这篇综述系统探讨了马铃薯（Solanum section Petota）多倍体化（polyploidy）在气候适应性中的关键作用，揭示了多倍体（如四倍体2n=4x=48）通过基因组加倍（whole-genome duplication）、杂交（hybridization）和双还原（double reduction）等机制增强抗逆性的潜力。文章强调野生马铃薯资源（CWRs）的遗传多样性对培育 ...

Polyploidy is intimately associated with sex because asexual plants and animals are often of higher ploidy level than closely related sexual taxa (Bierzychudek, 1985; Suomalainen et al., 1987 ...

A new study, led by experts at the University of Nottingham, has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into ...

Polyploidy often occurs in human diseases and cancers, and its effect on cell fate was unclear. Now, however, researchers from Japan have shown that polyploidy can be a double-edged sword when it ...

In plants, polyploidy can cause reproductive isolation and the consequent onset of new species. Researchers now set out to estimate to what extent polyploidy is involved in the onset of the ...

The role of polyploidy per se in the development of evolutionary novelty remains one of the outstanding questions in flowering plant evolution. Since chromosome doubling usually is associated with ...

Polyploidy and long-distance dispersal jointly shape global species diversification in yellowcress, finds study Long-distance dispersal (LDD) is one of the most important biogeographical processes.

Highlighting polyploidy's potential to enhance crop yields and qualities, the review advocates for its application in vegetable breeding for economic and dietary benefits.

Leading expert on plant evolution and speciation and professor of Iowa State University, Jonathan Wendel, presented his research Thursday on cotton genomes and polyploidy in his presentation “Genes, ...
