we …

Polyploidy, or the presence of two or more diploid parental genome sets within an organism,
is found to an amazing degree in higher plants. In addition, many plant species traditionally …

Polyploidy is important in the evolutionary history of plants, and it has played a crucial role in
shaping the genome structures of all eukaryotes. New and rapidly improving techniques in …

Background Throughout the past century, hybridization and polyploidization have variously
been viewed as drivers of biodiversity (eg Arnold, 1997) or evolutionary noise, unimportant …
