As a major driving force of evolution, polyploidy (genome duplication) is ubiquitous across different evolutionary stages of the flowering plant tree of life. However, the interactions between the ...

WEST LAFAYETTE, Ind. - A study out of Harvard and Purdue universities is starting to unravel the genetic mechanisms that allow some plants to duplicate their entire genomes and continue to reproduce.

Polyploidy, or whole-genome duplication (WGD), is a major mechanism of genome evolution across the tree of life and is particularly prevalent in plants, where it facilitates the evolution of new ...

In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and one on distribution and ...

Polyploid genomes, formed through repeated whole-genome duplication and hybridization, underpin the evolution of many important crops, yet their internal structure often remains unresolved when ...

A research team has elucidated the role of polyploidy in the evolution and breeding of vegetable crops, leveraging advanced sequencing technologies to dissect the genetic and epigenetic nuances of ...

Ferns, defined by large genomes, high chromosome counts, and pervasive aneuploidy as well as intraspecific polyploid complexity, diverge significantly from the classical genetic theories and ...
